perf symbols: Fix a mmap and munmap mismatched bug (2013-10-14 12:21:23 -0300)
----------------------------------------------------------------
perf/core improvements and fixes
. kcore annotation improvements, including build-id cache support,
multi map 'call' instruction navigation fixes, kcore address
validation, objdump workarounds. From Adrian Hunter.
. 'trace' beautifiers for lots of syscall arguments.
. More compact 'trace' output by suppressing zeroed args.
. Show thread COMM by default in 'trace'.
. Show path associated with fd in live sessions, using a 'vfs_getname'
'perf probe' created dynamic tracepoint or by looking at /proc/pid/fd.

. Fix comm resolution in 'trace' when reading events from file, from David Ahern.
. Improved messages when doing profiling in all or a subset of CPUs
using a workload as the session delimitator, as in:
'perf stat --cpu 0,2 sleep 10s'
. Add units to nanosec-based counters in 'perf stat', from David Ahern.
. Assorted build fixes for from David Ahern and Jiri Olsa.
. 'perf lock' fixes and cleanups, from Davidlohr Bueso.
. Memory leak fixes in 'perf test', from Felipe Pena.
. Build system super speedups, from Ingo Molnar.
. Fix mmap_read event overflow, from Jiri Olsa.
. Code cleanups from Jiri Olsa.
. Allow specifying B/K/M/G unit to the --mmap-pages arguments, from Jiri Olsa.
. Separate the GTK support in a separate libperf-gtk.so DSO, that is
only loaded when --gtk is specified, from Namhyung Kim.
. Fixes for some memory leaks, from Namhyumg Kim.
. Fix srcline sort key behavior, from Namhyung Kim.
. Fix failing assertions in numa bench, from Petr Holasek.
. perf bash completion fixes and improvements from Ramkumar Ramachandra.
. Improve error messages in 'trace', providing hints about system configuration
steps needed for using it, from Ramkumar Ramachandra.

From: Ingo Molnar <[email protected]>
In case the user specifies MAKEFLAGS as an environment variable,
or uses 'make -jN' explicitly, the options can conflict and result in:
BUILD: Doing 'make -j8' parallel build
make[1]: warning: -jN forced in submake: disabling jobserver mode.
GEN common-cmds.h
make[1]: *** write jobserver: Bad file descriptor. Stop.
Make sure we invoke the main makefile in a pristine state.
Users who want to do something non-standard can use the:
make -f Makefile.perf
method to invoke the makefile.

1.8.1.4
From: Adrian Hunter <[email protected]>
kcore can be used to view the running kernel object code. However,
kcore changes as modules are loaded and unloaded, and when the kernel
decides to modify its own code. Consequently it is useful to create a
copy of kcore at a particular time. Unlike vmlinux, kcore is not unique
for a given build-id. And in addition, the kallsyms and modules files
are also needed. The tool therefore creates a directory:
~/.debug/[kernel.kcore]/<build-id>/<YYYYmmddHHMMSShh>
which contains: kcore, kallsyms and modules.
Note that the copied kcore contains only code sections. See the
kcore_copy() function for how that is determined.
The tool will not make additional copies of kcore if there is already
one with the same modules at the same addresses.
Currently, perf tools will not look for kcore in the cache. That is
addressed in another patch.

+ *
+ * This function copies kallsyms, modules and kcore files from one directory to
+ * another. kallsyms and modules are copied entirely. Only code segments are
+ * copied from kcore. It is assumed that two segments suffice: one for the
+ * kernel proper and one for all the modules. The code segments are determined
+ * from kallsyms and modules files. The kernel map starts at _stext or the
+ * lowest function symbol, and ends at _etext or the highest function symbol.
+ * The module map starts at the lowest module address and ends at the highest
+ * module symbol. Start addresses are rounded down to the nearest page. End
+ * addresses are rounded up to the nearest page. An extra page is added to the
+ * highest kernel symbol and highest module symbol to, hopefully, encompass that
+ * symbol too. Because it contains only code sections, the resulting kcore is
+ * unusual. One significant peculiarity is that the mapping (start -> pgoff)
+ * is not the same for the kernel map and the modules map. That happens because
+ * the data is copied adjacently whereas the original kcore has gaps. Finally,
+ * kallsyms and modules files are compared with their copies to check that
+ * modules have not been loaded or unloaded while the copies were taking place.
+ *
+ * Return: %0 on success, %-1 on failure.

