From c38bbf5eed1061634df192cf56086adc0410e7d8 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Fri, 8 Jan 2021 01:50:27 +0000 Subject: [PATCH] VAX: Use a mode with `const_double_zero' expressions For predictable semantics propagate the mode from operands referred by the FP substitution to the `const_double_zero' expressions used with the associated condition code calculation. Use an iterator to make copies of the FP substitution across the FP modes supported as the substitution now has to match the mode of the operands. gcc/ * config/vax/vax.md (subst_f): Add mode to operands and `const_double_zero'. --- gcc/config/vax/vax.md | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/gcc/config/vax/vax.md b/gcc/config/vax/vax.md index e5ab487..49d3eab 100644 --- a/gcc/config/vax/vax.md +++ b/gcc/config/vax/vax.md @@ -79,13 +79,13 @@ (match_dup 1))]) (define_subst "subst_f" - [(set (match_operand 0 "") - (match_operand 1 "")) + [(set (match_operand:VAXfp 0 "") + (match_operand:VAXfp 1 "")) (clobber (reg:CC VAX_PSL_REGNUM))] "" [(set (reg:VAXccnz VAX_PSL_REGNUM) (compare:VAXccnz (match_dup 1) - (const_double_zero))) + (const_double_zero:VAXfp))) (set (match_dup 0) (match_dup 1))]) -- 2.7.4
