For GCN, this avoids ICEs further down the compilation pipeline. For nvptx, there's effectively no change: in presence of exception handling constructs, instead of 'sorry, unimplemented: target cannot support nonlocal goto', we now emit 'sorry, unimplemented: exception handling not supported'. Additionally, turn test cases into UNSUPPORTED if running into 'sorry, unimplemented: exception handling not supported'. gcc/ * config/gcn/gcn.md (exception_receiver): 'define_expand'. * config/nvptx/nvptx.md (exception_receiver): Likewise. gcc/testsuite/ * lib/gcc-dg.exp (gcc-dg-prune): Turn 'sorry, unimplemented: exception handling not supported' into UNSUPPORTED. * gcc.dg/pr104464.c: Remove GCN XFAIL. libstdc++-v3/ * testsuite/lib/prune.exp (libstdc++-dg-prune): Turn 'sorry, unimplemented: exception handling not supported' into UNSUPPORTED.
