Subject: [PATCH] params.def (PARAM_MAX_SCHED_EXTEND_REGIONS_ITERS): Change
default value to 0.
2006-06-06 Maxim Kuvyrkov <mkuvyrkov@ispras.ru>

value to 0.
* doc/invoke.texi (max-sched-extend-regions-iters): Document.
* config/ia64/ia64.c (params.h): New header.
(ia64_optimization_options): New function to adjust parameters.
* config/ia64/ia64-protos.h (ia64_optimization_options): New prototype.
* config/ia64/ia64.h (OPTIMIZATION_OPTIONS): New macro.
* config/ia64/t-ia64 (ia64.o): Add dependence from params.h .
