--- Comment #16 from Martin Liška <marxin at gcc dot gnu.org> ---
One more problem I noticed that started with this revision:
$ cat pr48641.c
#define MODFL __builtin_modfl
void foo() {
long iptrll;
MODFL(0.5l, (long double *)&iptrll);
}
$ ./xgcc -B. pr48641.c -frounding-math -Og -fno-tree-fre
pr48641.c: In function ‘foo’:
pr48641.c:5:1: error: unrecognizable insn:

(const_double:TF 0.0 [0x0.0p+0])) "pr48641.c":4:3 -1
(nil))
during RTL pass: vregs
