Subject: libobjc, Darwin : Fix powerpc encoding regression.
X-Git-Tag: releases/gcc-10.3.0~489
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e731714eb2b4844771fa6f2a7a80d863490b8e6d;p=thirdparty%2Fgcc.git

libobjc, Darwin : Fix powerpc encoding regression.

This corrects a typo in the recipe for the special type alignment
rules that are used for 32bit powerpc Darwin platforms.

libobjc/ChangeLog:

	* encoding.c (_darwin_rs6000_special_round_type_align):
	Use DFMode in the emulation of the special round type.

(cherry picked from commit dcd9800fcd42489034c0774247eb898d79b1ea2d)