1.8.1.4
From: Ingo Molnar <[email protected]>
If someone specifies a single target, mixed with O=, the following way:
hubble:~/tip/tools/perf> make O=/tmp/perf util/stat.o
BUILD: Doing 'make -j8' parallel build
gcc -Wbad-function-cast -Wdeclaration-after-statement -Wformat-security -Wformat-y2k [...]
The build might even fail, if a target depends on other targets:
hubble:~/tip/tools/perf> make O=/tmp/perf perf.o
...
perf.c: In function ‘handle_options’:
perf.c:155:21: error: ‘PERF_HTML_PATH’ undeclared (first use in this function)
The correct way to invoke such targets is:
hubble:~/tip/tools/perf> make O=/tmp/perf /tmp/perf/perf.o
BUILD: Doing 'make -j8' parallel build
GEN /tmp/perf/common-cmds.h
CC /tmp/perf/perf.o
But that's unnecessary typing and it's also easy to mistakenly build into the
source directory.
To fix this remove the generic suffix rules and add redirection to $(OUTPUT)
for the most popular .o targets.

1.8.1.4
From: Ingo Molnar <[email protected]>
libtraceevent.a and liblk.a rules have always-missed dependencies,
which causes python.so to be relinked at every build attempt - even
if none of the affected code changes.
This slows down re-builds unnecessarily, by adding more than a second
to the build time:
comet:~/tip/tools/perf> time make
...
SUBDIR /fast/mingo/tip/tools/lib/lk/
make[1]: `liblk.a' is up to date.
SUBDIR /fast/mingo/tip/tools/lib/traceevent/
LINK perf
GEN python/perf.so
real 0m1.701s
user 0m1.338s
sys 0m0.301s
Add the (trivial) dependencies to not force a re-link.
This speeds up an empty re-build enormously:
comet:~/tip/tools/perf> time make
...
real 0m0.207s
user 0m0.134s
sys 0m0.028s
[ This adds some coupling between the build dependencies of
libtraceevent and liblk - but until those stay relatively
simple this should not be an issue. ]

When following a call, annotate_browser__callq() uses the current
symbol's map to look up the target ip. That will not work if the target
ip is on a map with a different mapping (i.e. start - pgoff is
different).

Implement automatic parallel builds when building in tools/perf:
$ time make
# [ perf build: Doing 'make -j12' parallel build. ]
Auto-detecting system features:
...
real 0m9.265s
user 0m59.888s
sys 0m6.082s
On GNU make achieving this is not particularly easy, it requires a separate
makefile, which then invokes the main Makefile.
( Note: this patch adds Makefile.parallel to show the concept - the two
makefiles will be flipped in the next patch to avoid having to specify -f
to get parallelism in the default build. )

The objdump tool fails to annotate module symbols when looking at kcore.
Workaround this by extracting object code from kcore and putting it in a
temporary file for objdump to use instead.
The temporary file is created to look like kcore but contains only the
function being disassembled.

