[x264-devel] Re: x86 + yasm + pic causes x264 to segfault in x264_pixel_ssim_4x4x2_core_sse2

[Alexis Ballier]

Ha, and I hope some (perhaps) more useful info : 


I used objdump to get the code of pixel-sse2.o, and here is what I
get : 

compiled with nasm : 

2e05:       8b 44 24 18             mov    0x18(%esp),%eax
2e09:       e8 00 00 00 00          call   2e0e <x264_pixel_ssim_4x4x2_core_sse2+0x10e> 
2e0e:	    5b                      pop    %ebx 
2e0f:       81 c3 03 00 00 00       add    $0x3,%ebx 
2e15:       66 0f 6f bb 00 00 00    movdqa 0x0(%ebx),%xmm7 
2e1c:       00
2e1d:       66 0f 70 eb b1          pshufd $0xb1,%xmm3,%xmm5


and with yasm :

45e5:       8b 44 24 18             mov    0x18(%esp),%eax
45e9:       e8 00 00 00 00          call   45ee <x264_pixel_ssim_4x4x2_core_sse2+0x10e> 
45ee:       5b                      pop    %ebx 
45ef:       81 c3 12 ba ff ff       add    $0xffffba12,%ebx 
45f5:       66 0f 6f bb 00 00 00    movdqa 0x0(%ebx),%xmm7 
45fc:       00
45fd:       66 0f 70 eb b1          pshufd $0xb1,%xmm3,%xmm5
