Created attachment 580351 [details] reduced testcase that exposes the issue See attachment for a testcase that can run in the shell Bug is most likely due to float4 inlining Expected results: 2,0,0,0 0,3,0,0 0,0,0.4000000059604645,0 0,0,0,1 Actual results: 2,0,0,0 0,3,0,0 0,3,0,0 0,0,0,1
Root cause appers to be CSE for LIR_ffff2f4
Not CSE afterall (even though it worked with -Dnocse), but improper code generation in Nativei386 (which was copied to NativeX64 too).
