"maybe no-ssse3" There are a lot of "recent" AMD cpus which don't support ssse3. cpu0: AMD Athlon(tm) II X4 638 Quad-Core Processor, 2700.26 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,MWAIT,CX16,POPCNT,NXE,MMXX,FFXSR,PAGE1GB,LONG,3DNOW2,3DNOW,LAHF,CMPLEG,SVM,EAPICSP,AMCR8,ABM,SSE4A,MASSE,3DNOWP,OSVW,IBS,SKINIT,ITSC > > > 0x06d685fb <_GLOBAL__sub_I_qguiapplication.cpp+43>: movsd > > 0x8(%esp),%xmm0 > .. > > 0x06d6860c <_GLOBAL__sub_I_qguiapplication.cpp+60>: movsd > > %xmm0,0x8(%eax) > -- Juan Francisco Cantero Hurtado http://juanfra.info
