could you please rebase this on Arnaldo's latest perf/core branch?

Odd, I can't reproduce that...
Mind sending your gcc version + the output of make V=1 + the contents
of the .cmd file causing the error?
Thanks,

ok, reproduced..
the commit changes the output of the depfile for some reason,
and our fixdep does not handle it correctly and produce wrong
cmd file that failed to parse.. checking for fix
depfile changes ('+' is after the change):
-plugin_jbd2.o: plugin_jbd2.c /usr/include/stdc-predef.h \

so Fedora 25 puts old target name in the generated dependencies
in case you split the -Wp options.. while Fedora 24 the old way
and both F24 and F25 shows me same gcc version 6.2.1
(note that just the first command output with 2 targets is wrong for us)

I'll make fixdep to deal with that and try to have someone from gcc to clarify on this

how about following fix.. it gets rid of the -Wp,MT option completely
so it should address Peter's issue.. it also makes fixdep more robust
and makes it wait for first target before spitting out dependencies
I have some difficulties now with getting Fedora 25.. I'll test
and send this out within this week

Ok, just tested, Peter's patch works if I remove ccache, with your patch
replacing it, everything works, with and without ccache, on f25, and it
builds on f24 without ccache, in one of the containers I have.

ok, so v3 actually ;-)
the v2 was tricky for the case when fixdep is not available,
so I decided to go with Peter's fix and fixing 'fixdep' tool
to properly parse out the target in case we hit the ccache
error.. we need to be able to do it anyway
please apply this patch before Peter's so we keep clean bisect
thanks,

The fixdep tool among other things replaces the target of
the object in the gcc generated dependency output file.
The parsing code assumes there's only single target in the
rule but this is not always the case as described in here:
https://gcc.gnu.org/ml/gcc-help/2016-11/msg00099.html
Making the fixdep code smart enough to skip all the possible
targets.

Doesn't work with ccache installed, but then after reinstalling ccache to check
its version, I can't reproduce it anymore, go figure :-\
Can you guys please take a look at tmp.perf/fixdep in my tree and check that
the last two patches are the ones that should go upstream and that you are able
to build it _with_ ccache installed?
Thanks,

I think this is unrelated.. I think we're missing jevents fixdep dependency
I'll test patch below and send it separately

So I saw it again, while processing Wang's eBPF/llvm patchkit, right after
removing the build dir and starting from scratch, doing that process one more
time made it work, so it looks like a race, and look it is in a HOSTCC bit,
related?

tools build: Make fixdep parsing wait for last target
The fixdep tool, among other things, replaces the target of the object
in the gcc generated dependency output file.
The parsing code assumes there's only single target in the rule but this
is not always the case as described in here:
https://gcc.gnu.org/ml/gcc-help/2016-11/msg00099.html
Make the fixdep code smart enough to skip all the possible targets.