1.8.1.4
From: Ingo Molnar <[email protected]>
Linus reported the following perf build system bug:
'Another annoyance during that make was that "make install" seems to
want to re-make the thing I just built. That's absolutely horrible, [...]'
The thing that got re-built were 'only' the (numerous) feature checks,
not the whole project - but still it was mighty annoying as the feature
checks took 9+ seconds even on reasonably fast boxes.
Even with the autodep patches where feature detection is much faster
it wastes resources, wastes screen real estate and confuses users if
we execute feature detection twice.
There were two sources for these unnecessary re-builds of the feature
checks:
- Unnecessary nested invocations of $(MAKE), apparently to be able
to do conditional compilation dependent on documentation tools
presence. Use straight dependencies instead, with no nesting.
- A direct invocation of $(MAKE) to rebuild the PERF-VERSION-FILE.
This is apparently done to be able to include it into the
Makefile:
-include $(OUTPUT)PERF-VERSION-FILE
but that's entirely pointless for two reasons: 1) the version file
gets regenerated by the initial build pass anyway, 2) including it
is futile, given its contents:
#define PERF_VERSION "3.12.rc3.g8510c7"
'make' will interpret that as a comment line...
So just remove this part of the doc-generation logic.
With these things fixed a 'make install' now rebuilds only what is needed.
A repeated 'make install' on an already built tree is super fast now,
it finishes in under 0.3 seconds:
#
# After the patch:
#
$ time make install
...
real 0m0.280s
user 0m0.162s
sys 0m0.054s
Prior all the autodep changes and prior this fix, a repeat 'make install'
took 24.1 seconds (!) on the same system:
#
# Before the patches:
#
$ time make install
...
real 0m24.109s
user 0m21.171s
sys 0m2.449s
Which almost entirely was caused by fixable build system fat.
We are now literally ~86 times faster.
A fresh rebuild and install now takes just 11.4 seconds:
#
# After the patch:
#
$ make clean
$ time make -j16 install
...
real 0m11.457s
user 1m43.411s
sys 0m7.610s
Without the patches it took 27.8 seconds:
#
# Before the patches:
#
$ make clean
$ time make -j16 install
...
real 0m27.801s
user 1m59.242s
sys 0m9.749s
So even in the complete rebuild case we are now ~2.5 times faster.

Namhyung Kim noticed that the stackprotector testcase was incomplete:

Add -Wstack-protector.

'make clean' used to show all the rm lines, which isn't really
informative in any way and spams the console.
Implement summary output:

CLEAN libtraceevent
CLEAN liblk
CLEAN config
CLEAN core-objs
CLEAN core-progs
CLEAN core-gen
CLEAN Documentation
CLEAN python
'make clean V=1' will still show the old, detailed output.

1.8.1.4
From: Chenggang Qin <[email protected]>
In function filename__read_debuglink(), while the ELF file is opend and
mmapped in elf_begin(), but if this file is considered to not be usable
during the following code, we will goto the close(fd) directly. The
elf_end() is skipped. So, the mmaped ELF file cannot be munmapped. The
mmapped areas exist during the life of perf.
This is a memory leak. This patch fixed this bug.

From: Jiri Olsa <[email protected]>
Moving start conditions to start of the flex file so it's clear what the
INITIAL condition rules are.
Plus adding default rule for INITIAL condition. This prevents default
space to be printed for events like:
$ ./perf stat -e "cycles " kill 2>/dev/null
$

1.8.1.4
From: Ingo Molnar <[email protected]>
Arnaldo reported that 'make DEBUG=1' does not work anymore.
The reason is that 'Makefile' only passes it through to
'Makefile.perf' via the environment, but 'Makefile.perf'
checks that it's a command line option:
ifeq ("$(origin DEBUG)", "command line")
PERF_DEBUG = $(DEBUG)
endif
So pass it through properly, and also clean up DEBUG parameter
handling while at it and fix a couple of annoyances:
- DEBUG=0 used to be interpreted as 'debugging on'. Turn it
into 'debugging off' instead.
- Same was the case for 'DEBUG=' - turn that into debug-off
as well.
- Pass in just a clean, sanitized 'DEBUG' value and get rid of
the intermediate, unnecessary PERF_DEBUG variable.

