gcc/
* 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.
