At the moment of + instantiation the FP options may be different from the default values, + defined by command-line option. In such case FP attributes would have + unexpected values. For example, the code: + + template <class C> void func_01(int last, C) { + func_01(last, int()); + } + void func_02() { func_01(0, 1); } + #pragma STDC FENV_ACCESS ON + + caused compiler crash, because template instantiation takes place at the + end of translation unit, where pragma STDC FENV_ACCESS is in effect. As + a result, code in the template instantiation would use constrained + intrinsics while the function does not have StrictFP attribute. + + To solve this problem, FP attributes in Sema must be set to default + values, defined by command line options. + + This change resolves https://github.com/llvm/llvm-project/issues/63542. + + Differential Revision: https://reviews.llvm.org/D154359 + +diff --git clang/lib/Sema/SemaTemplateInstantiateDecl.cpp clang/lib/Sema/SemaTemplateInstantiateDecl.cpp +index 492fe8ba1b14..9e5f85b0f916 100644 +--- clang/lib/Sema/SemaTemplateInstantiateDecl.cpp ++++ clang/lib/Sema/SemaTemplateInstantiateDecl.cpp +@@ -5087,6 +5087,10 @@ void Sema::InstantiateFunctionDefinition(SourceLocation PointOfInstantiation, + // PushDeclContext because we don't have a scope. + Sema::ContextRAII savedContext(*this, Function); + ++ FPFeaturesStateRAII SavedFPFeatures(*this); ++ CurFPFeatures = FPOptions(getLangOpts()); ++ FpPragmaStack.CurrentValue = FPOptionsOverride(); ++ + if (addInstantiatedParametersToScope(Function, PatternDecl, Scope, + TemplateArgs)) + return;
