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 [
