--- Comment #7 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The test gcc.dg/pr81854.c fails on darwin

/opt/gcc/_clean/gcc/testsuite/gcc.dg/pr81854.c:30:1: error: ifunc is not
supported in this configuration
 f3 (void);          /* { dg-error ".ifunc. resolver must return a function
pointer" } */

I think a line

/* { dg-require-ifunc "" } */

is missing.
