re PR target/13186 ([PPC] Internal compiler error in reload.c)
PR target/13186
Revert all of the following patch, except the addition of
hook_bool_machine_mode_true:
2003-11-02 Richard Sandiford <rsandifo@redhat.com>
* Makefile.in (targhooks.o, reload.o): Update dependencies.
(GTFILES): Add targhooks.c.
(gt-targhooks.h): New rule; depend on s-gtype.
* target.h (direct_pool_load_p): New hook.
* target-def.h (TARGET_DIRECT_POOL_LOAD_P): New macro.
(TARGET_INITIALIZER): Include it.
* targhooks.h (default_direct_pool_load_p): Declare.
(hook_bool_machine_mode_true): Declare.
* targhooks.c: Include insn-config.h, recog.h, ggc.h and
gt-targhooks.h.
(pool_symbol): New variable.
(default_direct_pool_load_p): New function.
(hook_bool_machine_mode_true): New function.
* reload.c: Include target.h.
(find_reloads): If an alternative will force a constant into memory,
count an extra reload if constant pool symbols are not valid
addresses. If an alternative uses memory to move values between
registers, count the move as two reloads rather than one.
* config/s390/s390.c (TARGET_DIRECT_POOL_LOAD_P): Define.
* doc/tm.texi (TARGET_DIRECT_POOL_LOAD_P): Document.
