* calls.c (expand_call): Note calls to malloc, calloc, and realloc;
|
|
mark return value from such functions as a pointer and keep track of
|
|
them for alias analysis. If a return value from a function is a
|
|
pointer, mark it as such.
|
|
* combine.c (distribute_notes): Handle REG_NOALIAS.
|
|
* cse.c (struct write_data): Delete. No longer needed.
|
|
(invalidate): Don't call set_nonvarying_address_components anymore.
|
|
Use true_dependence to decide if an entry should be removed from
|
|
the hash table.
|
|
(invalidate_memory): Remove WRITES argument, simplify appropriately.
|
|
Fix all callers.
|
|
(note_mem_written): Similarly for WRITE_PTR argument.

(refers_to_mem_p, cse_rtx_addr_varies_p): Deleted.
|
|
(cse_rtx_varies_p): New function. Derived from old
|
|
cse_rtx_addr_varies_p.
|
|
(cse_insn): Remove WRITES_MEMORY and INIT variables and all references.
|
|
Don't call note_mem_written anymore. Stack pushes invalidate the stack
|
|
pointer if PUSH_ROUNDING is defined. No longer need to call
|
|
cse_rtx_addr_varies_p to decide if a MEM should be invalidated.
|
|
(skipped_writes_memory): Remove variable.
|
|
(invalidate_skipped_set): Simplify and wewrite to use invalidate_memory.
|
|
(invalidate_skipped_block): Simplify for new alias analysis code.
|
|
(cse_set_around_loop): Likewise.
|
|
(cse_main): Call init_alias_analysis.
|
|
* flags.h (flag_alias_check, flag_argument_noalias): Declare.
|
|
* toplev.c (flag_alias_check, flag_argument_noalias): Define.
|
|
(f_options): Add new alias checking arguments.
|
|
(main): Set flag_alias_check when optimizing.
|
|
* local_alloc (validate_equiv_mem_from_store): Add new arguments
|
|
to true_dependence.
|
|
(memref_referenced_p): Likewise.
|
|
* loop.c (NUM_STORES): Increase to 30.
|
|
(prescan_loop): Only non-constant calls set unknown_address_altered.
|
|
(invariant_p): Add new arguments to true_dependence.
|
|
(record_giv): Initialize unrolled and shared fields.
|
|
(emit_iv_add_mult): Call record_base_value as needed.
|
|
* loop.h (struct induction): Add unrolled and shared fields.
|
|
* unroll.c (unroll_loop): Call record_base_value as needed.
|
|
(copy_loop_body): Likewise.
|
|
(final_biv_value): Likewise.
|
|
(final_giv_value): Likewise.
|
|
(find_splittable_regs): Likewise. Only create one new pseudo
|
|
if we have multiple address GIVs that were combined with the same
|
|
dst_reg GIV. Note when a new register is created due to unrolling.
|
|
* rtl.c (reg_note_name): Add REG_NOALIAS.
|
|
* rtl.h (enum reg_note): Similarly.
|
|
(rtx_varies_p, may_trap_p, side_effects_p): Declare.
|
|
(volatile_refs_p, volatile_insn_p, remove_note): Likewise.
|

(note_stores, refers_to_regno_p, reg_overlap_mentioned_p): Likewise.
|
|
(true_dependence, read_dependence, anti_dependence): Likewise.
|
|
(output_dependence, init_alias_analysis, end_alias_analysis): Likewise.
|
|
(mark_user_reg, mark_reg_pointer): Likewise.
|
|
|
|
|
|
* Integrate reload bugfix from Wilon which enables the PA port
|
|
to bootstrap again.
|
|
* reload1.c (reload): Sum needs for both OPADDR_ADDR and and
|
|
OPERAND_ADDRESS when computing how many registers an insn needs.
|
|
(reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
|
|
conflict.
|
|
(reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
|
|
OPADDR_ADDR reload.
|
|
(reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
|
|
in reload_reg_use_in_op_addr do not reach the end.
|
|
do not reach the end.
|
|
(reloads_conflict): RELOAD_FOR_OPADDR_ADDR conflicts with
|
|
RELOAD_FOR_OPERAND_ADDRESS.
