Subject: Fix documentation of the new parameters.
X-Git-Url: http://git.sourceforge.jp/view?p=pf3gnuchains%2Fgcc-fork.git;a=commitdiff_plain;h=4a1b38089c1a681c30a6e9728f4354b53a3921b6

Fix documentation of the new parameters.

2010-03-10  Sebastian Pop  <sebastian.pop@amd.com>

	* doc/invoke.texi: Fix documentation of graphite-max-nb-scop-params,
	graphite-max-bbs-per-function, and loop-block-tile-size.
	* params.def (PARAM_GRAPHITE_MAX_NB_SCOP_PARAMS): Replace "maximal"
	with "maximum".
	(PARAM_GRAPHITE_MAX_BBS_PER_FUNCTION): Same.
