The reason for this is that the function declaration is replaced by a newly created dispatcher declaration, which has TREE_NOTHROW always set to 1. Instead we need to set TREE_NOTHROW to the value of the original declaration. PR ipa/106627 gcc/ChangeLog: * config/i386/i386-features.cc (ix86_get_function_versions_dispatcher): Set TREE_NOTHROW correctly for dispatcher declaration. * config/rs6000/rs6000.cc (rs6000_get_function_versions_dispatcher): Likewise. gcc/testsuite/ChangeLog: * g++.target/i386/pr106627.C: New test.
