From 2a1a3cd51f8bb928fe7291d8dcb84492bc49f6ed Mon Sep 17 00:00:00 2001 From: Jakub Jelinek Date: Tue, 14 Dec 2004 18:59:36 +0100 Subject: [PATCH] fold-const.c (fold_single_bit_test): If flag_syntax_only, pretend LOAD_EXTEND_OP is not defined. * fold-const.c (fold_single_bit_test): If flag_syntax_only, pretend LOAD_EXTEND_OP is not defined. (fold): Likewise. If flag_syntax_only, don't depend on BITS_PER_WORD.
