Fixed like this:
Index: gcc/optabs.c
===================================================================
--- gcc/optabs.c (branch cond-optab)
+++ gcc/optabs.c (working copy)
@@ -4026,6 +4026,8 @@ prepare_cmp_insn (rtx x, rtx y, enum rtx
/* Don't let both operands fail to indicate the mode. */
if (GET_MODE (x) == VOIDmode && GET_MODE (y) == VOIDmode)
x = force_reg (mode, x);
+ if (mode == VOIDmode)
+ mode = GET_MODE (x) == VOIDmode ? GET_MODE (x) : GET_MODE (y);
/* Handle all BLKmode compares. */
... which I'll commit in a few hours to cond-optab branch.
Thanks!
