From 6244b14e3997fcae97a44b3287eac59a42b0c2f1 Mon Sep 17 00:00:00 2001 From: Eric Botcazou Date: Sun, 4 Jul 2004 23:42:28 +0200 Subject: [PATCH] sparc.c (SIBCALL_SLOT_EMPTY_P): Rename into LEAF_SIBCALL_SLOT_RESERVED_P after negation. * config/sparc/sparc.c (SIBCALL_SLOT_EMPTY_P): Rename into LEAF_SIBCALL_SLOT_RESERVED_P after negation. (eligible_for_sibcall_delay): Adjust use of SIBCALL_SLOT_EMPTY_P. (output_restore): Change parameter from 'insn' to 'pat'. (output_return): Adjust call to output_restore. (output_sibcall): Adjust use of SIBCALL_SLOT_EMPTY_P. Adjust call to output_restore.
