[LLVMdev] codeGen, instruction write one value to the input register.
Hi Guys,
In LLVM codegen,
a typical binary operation instruction is defined something like below:
" def _rr: NVPTXInst<(outs Int1Regs:$dst), (ins Int1Regs:$a, Int1Regs:$b),
"xor.pred \t$dst, $a, $b;",
[(set Int1Regs:$dst, (OpNode Int1Regs:$a, Int1Regs:$b))]>;
“
which takes two inputs and write the result to the $dst register.
Then how to define a binary
