This is memory aliasing info. The a+0 is the variable+offset. The A32 is the alignment, 32-bits. The S4 is the size, 4-bytes. The "0" is the alias set. Objects are grouped into sets, where each item in the set may alias any other item in the set. Since you have only one item, it is in set 0. In the gcc sources, see the MEM_ALIAS_SET, MEM_EXPR, MEM_OFFSET, MEM_SIZE, and MEM_ALIGN attributes for mem rtx. This kind of question should probably go to the gcc@xxxxxxxxxxx list instead of a linux kernel list. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