1.8.1.4
From: Ingo Molnar <[email protected]>
util/PERF-VERSION-GEN is currently executed on every build attempt,
and this script can take a lot of time on trees that are at a
significant git-distance from Linus's tree:
$ time util/PERF-VERSION-GEN
real 0m4.343s
user 0m4.176s
sys 0m0.140s
It also takes a lot of time if the Git repository is network attached, etc.,
because the commands it uses:
TAG=$(git describe --abbrev=0 --match "v[0-9].[0-9]*" 2>/dev/null )
has to count commits from the nearest tag and thus has to access (and
decompress) every git commit blob on the relevant version path.
Even on Linus's tree it takes 0.28 seconds on a fast box to count all the
commits and get the git version string:
$ time util/PERF-VERSION-GEN
real 0m0.279s
user 0m0.247s
sys 0m0.025s
But the version string only has to be regenerated if the git repository's
head commit changes. So add a dependency of ../../.git/HEAD and touch
the file every time it's regenerated, so that Make's build rules can
pick it up and cache the result:
make: `PERF-VERSION-FILE' is up to date.

syscalls, but other system events like pagefaults, task lifetime events,
scheduling events, etc.
-Initially this is a live mode only tool, but eventually will work with
-perf.data files like the other tools, allowing a detached 'record' from
-analysis phases.
+This is a live mode tool in addition to working with perf.data files like
+the other perf tools. Files can be generated using the 'perf record' command
+but the session needs to include the raw_syscalls events (-e 'raw_syscalls:*').
+Alernatively, the 'perf trace record' can be used as a shortcut to
+automatically include the raw_syscalls events when writing events to a file.

+The following options apply to perf trace; options to perf trace record are

From: Jiri Olsa <[email protected]>
We fail build with NO_DEMANGLE with missing -lbfd externals error.
The reason is that we now use bfd code in srcline object:
perf tools: Implement addr2line directly using libbfd
So we need to check/add -lbfd always now.

1.8.1.4
From: Adrian Hunter <[email protected]>
Before using kcore we need to check that modules are in memory at the
same addresses that they were when data was recorded.
This is done because, while we could remap symbols to different
addresses, the object code linkages would still be different which would
provide an erroneous view of the object code.

1.8.1.4
From: Arnaldo Carvalho de Melo <[email protected]>
For live sessions we can just access /proc to map an fd to its path, on
a best effort way, i.e. sometimes the fd will have gone away when we try
to do the mapping, as it is done in a lazy way, only when a reference to
such fd is made then the path will be looked up in /proc.
This is disabled when processing perf.data files, where we will have to
have a way to get getname events, be it via an on-the-fly 'perf probe'
event or after a vfs_getname tracepoint is added to the kernel.
A first step will be to synthesize such event for the use cases where
the threads in the monitored workload exist already.

Right now when an index passed to that method has no string associated
it'll print the index as a decimal number, prepare it so that we can use
it to print it in hex as well, for ioctls, for instance.

So that the index passed doesn't have to start at zero, being
decremented from an offset specified when declaring the strarray before
being used as the real array index.

If we build perf with NO_LIBPYTHON=1 NO_LIBPERL=1 the '-ldl' is not
added to libs build fails if we have gtk2 code in, because it depends on
it.

1.8.1.4
From: Jiri Olsa <[email protected]>
The perf_evlist__mmap_read used 'union perf_event' as a placeholder for
event crossing the mmap boundary.
This is ok for sample shorter than ~PATH_MAX. However we could grow up
to the maximum sample size which is 16 bits max.
I hit this overflow issue when using 'perf top -G dwarf' which produces
sample with the size around 8192 bytes. We could configure any valid
sample size here using: '-G dwarf,size'.
Using array with sample max size instead for the event placeholder. Also
adding another safe check for the dynamic size of the user stack.
TODO: The 'struct perf_mmap' is quite big now, maybe we could use some
lazy allocation for event_copy size.

'make install' used to show all the install lines, which is way too
verbose to be really informative to the user.
Implement summary output instead:
comet:~/tip/tools/perf> make install
BUILD: Doing 'make -j12' parallel build
SUBDIR Documentation
INSTALL Documentation-man
INSTALL binaries
INSTALL libexec
INSTALL perf-archive
INSTALL perl-scripts
INSTALL python-scripts
INSTALL bash_completion-script
INSTALL tests
'make install V=1' will still show the old, detailed output.

