URL: https://github.com/llvm/llvm-project/commit/d572c4cdef4b3a2b1f57769233f33a1788f5172e DIFF: https://github.com/llvm/llvm-project/commit/d572c4cdef4b3a2b1f57769233f33a1788f5172e.diff LOG: [PowerPC] Disable float128 on AIX in Clang (#67298) PowerPC AIX backend does not support float128 at all. Diagnose even when specifying -mfloat128 to avoid backend crash. --------- Co-authored-by: Kai Luo <gluo...@gmail.com> Added: Modified: clang/lib/Basic/Targets/PPC.cpp clang/test/Sema/128bitfloat.cpp Removed: ################################################################################ diff --git a/clang/lib/Basic/Targets/PPC.cpp b/clang/lib/Basic/Targets/PPC.cpp index 5ce276e1af9ef64..045c273f03c7a0c 100644 --- a/clang/lib/Basic/Targets/PPC.cpp +++ b/clang/lib/Basic/Targets/PPC.cpp @@ -53,7 +53,7 @@ bool PPCTargetInfo::handleTargetFeatures(std::vector<std::string> &Features, } else if (Feature == "+htm") { HasHTM = true; } else if (Feature == "+float128") { - HasFloat128 = true; + HasFloat128 = !getTriple().isOSAIX(); } else if (Feature == "+power9-vector") { HasP9Vector = true; } else if (Feature == "+power10-vector") { diff --git a/clang/test/Sema/128bitfloat.cpp b/clang/test/Sema/128bitfloat.cpp index b98b42496e8db27..bd9f2889c98f6aa 100644 --- a/clang/test/Sema/128bitfloat.cpp +++ b/clang/test/Sema/128bitfloat.cpp @@ -1,6 +1,7 @@ // RUN: %clang_cc1 -verify -std=gnu++11 %s // RUN: %clang_cc1 -verify -std=c++11 %s // RUN: %clang_cc1 -triple powerpc64-linux -verify -std=c++11 %s +// RUN: %clang_cc1 -triple powerpc64-ibm-aix -target-feature +float128 -verify -std=c++11 %s // RUN: %clang_cc1 -triple i686-windows-gnu -verify -std=c++11 %s // RUN: %clang_cc1 -triple x86_64-windows-gnu -verify -std=c++11 %s // RUN: %clang_cc1 -triple x86_64-windows-msvc -verify -std=c++11 %s _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
