From 8a89dbd24275d78205f408da9acdee092850dc5a Mon Sep 17 00:00:00 2001 From: Richard Sandiford Date: Thu, 4 Dec 2003 09:11:19 +0000 Subject: 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 * 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.