I.e. looking for futex calls that take at least 15ms, system wide, during a one
second window. Now to get callchains into 'trace' to figure out what are those
locks :-)

Arnaldo reported that non-existent build directories were not
recognized properly. The reason is readlink failure causing 'O'
to become empty.
Solve it by passing through the 'O' variable unmodified if
readlink fails.

From: Ingo Molnar <[email protected]>
Namhyung Kim noticed that the volatile-register-var feature check
is superfluous:
> The gcc manpage says this warning is enabled by -Wall, and we add -Wall
> to CFLAGS before doing feature checks. So all gcc versions that support
> -Wvolatile-register-var enables it by default without this check and

Remove it - this will further speed up feature checks.

Namhyung Kim reported these duplicate DPACKAGE definitions:
test-libbfd:
$(BUILD) -DPACKAGE='perf' -DPACKAGE=perf -lbfd -ldl
Fix all affected places and use Namhyung's suggestion that the
definition should look like a normal C string: -DPACKAGE='"perf"'.

1.8.1.4
From: Jiri Olsa <[email protected]>
Adding possibility to specify mmap size via -m/--mmap-pages
by appending unit size character (B/K/M/G) to the
number, like:
$ perf record -m 8K ls
$ perf record -m 2M ls
The size is rounded up appropriately to follow perf
mmap restrictions.
If no unit is specified the number provides pages as
of now, like:
$ perf record -m 8 ls

Loop over all threads within a machine - including threads moved to the
dead threads list -- and invoked a function.
This allows commands to run some specific function on each thread (eg.,
dump statistics) yet hides how the threads are maintained within the
machine.

1.8.1.4
From: David Ahern <[email protected]>
Task comm's are getting lost when processing events from a file. The
problem is that the trace struct used by the live processing has its
host machine and the perf-session used for file based processing has its
host machine. Fix by having both references point to the same machine.

The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:
CC builtin-buildid-list.o
CC builtin-buildid-cache.o
CC builtin-list.o
CC FPIC trace-seq.o
CC builtin-record.o
CC FPIC parse-filter.o
CC builtin-report.o
CC builtin-stat.o
CC FPIC parse-utils.o
CC FPIC kbuffer-parse.o
CC builtin-timechart.o
CC builtin-top.o
CC builtin-script.o
BUILD STATIC LIB libtraceevent.a
CC builtin-probe.o
CC builtin-kmem.o
CC builtin-lock.o
To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.
After the patch the output looks pretty tidy, even if output lines get
mixed up:
CC builtin-annotate.o
FLAGS: * new build flags or cross compiler
CC builtin-bench.o
AR liblk.a
CC bench/sched-messaging.o

1.8.1.4
From: David Ahern <[email protected]>
Ingo pointed out that the task-clock counter should have the units
explicitly stated since it is not a counter.
Before:
perf stat -a -- sleep 1
Performance counter stats for 'sleep 1':
16186.874834 task-clock # 16.154 CPUs utilized
...
After:
perf stat -a -- sleep 1
Performance counter stats for 'system wide':
16146.402138 task-clock (msec) # 16.125 CPUs utilized
...

From: Jiri Olsa <[email protected]>
Move the check of the mmap_pages value to the options parsing time, so
we could rely on this value on other parts of code.
Related changes come in the next patches.
Also changes perf_evlist::mmap_len to proper size_t type.

1.8.1.4
From: Ramkumar Ramachandra <[email protected]>
Currently, execution of 'perf trace' reports the following cryptic
message to the user:
$ perf trace
Couldn't read the raw_syscalls tracepoints information!
Typically this happens because the user does not have permissions to
read the debugfs filesystem. Also handle the case when the kernel was
not compiled with debugfs support or when it isn't mounted.
Now, the tool prints detailed error messages:
$ perf trace
Error: Unable to find debugfs
Hint: Was your kernel was compiled with debugfs support?
Hint: Is the debugfs filesystem mounted?
Hint: Try 'sudo mount -t debugfs nodev /sys/kernel/debug'
$ perf trace
Error: No permissions to read /sys/kernel/debug//tracing/events/raw_syscalls
Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug/'

From: Roberto Vitillo <[email protected]>
When the srcline sort key is used , the external addr2line utility needs
to be run for each hist entry to get the srcline info. This can consume
quite a time if one has a huge perf.data file.
So rather than executing the external utility, implement it internally
and just call it. We can do it since we've linked with libbfd already.

