Subject: tree: Remove KFmode workaround [PR112993]
X-Git-Tag: basepoints/gcc-16~7466
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b5c813ed6035cf6ef831927e66e184a5847afbe6;p=thirdparty%2Fgcc.git

tree: Remove KFmode workaround [PR112993]

The fix for PR112993 makes KFmode have 128 bit mode precision,
we don't need this workaround to fix up the type precision any
more, and just go with mode precision.  So this patch is to
remove KFmode workaround.

	PR target/112993

gcc/ChangeLog:

	* tree.cc (build_common_tree_nodes): Drop the workaround for rs6000
	KFmode precision adjustment.
