--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Can you try adding -fno-strict-aliasing -fwrapv ?
Next is does ffmpeg have inline-asm for the flac codec? This requires some C
code knowledge though.

And -fno-aggressive-loop-optimizations. I see the vectorizer is already turned
off.

OK, I modified the CFLAGS statement in config.mak to what is below, re-ran make
clean and make, and still experienced the same problems.
CFLAGS= -std=c99 -fomit-frame-pointer -pthread -D_GNU_SOURCE=1 -D_REENTRANT
-I/usr/include/SDL -g -Wdeclaration-after-statement -Wall
-Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wwrite-strings

-Wstrict-prototypes -Wempty-body -Wno-parentheses -Wno-switch

-fno-tree-vectorize -Werror=implicit-function-declaration
-Werror=missing-prototypes -Werror=return-type -Werror=vla
-Wno-maybe-uninitialized -fno-strict-aliasing -fwrapv
-fno-aggressive-loop-optimizations
Thanks for your interest.

PS, no assembly language in the flac decoding process as far as I could see.

All three testcases use the same inline function libavcodec/golomb.h:
314 /**
315 * read unsigned golomb rice code (jpegls).
316 */
317 static inline int get_ur_golomb_jpegls(GetBitContext *gb, int k, int limit,
318 int esc_len)
319 {
320 unsigned int buf;
321 int log;
322
323 OPEN_READER(re, gb);
324 UPDATE_CACHE(re, gb);
325 buf = GET_CACHE(re, gb);
326
327 log = av_log2(buf);
328
329 if (log - k >= 32 - MIN_CACHE_BITS + (MIN_CACHE_BITS == 32) &&
330 32 - log < limit) {
331 buf >>= log - k;
332 buf += (30 - log) << k;
333 LAST_SKIP_BITS(re, gb, 32 + k - log);
334 CLOSE_READER(re, gb);
335
336 return buf;
337 } else {
338 int i;
339 for (i = 0; i < limit && SHOW_UBITS(re, gb, 1) == 0; i++) {
340 if (gb->size_in_bits <= re_index)
341 return -1;
342 LAST_SKIP_BITS(re, gb, 1);
343 UPDATE_CACHE(re, gb);
344 }
345 SKIP_BITS(re, gb, 1);
346
347 if (i < limit - 1) {
348 if (k) {
349 buf = SHOW_UBITS(re, gb, k);
350 LAST_SKIP_BITS(re, gb, k);
351 } else {
352 buf = 0;
353 }
354
355 CLOSE_READER(re, gb);
356 return buf + (i << k);
357 } else if (i == limit - 1) {
358 buf = SHOW_UBITS(re, gb, esc_len);
359 LAST_SKIP_BITS(re, gb, esc_len);
360 CLOSE_READER(re, gb);
361
362 return buf + 1;
363 } else
364 return -1;
365 }
366 }
And indeed adding __attribute__ ((optimize(0))) to it "fixes" all three
testcases.
The function looks suspicious and I'm not sure if the code is valid.

I'm still working my way through the code, but it looks like we're mucking up
the value for "buf" and "k". Not really sure if that's the root cause is just
a downstream effect. Anyway, once the buf computation goes awry bad the
callers start to see unexpected results and the bogus errors.

--- Comment #24 from Jeffrey A. Law <law at redhat dot com> ---
So the issue here is we have an ASM which feeds an eq/neq condition found
inside a loop. The eq/neq condition creates an equivalency that is (mis) used
when we thread through the loop backedge.
The code which records temporary equivalences for jump threading ignores
GIMPLE_ASMs, so as we reprocess the block, the old equivalence isn't replaced
with anything new. ie, the old equivalence doesn't get invalidated.
As a result we re-use the implied value from the conditional in a previous
iteration of the loop to incorrectly simplify a test and all hell breaks loose.
In the past we were so conservative when traversing loop backedges that it was
safe to totally ignore GIMPLE_ASMs in this code. That's no longer the safe
thing to do.

Thanks. Another thing I've noticed is that ac3 audio doesn't work
(no sound at all) when ffmpeg is compiled by gcc-4.9. I haven't figured
it out yet, but it appears to be a different issue, because it also
happens with r205279 reverted.

Luckily this issue is already fixed on the gcc-4.9 branch.

Ah, it only happens with r205279 reverted. It could be a latent issue.
Would be good to check if it happens with your fix, too.
Could you attach your patch?

Please, don't forget to backport the fix to the 4.9 branch.
gcc 4.9.0 is almost unusable for ffmpeg because this didn't make it on time.
Thanks.

James,
The whole point behind leaving the 4.9 regression marker is to ensure this BZ
gets reviewed as part of the 4.9.1 process. I'd consider this high priority
for 4.9.1 and fully expect the fix will be included in 4.9.1.
