2438 | * calls.c (expand_call): Note calls to malloc, calloc, and realloc; | |
2439 | mark return value from such functions as a pointer and keep track of | |
2440 | them for alias analysis. If a return value from a function is a | |
2441 | pointer, mark it as such. | |

2443 | * cse.c (struct write_data): Delete. No longer needed. | |
2444 | (invalidate): Don't call set_nonvarying_address_components anymore. | |
2445 | Use true_dependence to decide if an entry should be removed from | |
2446 | the hash table. | |
2447 | (invalidate_memory): Remove WRITES argument, simplify appropriately. | |
2448 | Fix all callers. | |
2449 | (note_mem_written): Similarly for WRITE_PTR argument. | |

2454 | cse_rtx_addr_varies_p. | |
2455 | (cse_insn): Remove WRITES_MEMORY and INIT variables and all references. | |
2456 | Don't call note_mem_written anymore. Stack pushes invalidate the stack | |
2457 | pointer if PUSH_ROUNDING is defined. No longer need to call | |
2458 | cse_rtx_addr_varies_p to decide if a MEM should be invalidated. | |
2459 | (skipped_writes_memory): Remove variable. | |
2460 | (invalidate_skipped_set): Simplify and wewrite to use invalidate_memory. | |

2480 | (final_giv_value): Likewise. | |
2481 | (find_splittable_regs): Likewise. Only create one new pseudo | |
2482 | if we have multiple address GIVs that were combined with the same | |
2483 | dst_reg GIV. Note when a new register is created due to unrolling. | |

2494 | * Integrate reload bugfix from Wilon which enables the PA port | |
5fa39bfe JL |
2495 | to bootstrap again. |
2496 | * reload1.c (reload): Sum needs for both OPADDR_ADDR and and | |
2497 | OPERAND_ADDRESS when computing how many registers an insn needs. | |
2498 | (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do | |
2499 | conflict. | |
2500 | (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like | |
