But the forwarders - were not marked as compatibility symbols. As a result, on older - architectures, historic configure checks such as - - AC_CHECK_LIB(rt, clock_gettime) - - still cause linking against librt, even though this is completely - unnecessary. It also creates a needless porting hazard because - architectures behave differently when it comes to symbol availability. - - Reviewed-by: Carlos O'Donell <carlos@redhat.com> - -diff --git a/rt/clock-compat.c b/rt/clock-compat.c -index f816973c05..11e71aa890 100644 ---- a/rt/clock-compat.c -+++ b/rt/clock-compat.c -@@ -30,14 +30,16 @@ - #if HAVE_IFUNC - # undef INIT_ARCH - # define INIT_ARCH() --# define COMPAT_REDIRECT(name, proto, arglist) libc_ifunc (name, &__##name) -+# define COMPAT_REDIRECT(name, proto, arglist) libc_ifunc (name, &__##name) \ -+ compat_symbol (librt, name, name, GLIBC_2_2); - #else - # define COMPAT_REDIRECT(name, proto, arglist) \ - int \ - name proto \ - { \ - return __##name arglist; \ -- } -+ } \ -+ compat_symbol (librt, name, name, GLIBC_2_2); - #endif - - COMPAT_REDIRECT (clock_getres, |
