--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> ---
One similar place where we do something similar is:
rtx
ix86_expand_builtin (tree exp, rtx target, rtx subtarget,
machine_mode mode, int ignore)
...
gcc /home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr84335.c -c
/home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr84335.c: In
function ‘foo’:
/home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr84335.c:9:10:
