Hi, I am in the process of porting our target to GlobalISel, and have encountered a problem. Nearly all instructions in our instruction set make modifications to a CC register, and hence are defined as follows: let ..., Defs = [CCReg] in def shfts_a32_imm7: Instruction<(outs OurRC:$dst), ...>; What's more, many of these instructions have patterns where the instruction itself

Hi all, first of all thanks to Matt for hosting the round table yesterday and to everyone else for their time and the valuable discussions. As promised in the chat yesterday, here is the email regarding the legalizer / artifact combiner issue we talked about. I will send a separate email regarding the regbankselect discussion. In case someone on the list didn't attend the round table

Hi all, this is the second email for the round table follow-up, this time regarding the issues around the greedy RegBankSelect and alternative mappings. The issue I brought up was that because RegBankSelect goes top-down, it never looks at all available mappings for the operands when considering which of the mappings to apply to the current instruction. In our architecture we have one

Sorry if I wasn't clear about my use case. In my daily dev work, I do many local "ninja check"s, or "llvm-lit" on a subdirectory as a quick(er) smoke test if I am making changes in that area (e.g. "llvm-lit ../llvm/test/CodeGen"). Nothing wrong here, as indeed nothing changed here. But in case of a test failure, I want to run just that test: bin/llvm-lit