Moving 'struct throttle_event' out of python code and making it global

There's no usage of throttling events in any perf commands so far
(besides python support), but we'll need this event data backup for
upcoming test.

Separate out GTK codes to a shared object called libperf-gtk.so. This
time only GTK codes are built with -fPIC and libperf remains as is. Now
run GTK hist and annotation browser using libdl.

1.8.1.4
From: Davidlohr Bueso <[email protected]>
This function should be straightforward, and we can remove some trivial
logic by moving the functionality of read_events() into __cmd_report() -
thus allowing a new session to be properly deleted.
Since the 'info' subcommand also needs to process the recorded events,
add a 'display_info' flag to differentiate between report and info
commands.
Furthermore, this patch also calls perf_session__has_traces(), making
sure that we don't compare apples and oranges, fixing a segfault when
using an perf.data file generated by a different subcommand. ie:
./perf mem record sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.017 MB perf.data (~724 samples) ]
./perf lock report
Segmentation fault (core dumped)

So that we can have generic formatters that act upon specific
parameters.
Start using them with a simple string table that assumes entries
will be indexes to a string table, like with the 'which' parm
for the set and getitimer syscalls

From: David Ahern <[email protected]>
Current timestamp shown for output is time relative to firt sample. This
patch adds an option to show the absolute perf_clock timestamp which is
useful when comparing output across commands (e.g., perf-trace to
perf-script).

This way we make the output more compact.
If somebody complain (and provide a sane reason why we would like to see
zeroes) we can make it an optional, ~/.perfconfig configurable knob.

1.8.1.4
From: Davidlohr Bueso <[email protected]>
While perf-lock currently reports both the total wait time and the
number of contentions, it doesn't explicitly show the average wait time.
Having this value immediately in the report can be quite useful when
looking into performance issues.
Furthermore, allowing report to sort by averages is another handy
feature to have - and thus do not only print the value, but add it to
the lock_stat structure.

1000000+0 records in
1000000+0 records out
512000000 bytes (512 MB) copied, 0.26123 s, 2.0 GB/s
Performance counter stats for 'dd if=/dev/zero of=/dev/null count=1000000':
911,626,453 cycles # 0.000 GHz

The 0.000 GHz comment in the output is totally bogus and misleading. It
happens because update_shadow_stats() doesn't touch runtime_nsecs_stats;
it is only written when a requested counter matches a SW_TASK_CLOCK. In
our case, since we have only requested HW_CPU_CYCLES,
runtime_nsecs_stats is unavailable. So, omit printing the comment
altogether.

From: Davidlohr Bueso <[email protected]>
The report_lock_*_event() functions return -1 when lock_stat_findnew(),
thread_stat_findnew() or get_seq() return NULL. These functions only
return this value when failing to allocate memory, this return -ENOMEM
instead.

From: Namhyung Kim <[email protected]>
Currently the srcline sort key compares ip rather than srcline info. I
guess this was due to a performance reason to run external addr2line
utility. Now we have implemented the functionality inside, use the
srcline info when comparing hist entries.
Also constantly print "??:0" string for unknown srcline rather than
printing ip.

Patch adds more subtle handling of -C and -N parameters in
parse_{cpu,node}_setup_list() functions when there isn't enough NUMA
nodes or CPUs present. Instead of assertion and terminating benchmark,
partial test is skipped with error message and perf will continue to the
next one.
Fixed problem can be easily reproduced on machine with only one NUMA
node:
# Running numa/mem benchmark...
# Running main, "perf bench numa mem -a"
...
# Running RAM-bw-remote, "perf bench numa mem -p 1 -t 1 -P 1024 -C 0 -M 1 -s
perf: bench/numa.c:622: parse_setup_node_list: Assertion `!(bind_node_0 < 0 ||
bind_node_0 >= g->p.nr_nodes)' failed.

