I have this intrinsic definition for llvm. def int_opencl_math_fdistance_fast : Intrinsic<[llvm_float_ty], [llvm_anyfloat_ty, LLVMMatchType<0>]>; Can someone explain what LLVMMatchType does and how to specify it to match the first argument and not the return value? I've tried LLVMMatchType<1> but it fails in IntrinsicEmitter.cpp Thanks, -------------- next part -------------- An HTML attachment was...

Oops. That was premature. I think your original question was on the right track. TableGen distinguishes between known and "overloaded" types (like "llvm_anyfloat_ty" in your example). The overloaded types are numbered separately, and the argument to LLVMMatchType is an index into these overloaded types, ignoring the known types. So, in your case, the first argument is the first overloaded type, so you should use LLVMMatchType<0> to refer to it. On Apr 15, 2009, at 10:31 AM, Bob Wilson wrote: > That's a bug.

Hi all, I'm proposing integer saturation intrinsics. def int_ssat : Intrinsic<[llvm_anyint_ty], [LLVMMatchType<0>, llvm_i32_ty]>; def int_usat : Intrinsic<[llvm_anyint_ty], [LLVMMatchType<0>, llvm_i32_ty]>; The first operand is the integer value being saturated, and second is the saturation bit position. For scalar integer types, the semantics are: int_ssat: x < -(1 << (bit...

..., .s32, .s64 }; The presence of multiple types requires llvm.ptx.max to be overloaded for i16, i32 and i64. So I think that the right way to define the intrinsic would be (as in the attached max_not_working.patch file): def int_ptx_max : Intrinsic<[llvm_anyint_ty], [LLVMMatchType<0>, LLVMMatchType<0>], [Commutative]>; The problem is that the builtin is not recognised in the following test case: define ptx_device i16 @max_16(i16 %a, i16 %b) { entry: %d = call i16 @llvm.ptx.max(i16 %a, i16 %b) ret i16 %d } declare i16 @llvm.pt...

I'm working on intrinsics for my backend and require intrinsic overloading. Is this supported? If so, are there any examples?

Alberto, The AMDIL backend solves your problem with intrinsic overloading this way: def int_AMDIL_mad : GCCBuiltin<"__amdil_mad">, TernaryIntFloat; Where TernaryIntFloat is defined as: class TernaryIntFloat : Intrinsic<[llvm_anyfloat_ty], [LLVMMatchType<0>, LLVMMatchType<0>, LLVMMatchType<0>], []>; This allows us to write a multi-def for int_AMDIL_mad like so: defm MAD : TernaryIntrinsicFloat<IL_OP_MAD, int_AMDIL_mad>; Where TernaryIntrinsicFloat is defined as: multiclass TernaryIntrinsicFloat<ILOpCode o...

Intrinsic function llvm.guard.load.p0i32 is defined as follows: let Properties = [IntrNoMem, NoCapture<0>] in { def int_guard_load : Intrinsic<[llvm_anyptr_ty], [LLVMMatchType<0>]> } Thanks a lot.
