Subject: bitmap: Fix comment about tree representation
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bee542c6b13fb08607dc03aadf5cd5eef5fe6642;p=thirdparty%2Fgcc.git

bitmap: Fix comment about tree representation

The bitmap_element comments appear to have the left and right children
the wrong way around: prev is the left (lower index) and next is the
right (higher index).

gcc/
	* bitmap.h (bitmap_element): Fix left/right distinction in comments.
