* resource.h (enum mark_resource_type): Remove member MARK_DEST. The only user changed as follows: * resource.c (mark_set_resources) <case SET>: Always recurse for SET_SRC (x). <case SIGN_EXTRACT, case ZERO_EXTRACT>: Always recurse on operands. <case STRICT_LOW_PART>: Delete, deferring to default code. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@74328 138bc75d-0d04-0410-961f-82ee72b054a4
