alias.c (static_reg_base_value): New to hold RTL for items allocated once per function for the aliasing code.
* alias.c (static_reg_base_value): New to hold RTL for
items allocated once per function for the aliasing code.
(init_alias_once_per_function): Initialize static_reg_base_value.
(init_alias_analysis): Avoid throw-away allocations of RTL by
using pre-computed values in static_reg_base_value.
* function.c (prepare_function_start): Call
init_alias_once_per_function appropriately.
* rtl.h (init_alias_once_per_function): Declare.
* caller-save (init_caller_save): Restructure slightly to
avoid lots of silly RTL generation.
* expr.c (init_expr_once): Likewise.
* reload1.c (reload_cse_regs_1): Allocate throw-away register
RTL object here. Pass it into children.
(reload_cse_simplify_operands): Use passed-in register RTL
object.
(reload_cse_simplify): Pass through throw-away register
RTL object.
