OptLevelChanger captures theoptimization level with the parameter, and rather not the valuewithin `TargetMachine`. This lets the optimization beunintentionally overwriten if other value than `CodeGenOpt::Default`passed.This patch fixes this by passing the optimization level ratherthan using the default value.Reviewed By: craig.topperDifferential Revision: https://reviews.llvm.org/D126641 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/RISCV/isel-optnone.ll Mon, 30 May 2022 12:06:48 +0000 eopXD <eop.chen@sifive.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/RISCV/isel-optnone.ll#51002bdb [RISCV] Precommit test case to show bug in RISCVISelDagToDagThe optimization level should not be restored into O2.This is a pre-commit test case to show fix in D126641.Reviewed By: craig.topperDifferential Revision: https://reviews.llvm.org/D126677 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/RISCV/isel-optnone.ll Mon, 30 May 2022 20:40:06 +0000 eopXD <eop.chen@sifive.com>
