Not "broken" as such. Just "new gcc warns".

Yuck. Yuck yuck yuck yuck yuck.
1. Spaces -> source bloat.
2. No tab at the start of the file -> yuck when reading the ASM.
My preferred way of fixing these in ARM stuff is to add <tab><tab><tab>\n\
to each line (with the appropriate number of tabs. See
arch/arm/kernel/semaphore.c for an example.

What do you mean by that?

Hmm... Wasn't that the behavior we wanted to fix with the concatenated
strings?

Ever tried:
make kernel/fork.s
and then read kernel/fork.s ? Yes, some people who care about getting
the best out of the kernel do convert C to assembly and then read the
result. If there's something really yucky in there, then you go back
and fix it in the C source.

"behaviour" or "style". I prefer my style for the code I maintain, which
is close to Linus' style. There is no current style for fixing gcc 3.x
stuff, so its up to the authors of the code to set the style. I've
decided on one which matches the style of my multi-line macros for
consistency sake. I'd rather not invent another style for multi-line
asm.
Sure, both "fix" the underlying problem. But how readable is it in the
end?
BTW, your sig is being messed up by the mixture of spaces and tabs:

s/C/compiler/
Or were you _really_ advocating the kind of development methodology which
gave us all those gotos to out-of-line code which gcc helpfully moved back
in-line for us when it got a little smarter because someone else observed
the same problem and fixed it _properly_?
Tweaking your code and sacrificing chickens until you happen to get the
output you want is no substitute for fixing the compiler. And it's a waste
of good chickens.

Not at all. You can sometimes sanely re-organise and optimise your C
code to produce better assembly without affecting its readability too
much.

"Fixing the compiler" for ARM would entail getting a degree in compiler
design, and rewriting GCC from scratch. GCC *really* isn't suited to
ARM CPUs at all. It sucks. The fact that earlier GCC versions sucked
less is the really interesting thing here...
GCC 3.1 is a hard compiler to find stuff wrong with (unlike previous
versions - well done gcc people!) However, here's a good example of a
bit of madvise_fixup_start, built for Xscale with a 5-stage instruction
pipeline with branch prediction.
It's from mm/filemap.c, setup_read_behaviour (inline function inside
madvise_fixup_start).
1. The C code:
VM_ClearReadHint(vma);
switch(behavior) {
case MADV_SEQUENTIAL:
vma->vm_flags |= VM_SEQ_READ;
break;
case MADV_RANDOM:
vma->vm_flags |= VM_RAND_READ;
break;
default:
break;
}
2. GCC 3.1 output with -O2 on ARM:
ldr r3, [r4, #20]
cmp r6, #1
bic r3, r3, #98304
str r7, [r4, #8]
str r3, [r4, #20]
beq .L803 <=== branch if equal
cmp r6, #2
orreq r3, r3, #32768
beq .L811 <=== branch if equal
.L806:
ldr r0, [r4, #56]
...
b .L809
.L811:
str r3, [r4, #20]
b .L806 <=== unconditional branch
.L803:
orr r3, r3, #65536
b .L811 <=== unconditional branch
This gives the following instruction path lengths:
neither: 10 (no branches)
first: 11 (3 branches)
second: 12 (2 branches)
-Os doesn't make much difference.
3. My human-based optimised output for ARM is:
ldr r3, [r4, #20]
cmp r6, #1
bic r3, r3, #98304
str r7, [r4, #8]
orreq r3, r3, #65536
beq .L806 <=== branch if equal
cmp r6, #2
orreq r3, r3, #32768
.L806:
str r3, [r4, #20]
ldr r0, [r4, #56]
...
b .L809
This gives the following instruction path lengths:
neither: 10 (no branches)
first: 8 (3 branches)
second: 10 (2 branches)
Any way you look at it, the above has got to be better.
We can probably get something very close to (3) out of gcc by doing
something like:
unsigned long flags;
flags = vma->vm_flags & ~(VM_SEQ_READ|VM_RAND_READ);
switch(behavior) {
case MADV_SEQUENTIAL:
flags |= VM_SEQ_READ;
break;
case MADV_RANDOM:
flags |= VM_RAND_READ;
break;
default:
break;
}
vma->vm_flags = flags;
No gotos required. So, what about VM_ClearReadHint()? It turns out
that its only used in once place - setup_read_behaviour(). Now, with
the above, we end up with the following output from the same version
of gcc with -O2:
ldr r3, [r4, #20]
cmp r6, #1
bic r3, r3, #98304
str r7, [r4, #8]
orreq r3, r3, #65536
beq .L801
cmp r6, #2
orreq r3, r3, #32768
.L801:
ldr r0, [r4, #56]
str r3, [r4, #20]
All I've shown above is how GCC can miss some optimisations its easy
for a human to see, and there are some simple ways to rewrite C code
to allow GCC to make those optimisations. But hey - that's nothing
new.
