|
|
* Integrate alias analysis changes from jfc@mit.edu
|
|
|
|
* Makefile.in (OBJS): Add alias.o
|
|
|
|
(alias.o): Add dependencies.
|
|
|
|
* alias.c: New file.
|
|
|
|
* sched.c: Remove alias analysis code. It lives in alias.c now.
|
|
|
|
(sched_analyze_2): Add new arguments to true_dependence.
|
|
|
|
(schedule_insns): Always call init_alias_analysis.
|
|
|
|
* 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.

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
|
