LLVM IR intrinsics placeholder for strings [was Re: Back end with special loop instructions (using LLVM IR intrinsics)]
...tion time.)
More exactly, I would like to give something LIKE this in a middle-tier pass (I
haven't tried this code in LLVM):
Value *instrinsicFunc = Intrinsic::getDeclaration(M,
Intrinsic::my_intrinsic);
myIRBuilder.CreateCall(repeatFunc,
"string_that_llc_codegen_should_output_as_assembly");
So my intrinsic would be accepting a general string which will be used at codegen to
be output. I guess I would have to define it like this in a .td file:
def int_my_intrinsic : Intrinsic<[], [string], []>;...

Back end with special loop instructions
Hi Alex,
You might find it useful to look at how lib/Target/PowerPC/PPCCTRLoops.cpp works.

Back end with special loop instructions
Hello.
I'm writing a back end for my research SIMD processor that has an assembly language
that is blocked structured, with one-level loops. An example program with my assembly
language:
REPEAT_X_TIMES(Param2)
R0 = LS[offset_A];
END_REPEAT;
The LLVM code somewhat equivalent to the above ASM program is:
vector.body:
%index = phi i64 [
