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

Immediate operand for vector instructions

Yeah, you actually want to use "imm":
list<dag> Pattern = [(int_repeat_x_times imm:$imm)];

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 [

Immediate operand for vector instructions
...mLeaf Addr = immLeaf,
InstrItinClass itin = NoItinerary> {
dag OutOperandList = (outs);
dag InOperandList = (ins MemOpnd:$addrdst);
string AsmString = "REPEAT_X_TIMES($addrdst );";
list<dag> Pattern = [(int_connex_repeat_x_times Addr:$addrdst)];
InstrItinClass Itinerary = itin;
}
So, is there are way to use immediate values that are not memory operands?
Thank you ,
Alex
