You could also just have approved the patch I had sent two months before: <http://mid.mail-archive.com/87fu9aiemr.fsf@euler.schwinge.homeip.net>. ;-) One remark: > --- a/gcc/testsuite/lib/target-supports.exp > +++ b/gcc/testsuite/lib/target-supports.exp > @@ -449,7 +449,7 @@ proc check_ifunc_available { } { > extern "C" { > #endif > typedef void F (void); > - F* g (void) {} > + F* g (void) { return 0; } > void f () __attribute__ ((ifunc ("g"))); > #ifdef __cplusplus > } Is it OK to "return 0" from this ifunc handler, or might some analysis in GCC trip over that (at some later point)? In my patch, I returned the address of an "extern" function. Grüße Thomas
