I assume you meant ST_REG_P instead of ST_REGNO_P and it looks like
ST_REG_P wants a register number as an argument so the patch I tested
and checked in is:
diff --git a/gcc/config/mips/mips.c b/gcc/config/mips/mips.c
index 617391c..ff28750 100644
--- a/gcc/config/mips/mips.c
+++ b/gcc/config/mips/mips.c
@@ -8184,7 +8184,7 @@ mips_print_operand (FILE *file, rtx op, int letter)
case 't':
{
int truth = (code == NE) == (letter == 'T');
- fputc ("zfnt"[truth * 2 + (GET_MODE (op) == CCmode)], file);
+ fputc ("zfnt"[truth * 2 + ST_REG_P (REGNO (XEXP (op, 0)))], file);
}
break;
If no issues come up over the weekend with this patch I will backport it
to the 4.8 branch next week.
