  This patch mostly removes priority coloring (I don't think it is
worth to be used), makes the mixed algorithm by default (instead of the
regional one).

2007-12-17  Vladimir Makarov  <vmakarov@redhat.com>

	* doc/invoke.texi (fira-algoirthm): Remove prioirity coloring.
	Make mixed the default.

	* flags.h (ira_algorithm): Remove IRA_ALGORITHM_PRIORITY.

	* ira-color.c (priority_coloring):  Remove.
	(do_coloring): Don't call priority_coloring.

	* opts.c (common_handle_option): Remove priority coloring option.

	* toplev.c (flag_ira_algorithm): Assign IRA_ALGORITHM_MIXED.
	* ira-build.c (check_and_add_conflicts, ira_flattening): Increase
	threshold for internal_flag_ira_verbose.
