Subject: Add operator* to gimple_stmt_iterator and gphi_iterator
X-Git-Tag: basepoints/gcc-15~9996
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c39cdd9e654540f74cd2478019c40f1611554a44;p=thirdparty%2Fgcc.git

Add operator* to gimple_stmt_iterator and gphi_iterator

This allows STL style iterator dereference.  It's the same
as gsi_stmt () or .phi ().

	* gimple-iterator.h (gimple_stmt_iterator::operator*): Add.
	(gphi_iterator::operator*): Likewise.
