I want to generate Haskell bindings to LLVM intrinsics. In a first attempt I wrote a little parser that reads IntrinsicsX86.td and outputs a Haskell module. E.g. the definition def int_x86_avx_max_ps_256 : GCCBuiltin<"__builtin_ia32_maxps256">, Intrinsic<[llvm_v8f32_ty], [llvm_v8f32_ty, llvm_v8f32_ty], [IntrNoMem]>; is turned into maxpd256 :: Ext.T (V4Double -&...

Hello，everyone. I am very embarrassed to ask such a simple question. I want to add an intrinsics(named max_qb) in x86 backend. In include/llvm/IR/IntrinsicsX86.td, I add a intrinsics (GCCBuiltin). In clang( BuiltinsX86.def ), I add a BUILTIN. And in x86 backend , I change : the X86InstrInfo.td to add def X86max_qb_flag , X86InstrArithmetic.td to add define of instruction , X86ISelLowering.cpp to add SDnode. It's succeed when LLVM compilates.But ther...

Where would people like me to put AVX intrinsic definitions? I could put them in the current IntrinsicsX86.td or put them in a new file. We've called it IntrinsicsX86AVX.td. We put ours in a separate file to avoid upstream conflicts but now that we're getting ready to merge our stuff up we'd like the LLVM community's opinion on where it should go. Thanks....

Hello, I have a problem with pattern matching on intrinsics. I have following code in IntrinsicsX86.td: ``` let TargetPrefix = "x86" in { // All intrinsics start with "llvm.x86.". def int_x86_mpx_bndmk: Intrinsic<[llvm_x86bnd_ty], [llvm_ptr_ty, llvm_i64_ty], []>; } ``` And following instruction that is generated when @llvm.x86.mpx.bndmk is used in code: ``...

...something > similar. Sure, this works. This is exactly the idea of the builtin functions in GCC. For example, in SSE, the __builtin_ia32_movntps function does a nontemporal store. To answer David's question, we already have direct support for this in tblgen, for example, include/llvm/IntrinsicsX86.td contains: let TargetPrefix = "x86" in { // All intrinsics start with "llvm.x86.". def int_x86_sse_movnt_ps : GCCBuiltin<"__builtin_ia32_movntps">, Intrinsic<[llvm_void_ty, llvm_ptr_ty, llvm_v4f32_ty], [IntrWrite...

Hi, I was talking with aKor in #llvm how we could implement custom operation support for our ASIP architecture. We came into solution that the best way would be to write new custom operation intrinsic and optimization pass for raising certain type of function calls to those intrinsics (similar to raising mallocs). Basically our custom operation are like calls, with operand name and multiple

Hey, I am currently forced to create the BLENDVPS intrinsic as an external call (via Intrinsic::x86_sse41_blendvps) which has the following signature (from IntrinsicsX86.td): def int_x86_sse41_blendvps : GCCBuiltin<"__builtin_ia32_blendvps">, Intrinsic<[llvm_v4f32_ty],[llvm_v4f32_ty, llvm_v4f32_ty, llvm_v4f32_ty],[IntrNoMem]> Thus, it expects the mask (first operand if i recall correctly) to be a <4 x float>. It would be great to hav...

...ng half precision floating point numbers and I'm a bit confused as to why certain types were chosen. I've gone ahead and used their current definition with success but I'd like to understand why the types used with these intrinsics are done this way. For reference see ``include/llvm/IR/IntrinsicsX86.td``. Here are the intrinsics of interest. ``` let TargetPrefix = "x86" in { // All intrinsics start with "llvm.x86.". def int_x86_vcvtph2ps_128 : GCCBuiltin<"__builtin_ia32_vcvtph2ps">, Intrinsic<[llvm_v4f32_ty], [llvm_v8i16_ty], [IntrNoMem]...

For example, SSE provides a broad range of intrinsics to support instructions that LLVM IR can't express well. See llvm/include/llvm/IntrinsicsX86.td for more details. If you're interested in helping shape the direction of LLVM vector support, my advice is that "patches speak louder than words" :). I'd love to see improved vector support in LLVM, but unless someone is willing to step forward and implement it, it is...

After I implemented a new type of legalization (the packing of i1 vectors), I found that x86 does not have a way to load packed masks into SSE registers. So, I guess that legalizing of <4 x i1> to <4 x i32> is the way to go. Cheers, Nadav -----Original Message----- From: Rotem, Nadav Sent: Thursday, March 10, 2011 11:04 To: 'David A.

...and I was successful with obtaining the LLVM IR. - Most of the operations were calls to external functions. - I successful JITed it for the x86 backend. - Then, I replaced the function calls by intrinsics so that I can take advantage of the LLVM optimization passes. I updated the IntrinsicsX86.td and the files concerning constant folding with this purpose. - The LLVM IR with the intrinsics looks great and benefits from all the optimization passes I was using. - Now, while Jitting to the x86 backend I got the error message "Cannot select: intrinsics %llvm.x86.my.intrinsi...

Thanks Serge! This means for every new intrinsic set, a systematic change should be made to LLVM to support the new intrinsic set, right? The change should include frontend change, IR instruction set change, as well as low level code generation changes?
