gcc : ChangeLog.RA ra.c
Log message:
2002-01-19 Michael Matz <matzmich@cs.tu-berlin.de>
* ra.c (ok): Wide webs coalesced to precolored ones take more
than one hardweb. Check all of them for non-conflict.
(colorize_one_web): Even when using usable_regs try first
the preferred colors of them.
(try_recolor_web): Check mode and wide coalesced precolored webs.
(regnos_coalesced_to_hardregs): New.
(emit_colors): Initialize it.
(init_ra): Don't skip some regs when looking for all regs for a mode.
(remove_suspicious_death_notes): New.
(reg_alloc): Call it.
