From 00c79232abd8b6bb1142b5aba51109075e780034 Mon Sep 17 00:00:00 2001 From: Marc Lehmann Date: Wed, 11 Feb 1998 00:29:57 +0000 Subject: [PATCH] i386.c: Added include for recog.h. * i386.c: Added include for recog.h. (override_options): Removed unused variable p. Initialized regno to avoid warning. (order_regs_for_local_alloc): Initialized regno to avoid warning. (legitimize_address): Likewise for 'other'. (i386_aligned_reg_p): Added default case with abort (). (print_operand): Likewise. (reg_mentioned_in_mem): Likewise. (ix86_expand_binary_operator): Removed unused variables i & insn. (ix86_expand_unary_operator): Removed unused variable insn. (output_fp_cc0_set): Removed unused variable unordered_label.
