(In reply to comment #3) > Does it work when compiled with -O0 instead of -O4? How about -O1? The code compiles and produces the expected result with -O1, O2, but can't be compiled with -O0: In file included from h264.c:36: cabac.h: In function 'get_cabac': cabac.h:454: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm' cabac.h:454: error: 'asm' operand has impossible constraints h264.c: In function 'decode_cabac_residual': h264.c:6120: warning: initialization from incompatible pointer type > Besies above, I noticed that the asm in get_cabac looks to be clobbering > memory > but is not marked as such. I can't really comment on that as I'm not too inline-asm fluent... however, I can say that this code can't be compiled without -fomit-frame-pointer. Is GCC supposed to produce valid code with this source to begin with? Guillaume -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29440
