<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-llvm-ir Author: Matt Arsenault (arsenm) <details> <summary>Changes</summary> This is getting pretty ugly, but seems to be the worst of the cases. Opting out of the base set of calls for the various windows cases is really ugly. We need to apply that to the arm cases as well. It also may make sense to go back to transposing the architecture and operating system (i.e. make isOSWindows the SystemLibrary and then modify based on architecture). --- Full diff: https://github.com/llvm/llvm-project/pull/148575.diff 3 Files Affected: - (modified) llvm/include/llvm/IR/RuntimeLibcalls.h (+4) - (modified) llvm/include/llvm/IR/RuntimeLibcalls.td (+83-7) - (modified) llvm/lib/IR/RuntimeLibcalls.cpp (+18-136) ``````````diff diff --git a/llvm/include/llvm/IR/RuntimeLibcalls.h b/llvm/include/llvm/IR/RuntimeLibcalls.h index 97a6389844439..c63c7cd64ec4d 100644 --- a/llvm/include/llvm/IR/RuntimeLibcalls.h +++ b/llvm/include/llvm/IR/RuntimeLibcalls.h @@ -174,6 +174,10 @@ struct RuntimeLibcallsInfo { (TT.isAndroid() && !TT.isAndroidVersionLT(9));
