From a35ad1689150363a44dc08da824b57a6de14e957 Mon Sep 17 00:00:00 2001 From: Doug Evans Date: Fri, 24 Sep 1993 19:56:05 +0000 Subject: [PATCH] stmt.c: (expand_goto): Set hard_frame_pointer_rtx when restoring the frame. * stmt.c: (expand_goto): Set hard_frame_pointer_rtx when restoring the frame. Use it when restoring other registers. (expand_end_bindings): ARG_POINTER_REGNUM will be eliminated into HARD_FRAME_POINTER_REGNUM, not FRAME_POINTER_REGNUM; adjust code accordingly.
