* haifa-sched.c: Convert to target hooks. Macros replaced
are ISSUE_RATE, ADJUST_COST, ADJUST_PRIORITY, MD_SCHED_INIT,
MD_SCHED_REORDER, MD_SCHED_REORDER2, MD_SCHED_VARIABLE_ISSUE,
MD_SCHED_FINISH, and HAVE_cycle_display.
* target-def.h (TARGET_SCHED_ADJUST_COST,
TARGET_SCHED_ADJUST_PRIORITY, TARGET_SCHED_ISSUE_RATE,
TARGET_SCHED_VARIABLE_ISSUE, TARGET_SCHED_INIT,
TARGET_SCHED_FINISH, TARGET_SCHED_REORDER,
TARGET_SCHED_REORDER2, TARGET_SCHED_CYCLE_DISPLAY):
New hook #defines to be overridden.
(TARGET_SCHED): Bring them all together.
(TARGET_INITIALIZER): Update.
* target.h: Don't forward declare struct rtx_def. Use 'rtx'
instead of 'struct rtx_def *' throughout.
(struct sched): New set of hooks for the scheduler.
* Makefile.in (haifa-sched.o): Depend on target.h.
* doc/tm.texi: Document the new scheduler hooks, together in
their own section, instead of scattered around.
Fix a bunch of underfull/overfull hboxes.
* a29k.h, alpha.h, arm.h, c4x.h, convex.h, d30v.h, i386.h,
ia64.h, m32r.h, m88k.h, mips.h, pa.h, rs6000.h, s390.h, sh.h,
sparc.h: Don't define any of the old scheduler macros.
* a29k.c, alpha.c, arm.c, c4x.c, convex.c, d30v.c, i386.c,
ia64.c, m32r.c, m88k.c, mips.c, pa.c, rs6000.c, s390.c, sh.c,
sparc.c: Create hook functions from code extracted from
corresponding target header, or make existing hooks static, as
appropriate. Set the appropriate entries in targetm.
* alpha-protos.h, arm-protos.h, c4x-protos.h, d30v-protos.h,
i386-protos.h, ia64-protos.h, m32r-protos.h, pa-protos.h,
rs6000-protos.h, s390-protos.h, sparc-protos.h:
Remove prototypes for functions which are now static.
* d30v.h, d30v.c, m32r.h, m32r.c: Remove #ifdef HAIFA and
related gunk; the Haifa scheduler is now the only choice.
