+ * function.c (locate_and_pad_parm): Don't align stack unconditionally.
+ Fixes execute/20001017-1.c on pwerpc-linux-gnu.
+
+ * expr.c (store_constructor): Apply MEM_ALIAS_SET to MEMs only.
+ * rs6000/rs6000.c (rs6000_hash_constant): use X0INT to access a
+ LABEL_REF.
+
+ * rs6000/rs6000.h (NO_DOLLAR_IN_LABEL, DOLLARS_IN_IDENTIFIERS,
+ ENCODE_SECTION_INFO, ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): Move from
+ here...
+ * rs6000/aix.h: ...to here.
+ * rs6000/linux.h (ASM_APP_ON, ASM_APP_OFF): Define to Linux-style.
