I tried to test on Windows. I suppose this is an _expected_ behavior. Maybe, 'r.ptr[4]' and its followings lines should be 'r.ptr[0]' and so on. Please help, SIMD expert... :) ================================================================== Reduced Code: //DMDFLAGS=-O -m64 import core.simd; alias float[8] F8; F8 simdAdd(F8 a1, F8 a2) { F8 res; float4 v1; float4 v2; float4 r; // 0..4 OK v1.array = a1[0..4]; v2.array = a2[0..4]; r = __simd(XMM.ADDPS, v1,v2); res.ptr[0] = r.ptr[0]; res.ptr[1] = r.ptr[1]; res.ptr[2] = r.ptr[2]; res.ptr[3] = r.ptr[3]; // 4..8 NG v1.array = a1[4..8]; v2.array = a2[4..8]; r = __simd(XMM.ADDPS, v1,v2); res.ptr[4] = r.ptr[4]; // Error: variable r used before set res.ptr[5] = r.ptr[5]; res.ptr[6] = r.ptr[6]; res.ptr[7] = r.ptr[7]; return res; } -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
