[Bug target/37216] [cygming] Invalid alignment for SSE store to .comm data generated with -O3

[sherpya at netfarm dot it]

------- 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
