------- Comment #49 from sherpya at netfarm dot it 2008-10-07 12:15 ------- not exactly, Simon Sasburg compiled with -march=core2 I'm not explicitly telling to gcc to compile sse code, arch is i686 and opt is -O2 so there is no sse code generated by gcc, ffmpeg declares aligned vars in fft.c and uses them in asm sse code, file fft_mmx.asm that is generated by yasm
so gcc is unable to known that those vars will be used by sse code, this case will not covered by the last patch gcc should emit a warning when compiling align declared vars on win32 version 3.x had a similar warning but only if using align > 16 with current state of compiler/toolchain even 16-bytes aligned is not possible without explicit -fno-common compile switch -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216
