10201 * calls.c (expand_call): Note calls to malloc, calloc, and realloc;
10202 mark return value from such functions as a pointer and keep track of
10203 them for alias analysis. If a return value from a function is a
10204 pointer, mark it as such.

10206 * cse.c (struct write_data): Delete. No longer needed.
10207 (invalidate): Don't call set_nonvarying_address_components anymore.

10243 (final_giv_value): Likewise.
10244 (find_splittable_regs): Likewise. Only create one new pseudo
10245 if we have multiple address GIVs that were combined with the same
10246 dst_reg GIV. Note when a new register is created due to unrolling.
10247 * rtl.c (reg_note_name): Add REG_NOALIAS.
10248 * rtl.h (enum reg_note): Similarly.

10258 to bootstrap again.
10259 * reload1.c (reload): Sum needs for both OPADDR_ADDR and
10260 OPERAND_ADDRESS when computing how many registers an insn needs.
10261 (reload_reg_free_p): OPADDR_ADDR and OPERAND_ADDRESS reloads do
10263 (reload_reg_free_before_p): Treat OPERAND_ADDRESS reloads just like
10264 OPADDR_ADDR reload.
10265 (reload_reg_reaches_end_p): For RELOAD_FOR_OPADDR_ADDR insns, registers
10266 in reload_reg_use_in_op_addr do not reach the end.
10267 do not reach the end.
