If llc commandline contains -debug-only=isel, update_llc_test_checks.py will try to scrub iseloutput, otherwise, the script will fall back on default behaviour, which is try toscrub assembly output instead.The motivation of this change is to allow usage of update_llc_test_checks.py toautogenerate checks of instruction selection results. In this way, we can detecterrors at an earlier stage before the compilation goes all the way to assembly.It is an example of having some transparency for the stages between IR andassembly. These generated tests are almost like "unit tests" of isel stage.This patch only implements the initial change to differentiate isel output fromassembly output for Lanai. Other targets will not be supported for isel checkgeneration at the moment. Although adding support for it will only requireimplementing the function regex and scrubber for corresponding targets.The Lanai implementation was chosen mainly for the simplicity of demonstratingthe difference between isel checks and asm checks.This patch also do not include the implementation of function prefix, which isrequired for the generated isel checks to pass. I will put up a follow up revisionfor the function prefix change to complete isel support.Reviewed By: FlakebiDifferential Revision: https://reviews.llvm.org/D119368 List of files: /llvm-project-15.0.7/llvm/test/tools/UpdateTestChecks/update_llc_test_checks/Inputs/amdgpu_asm.ll.expected Tue, 01 Mar 2022 09:54:24 +0000 Yatao Wang <ningxinr@live.cn>
