Bug ID: 125129
Summary: Many tests fail to link on FreeBSD
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: amd64-pc-freebsd15.0
Many gm2 tests fail to link on FreeBSD/amd64, e.g.
AIL: gm2/builtins/run/pass/testalloa.mod compilation, -g
unsuccessful link
UNRESOLVED: gm2/builtins/run/pass/testalloa.mod execution, -g (link failed)
gld-2.46:

I wonder what's going on here: gm2-gcc/m2builtins.cc has
{ "__builtin_ctanl", BT_FN_LDCOMPLEX_LDCOMPLEX, BUILT_IN_CTANL,
BUILT_IN_NORMAL, "ctanl", NULL, NULL, bf_c99_compl },
which seems to match builtins.def:
DEF_C99_COMPL_BUILTIN (BUILT_IN_CTANL, "ctanl",
BT_FN_COMPLEX_LONGDOUBLE_COMPLEX_LONGDOUBLE, ATTR_MATHFN_FPROUNDING)
FreeBSD's version of TARGET_LIBC_HAS_FUNCTION (bsd_libc_has_function in
targhooks.cc) seems to do the right thing by returning false for
function_c99_math_complex.
