From 9a2284679086e32c0c2a46e08b23edde6fc8be85 Mon Sep 17 00:00:00 2001 From: Jiong Wang Date: Mon, 22 Feb 2016 12:16:06 +0000 Subject: [PATCH] [AArch64] Remove redundant calculation of plt stub destination for veneer elfNN_aarch64_size_stubs, the caller of aarch64_type_stub has redirected the final destination of long branch veneer to plt stub if the call should go through it. It's redundant to do the same check and redirect again from scratch inside aarch64_type_stub. bfd/ * elfnn-aarch64. (aarch64_type_of_stub): Remove redundation calcuation for destination. Remove useless function parameters. (elfNN_aarch64_size_stubs): Update parameters for aarch64_type_of_stub. --- bfd/ChangeLog | 6 ++++++ bfd/elfnn-aarch64.c | 19 +++---------------- 2 files changed, 9 insertions(+), 16 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 17b24c10b0..7878822208 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,9 @@ +2016-02-22 Jiong Wang + + * elfnn-aarch64.
