------- Comment #9 from fxcoudert at gcc dot gnu dot org 2006-11-14 10:37 ------- %VAL, %REF and %DESCR have similar use and functionality, but %LOC is very different. It should in fact be an alias for function LOC, but it simply adding it in intrinsic.c with make_alias is not sufficient: creating a symbol name begining with a % has to be added to the parser and the symbol-name-mangler. My (short) attempt to do so failed, but it's probably not very difficult if you understand the binary tree structure of symbol names.