Running "perf top" on a machine with possibly invalid or non-matching
vmlinux at the various places results in no symbol resolving despite
/proc/kallsyms being present and valid.
Add a new option --ignore-vmlinux to explicitly indicate that we do not
want to use these kernels and just use what we have (kallsyms).

Some dso's lack srcline info, so there's no point to keep trying on
them. Just save failture status and skip them.

Allow the measurement of thread versus process context switch
performance.
The default stays at 'process' based measurement, like lmbench's lat_ctx
benchmark.

The strlcpy() feature check slows every build unnecessarily - so make it
a __weak function so it does not have to be auto-detected.
If the libc (or any other library) has an strlcpy() implementation it will
be used - otherwise our fallback is active.

The bash-completion package defines the _get_comp_words_by_ref function.
There is no need to depend on it, as we can reimplement it like git.git
has.

The statement
have perf
limits the locations in which to look for the perf program. Moreover,
it depends on the bash-completion package to be installed. Replace it
with a call to `type perf`.

The various testcases used different styles, which was not really
visible as long as they hid in feature-tests.mak. Now that they
are out in the open make them prettier.
( Also delete the leftover, empty feature-tests.mak file. )

_filedir is defined in the bash-completion package, but there is no need
to depend on it. Instead, call complete with multiple -o arguments
before the -F argument like in git.git's completion script.

1.8.1.4
From: Ingo Molnar <[email protected]>
The detection of certain rarely detected features can be delayed
to when they are actually needed.
So speed up the common case of auto-detection by pre-building only
a core set of features and populating only their feature-flags.
[ Features not listed in CORE_FEATURES need to built explicitly
via the feature_check() function. ]
(Also order the feature names alphabetically, while at it.)

Prepare to include them into test-all.c directly, by making sure
that they build cleanly and without warnings.
Also make sure they make a certain amount of sense and don't crash
when executed.

This was a long-standing bug, relative pathnames like O=dir did not fully
work in the build system:
$ make O=localdir clean
SUBDIR Documentation
../../scripts/Makefile.include:3: *** O=localdir does not exist. Stop.
make[1]: *** [clean] Error 2
make: *** [clean] Error 2
Fix this by canonizing the directory before passing it to Makefile.perf.

Change the print-out of auto-detected features by making sure that
repeat invocations of 'make' when all features are successfully
detected do not produce the (rather lengthy) autodetection printout.
( When one or more features are missing then we still print out the
feature detection table, to make sure people are aware of the
resulting limitations. )

From: Ingo Molnar <[email protected]>
David Ahern reported that when passing in LDFLAGS=-static then
the feature checks still succeed - causing build failures down
the line because the static libraries are missing.
Solve this by passing through LDFLAGS to the feature-check
Makefile.

From: Ingo Molnar <[email protected]>
Concatenate all feature checks into test-all.c.
This can be built and checked faster than all the individual tests.
If test-all fails then we still check all the individual features, so
this is a pure speedup, it should have no effects on functionality.

From: Ingo Molnar <[email protected]>
Start the split-out of the feature check code by adding a list of features to be
tested, and rules to process that list by building its matching feature-check
file in config/feature-checks/test-<feature>.c.
Add 'hello' as the initial feature.
This structure will allow us to build split-out feature checks in parallel and
thus speed up feature detection dramatically.
No change in functionality: no feature check is used by the build rules yet.

From: Ingo Molnar <[email protected]>
Use GCC's -MD feature to generate a dependency file for each feature test .c file,
and include that .d file in the config/feature-checks/Makefile.
This allows us to do two things:
- speed up feature tests
- detect removal or changes in build dependencies - including system libraries/headers
