Hello guys, Thanks for your help when you are busing. I am working on an open source project. It supports shader language and I want JIT feature, so LLVM is used. But now I find the ABI & Calling Convention did not co-work with MSVC. For example, following code I have: struct float4 { float x, y, z, w; }; struct float4x4 { float4 x, y, z, w; }; float4 fetch_vs( float4x4* mat

Hi, I found that llvm.exp.f32 didn't work but sqrt works well. I implemented a function like define inlinehint float "my_exp"(float %.value) { .body: %0 = call float @llvm.exp.f32(float %.value) ret float %0 } declare float @llvm.exp.f32(float) nounwind readonly But it generates following ASM: 00280072 movups xmm0,xmmword ptr [esp+8] 00280077 movss dword ptr

Hi Guys, I found that FRem generates instruction *call 0* by JIT on windows 7, msvc 2010 sp1 x86, and llvm.exp.f32 also has this issue. My LLVM version is official 3.0. Anyone give me some tips ?

Hi guys, Does getPointerSizeInBits need to return sizeof(void*) in Platform? I found that getPointerSizeInBits return 8 in x86-32 on win7-64, MSVC 2010. And if I have a struct { i32, i32* }; the structLayout->getElementOffset(1) return 8, but I think 4 is right. In generated ASM, the offset of second element is 4.
