From d212107246869861689c6bbdb9117239d83d1576 Mon Sep 17 00:00:00 2001 From: bje Date: Tue, 17 Jan 2006 23:43:27 +0000 Subject: * expr.c (emit_move_change_mode): Always adjust addresses, not just during reload. Copy replacements only during reload. (emit_move_insn_1): Move MODE_DECIMAL_FLOAT modes by invoking emit_move_via_integer. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@109845 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/expr.c | 36 +++++++++++++++++++++++++----------- 1 file changed, 25 insertions(+), 11 deletions(-) (limited to 'gcc/expr.c') diff --git a/gcc/expr.c b/gcc/expr.c index 7a83b7e317f..92048ff7304 100644 --- a/gcc/expr.c +++ b/gcc/expr.c @@ -1,6 +1,7 @@ /* Convert tree expression to rtl instructions, for GNU compiler.
