From 5b2a69fa143a3164437a77df692e558c69485d2a Mon Sep 17 00:00:00 2001 From: rsandifo Date: Tue, 19 Jul 2011 17:43:15 +0000 Subject: gcc/ * doc/rtl.texi (MEM_SIZE_KNOWN_P): Document. (MEM_SIZE): Change from returning an rtx to returning a HOST_WIDE_INT. * rtl.h (MEM_SIZE_KNOWN_P): New macro. (MEM_SIZE): Return a HOST_WIDE_INT rather than an rtx. * emit-rtl.h (set_mem_size): Take a HOST_WIDE_INT rather than an rtx. (clear_mem_size): Declare. * emit-rtl.c (set_mem_size): Take a HOST_WIDE_INT rather than an rtx. (clear_mem_size): New function. * alias.c (ao_ref_from_mem): Adjust uses of MEM_SIZE, using MEM_SIZE_KNOWN_P to test whether the size is known, and MEM_SIZE to get a HOST_WIDE_INT size. Adjust calls to set_mem_size, passing a HOST_WIDE_INT rather than an rtx. Use clear_mem_size to clear the size. (nonoverlapping_memrefs_p): Likewise. * builtins.c (get_memory_rtx, expand_builtin_memcmp): Likewise.
