2010-08-29when merging two alias sets, the result set is volatile if eitherChris Lattner

2010-08-28I have manually decoded the imm field of an insertps one too manyChris Lattner
times. This patch causes llc and llvm-mc (which both default to verbose-asm) to print out comments after a few common shuffle instructions which indicates the shuffle mask, e.g.: insertps $113, %xmm3, %xmm0 ## xmm0 = zero,xmm0[1,2],xmm3[1] unpcklps %xmm1, %xmm0 ## xmm0 = xmm0[0],xmm1[0],xmm0[1],xmm1[1] pshufd $1, %xmm1, %xmm1 ## xmm1 = xmm1[1,0,0,0] This is carefully factored to keep the information extraction (of the shuffle mask) separate from the printing logic. I plan to move the extraction part out somewhere else at some point for other parts of the x86 backend that want to introspect on the behavior of shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112387 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-28fix the BuildVector -> unpcklps logic to not do pointless shuffles Chris Lattner
when the top elements of a vector are undefined. This happens all the time for X86-64 ABI stuff because only the low 2 elements of a 4 element vector are defined. For example, on: _Complex float f32(_Complex float A, _Complex float B) { return A+B; } We used to produce (with SSE2, SSE4.1+ uses insertps): _f32: ## @f32 movdqa %xmm0, %xmm2 addss %xmm1, %xmm2 pshufd $16, %xmm2, %xmm2 pshufd $1, %xmm1, %xmm1 pshufd $1, %xmm0, %xmm0 addss %xmm1, %xmm0 pshufd $16, %xmm0, %xmm1 movdqa %xmm2, %xmm0 unpcklps %xmm1, %xmm0 ret We now produce: _f32: ## @f32 movdqa %xmm0, %xmm2 addss %xmm1, %xmm2 pshufd $1, %xmm1, %xmm1 pshufd $1, %xmm0, %xmm3 addss %xmm1, %xmm3 movaps %xmm2, %xmm0 unpcklps %xmm3, %xmm0 ret This implements rdar://8368414 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112378 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-28Don't cast Win32 FILETIME structs to int64. Patch by Dimitry Andric!Michael J. Spencer
According to the Microsoft documentation here: http://msdn.microsoft.com/en-us/library/ms724284%28VS.85%29.aspx this cast used in lib/System/Win32/Path.inc: __int64 ft = *reinterpret_cast<__int64*>(&fi.ftLastWriteTime); should not be done. The documentation says: "Do not cast a pointer to a FILETIME structure to either a ULARGE_INTEGER* or __int64* value because it can cause alignment faults on 64-bit Windows." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112376 91177308-0d34-0410-b5e6-96231b3b80d8
