<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: None (DanilaZhebryakov) <details> <summary>Changes</summary> soft float ABI selection was not taking effect on little-endian powerPC with embedded vectors (e.g. e500v2) leading to errors. (embedded vectors use "extended" GPRs to store floating-point values, and this caused issues with variadic arguments assuming dedicated floating-point registers with hard-float ABI) --- Full diff: https://github.com/llvm/llvm-project/pull/154773.diff 1 Files Affected: - (modified) clang/lib/CodeGen/CodeGenModule.cpp (+2-1) ``````````diff diff --git a/clang/lib/CodeGen/CodeGenModule.cpp b/clang/lib/CodeGen/CodeGenModule.cpp index 677d8bc82cb0a..8b85b93b5d568 100644 --- a/clang/lib/CodeGen/CodeGenModule.cpp +++ b/clang/lib/CodeGen/CodeGenModule.cpp @@ -188,7 +188,8 @@ createTargetCodeGenInfo(CodeGenModule &CGM) { return createPPC32TargetCodeGenInfo(CGM, IsSoftFloat); } case llvm::Triple::ppcle: { - bool IsSoftFloat = CodeGenOpts.FloatABI == "soft"; + bool IsSoftFloat = + CodeGenOpts.FloatABI == "soft" || Target.hasFeature("spe"); return createPPC32TargetCodeGenInfo(CGM, IsSoftFloat); } case llvm::Triple::ppc64: `````````` </details> https://github.com/llvm/llvm-project/pull/154773 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
