Control: reassign -1 src:givaro On 11/29/2016 09:58 AM, Tobias Hansen wrote:
I think I figured out at least the test failures with "Illegal instruction" on i386. The problem is that givaro is built using cpu extensions that are not allowed.Jerome figured out in [1] that the problem happens when givaro code is called. And sure enough: objdump -S /usr/lib/i386-linux-gnu/libgivaro.so.9.0.0 | grep '\b\(ymm\|zmm\|vfm\)' 15411: c4 e3 79 6b 8b a4 29 vfmaddsd %xmm2,-0x1d65c(%ebx),%xmm0,%xmm1 154d1: c4 e3 69 6b 8b ac 29 vfmaddsd %xmm0,-0x1d654(%ebx),%xmm2,%xmm1 And in the i386 build logs for givaro there are these flags: -mmmx -mpopcnt -msse -msse2 -msse3 -msse4.1 -msse4.2 -msse4a -mavx -mfma4 -mfpmath=sse Do you have time in the next days to disable these flags? Otherwise I can do it. (I'm not sure if some of these flags (mmx, sse ?) are allowed on i386 and didn't find that info. Ximin, do you know this?)
Sure, I can take a look. I think it should be a simple --disable-simd in d/rules (we did the same in fflas-ffpack).
