Help: How to define vector element type bool (v8i1) in C builtin function hello everyone,I have defined intrinsic function like this: def int_mips_add_32 : GCCBuiltin<"__builtin_dongxin_add_32">, Intrinsic<[llvm_v4i32_ty], [llvm_v4i32_ty, llvm_v4i32_ty,llvm_v8i1_ty]>; Then I write a test code : typedef int v4i32 __attribute__ ((vector_size(16))); typedef bool v8i1

We are syncing to 2.9 and we are hitting an with our backend in VerifySDNode in SelectionDAG.cpp. The first assert here is failing assert(!isa<MemSDNode>(N) && "Bad MemSDNode!"); Now, this is new to 2.9 and I am trying to understand what is invalid about what I am generating. What I generate has worked fine from LLVM version 2.4 until now without causing any issues.

GCCBuiltin just gives it a name for clang to lookup. Generally they match up with builtins that gcc also implements, but that's not a requirement. If you add a builtin with the same name to the builtin file in clang's include/clang/Basic/Builtins*.def then they will find each other. You can also just add a builtin to clang's builtin file and catch it in clang's

I've created an intrinsic from my target, but I can't figure out how I can run it from a C code. Most of the targets have a GCCBuiltin and it looks like it is the way to execute an intrinsic from C code. However in my case there is no actual GCC built in. Any help on this is really appreciated. -- Rail Shafigulin Software Engineer Esencia Technologies -------------- next part

Hi all, I was wondering how to use variations of intrinsic functions that take a memory operand. Take for example the SSE4.1 pmovsxbd instruction. One variant takes two XMM registers, while another has a 32-bit memory location as source operand. The latter is quite interesting if you know you're reading from memory anyway, and if it's not 16-byte aligned. It looks like LLVM's
