Adding an trinsics in x86
...ryone！
I am a newbie at llvm. So the question may be fundamental but difficult to me.
I want to add an trinsics in x86 and make the following changes.I want that max_qb can find the max of two Integers and return it.
In src/include/llvm/IR/Intrinsics.td :
let TargetPrefix = "x86" in {
def int_x86_max_qb: GCCBuiltin<"__builtin_x86_max_qb">,
Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty], [IntrNoMem]>;
}
In src//tools/clang/include/clang/Basic/BuiltinsX86.def
TARGET_BUILTIN(__builtin_x86_max_qb, "V2iV2iV2i", "ncV:64:", "") //I don't know t...

how to add a instruction
Hi,every one.
I' in trouble again.
I want add a new intrinsic mapping a new instruction.
I add the int_x86_max_qb as fllowing:
def int_x86_max_qb: GCCBuiltin<"__builtin_x86_max_qb">, Intrinsic<[llvm_i32_ty], [llvm_i32_ty, llvm_i32_ty], [Commutative]>;
BUILTIN(__builtin_x86_max_qb, "iii", "")
I define the intrinsic as Pseudo instruction,it succeed.
But when mappi...

Fw: How to define an instruction
...%0 = load i32, i32* %a, align 4
%1 = load i32, i32* %b, align 4
%2 = call i32 @llvm.x86.max.qb(i32 %1, i32 %2)
store i32 %2, i32* %a, align 4
when lli test.ll ,it goes wrong.
Here is my all code:
