Subject: 	* config/tc-cris.c (md_estimate_size_before_relax) <case
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=10f455ada0496bfc01006f9191a185b71987a94d;p=pf3gnuchains%2Fpf3gnuchains3x.git

	* config/tc-cris.c (md_estimate_size_before_relax) <case
	ENCODE_RELAX (STATE_CONDITIONAL_BRANCH, STATE_UNDF)>: Don't emit
	32-bit branch, just set fragP->fr_subtype.  Set fragP->fr_var.
	<all cases>: Always set fragP->fr_var using md_cris_relax_table.
	Add cases to cover all relax states.
