* doc/rtl.texi (MEM_OFFSET_KNOWN_P): Document. (MEM_OFFSET): Change from returning an rtx to returning a HOST_WIDE_INT. * rtl.h (MEM_OFFSET_KNOWN_P): New macro. (MEM_OFFSET): Return a HOST_WIDE_INT rather than an rtx. * emit-rtl.h (set_mem_offset): Take a HOST_WIDE_INT rather than an rtx. (clear_mem_offset): Declare. * alias.c (ao_ref_from_mem): Adjust uses of MEM_OFFSET, using MEM_OFFSET_KNOWN_P to test whether the offset is known, and MEM_OFFSET to get a HOST_WIDE_INT offset. (nonoverlapping_memrefs_p): Likewise. Adjust calls to... (adjust_offset_for_component_ref): Take a bool "known_p" parameter and a HOST_WIDE_INT "offset" parameter. * builtins.c (get_memory_rtx): As for ao_ref_from_mem. Adjust calls to set_mem_offset, passing a HOST_WIDE_INT rather than an rtx. Use clear_mem_offset to clear the offset. * cfgcleanup.c (merge_memattrs): Likewise. * dwarf2out.c (tls_mem_loc_descriptor): Likewise. * function.c (assign_parm_find_stack_rtl): Likewise. (assign_parm_setup_stack): Likewise. * print-rtl.c (print_rtx): Likewise. * reload.c (find_reloads_subreg_address): Likewise. * simplify-rtx.c (delegitimize_mem_from_attrs): Likewise. * var-tracking.c (INT_MEM_OFFSET): Likewise. * emit-rtl.c (set_reg_attrs_from_value): Likewise. (get_mem_align_offset): Likewise. (set_mem_offset): Take a HOST_WIDE_INT rather than an rtx. (clear_mem_offset): New function. * config/mips/mips.c (r10k_safe_mem_expr_p): Take a HOST_WIDE_INT offset rather than an rtx. Assume both the expressio and offset are available. (r10k_needs_protection_p_1): Update accordingly, checking the expression and offset availability here instead. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@176477 138bc75d-0d04-0410-961f-82ee72b054a4
