AFAICT the syntax for dg-require-ifunc seems to be
/* { dg-require-ifunc "" } */
with two sets of exceptions:
(1) gcc.target/i386/pr90500-*.c
which explains
FAIL: gcc.target/i386/pr90500-1.c (test for errors, line 6)
FAIL: gcc.target/i386/pr90500-1.c (test for warnings, line 6)
FAIL: gcc.target/i386/pr90500-1.c (test for excess errors)
FAIL: gcc.target/i386/pr90500-2.c (test for errors, line 6)
FAIL: gcc.target/i386/pr90500-2.c (test for warnings, line 6)
FAIL: gcc.target/i386/pr90500-2.c (test for excess errors)
and is fixed with the trivial patch

(2) gcc.target/i386/pr84723-*.c
which succeed on darwin. What is the suitable fix for that?
(a) Fix the dg-require-ifunc as above?
(b) Remove the line?
TIA
