...tablegen but am having some issues. So LLVM doesn't seem to accept a floating point constant literal match like: %v = call <4 x float> @foo(i32 15, float %s, float 0.0, <8 x i32> %rsrc, <4 x i32> %samp, i1 0, i32 0, i32 0) ret <4 x float> %v def : XXXPat<(v4f32 (int_foo i32:$mask, f32:$s, 0, v8i32:$rsrc, v4i32:$sampler, i1:$unorm, 0, i32:$cachepolicy)), (FOO_MI (COPY_TO_REGCLASS ?:$s, 32RegClass), ?:$rsrc, ?:$sampler, (as_i32imm ?:$mask), (as_i1imm ?:$unorm), (as_i1imm ?:$cachepolicy), (as_i1imm ?:$cachepolicy), 0, 0, 0, { 0 })>; which would be ideal. This see...

Hi, All, I want to add one intrinsic function for my particular backend. Let's say the intrinsic function is named "foo" which takes two i32 inputs and has one i32 output. First, I add this line "def int_foo : Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty], [IntrReadArgMem]>;" in /include/llvm/IR/Intrinsics.td. Then, in my target/InstrInfo.td, I'm supposed to add one pattern to match this intrinsic function. However, I don't understand how LLVM can tell the difference between t...

Hi, All, Suppose I define one memory read only intrinsic function "foo" in Intrinsics.td like this def int_foo : Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty], [IntrReadMem]>; Suppose I have the following IR, which means the intrinsic function "foo" is called 10 times in a loop. Since the parameters of function "foo" are invariant and the function "foo" is defined...
