+ * combine.c, df-problems.c, df-scan.c, emit-rtl.c, reginfo.c,
+ reload.c, rtlanal.c: Remove comparison of ARG_FRAME_POINTER_REGNUM
+ and FRAME_POINTER_REGNUM with the preprocessor.
+
+2015-05-20 Trevor Saunders <tbsaunde+gcc@tbsaunde.org>
+
* defaults.h: Add default for STACK_PUSH_CODE.
* expr.c: Don't redefine STACK_PUSH_CODE.
* recog.c: Likewise.
