To do this it also has to extractthe vreg->physreg copies that set up the call's arguments, since if it doesn'tthen the call inst ends up using undefined physregs in it's new spliced block.SelectionDAG implementations can do this because they delay emitting registercopies until *after* the stack arguments are set up. GISel however justprocesses and emits the arguments in IR order, so stack arguments always end uplast, and thus this breaks the code that looks for any register arg copies thatprecede the call instruction.This patch adds a thunk argument to the assignValueToReg() and custom assignmenthooks. For outgoing arguments, register assignments use this return param toreturn a thunk that does the actual generating of the copies. We collect theseuntil all the outgoing stack assignments have been done and then execute them,so that the copies (and perhaps some artifacts like G_SEXTs) are placed afterany stores.Differential Revision: https://reviews.llvm.org/D110610 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/Mips/GlobalISel/irtranslator/stack_args.ll Mon, 27 Sep 2021 06:20:46 +0000 Amara Emerson <amara@apple.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/Mips/GlobalISel/irtranslator/stack_args.ll#acd13994 [GlobalISel] Re-generate some call lowering tests with the new CHECK-NEXT behaviour.

This should be removed in the near future (I think Iconverted all of the tests already, but likely missed a few).Not sure what the exact syntax and policy should be. We can continueprinting the number of bytes for non-generic instructions to avoidtest churn and only allow non-scalar types for generic instructions.This will currently print the LLT in parentheses, but accept parsingthe existing integers and implicitly converting to scalar. Theparentheses are a bit ugly, but the parser logic seems unable to dealwithout either parentheses or some keyword to indicate the start of atype.
