From 1521477a53ec805e4106eb34cc7c33e29f5d1efb Mon Sep 17 00:00:00 2001 From: Doug Kwan Date: Fri, 29 Jan 2010 22:16:17 +0000 Subject: [PATCH] 2010-01-29 Doug Kwan * arm.cc (Arm_relocate_functions::arm_branch_common) Change visibility to public. (Arm_relocate_functions::thumb_branch_common): Ditto. (Arm_relocate_functions::thm_call, Arm_relocate_functions::thm_jump24, Arm_relocate_functions::thm_xpc22, Arm_relocate_functions::plt32, Arm_relocate_functions::xpc25, Arm_relocate_functions::call, Arm_relocate_functions::jump24): Remove. (Target_arm::Relocate::relocate): Adjust code to call Arm_relocation_functions::arm_branch_common and Arm_relocation_functions::thumb_branch_common instead of their removed wrappers. Merge switch-cases together to reduce source code size. --- gold/ChangeLog | 14 +++++ gold/arm.cc | 160 +++++---------------------------------------------------- 2 files changed, 26 insertions(+), 148 deletions(-) diff --git a/gold/ChangeLog b/gold/ChangeLog index 65c30b7..98b7dec 100644 --- a/gold/ChangeLog +++ b/gold/ChangeLog @@ -1,5 +1,19 @@ 2010-01-29 Doug Kwan + * arm.cc (Arm_relocate_functions::arm_branch_common) Change visibility + to public. + (Arm_relocate_functions::thumb_branch_common): Ditto. + (Arm_relocate_functions::thm_call, Arm_relocate_functions::thm_jump24, + Arm_relocate_functions::thm_xpc22, Arm_relocate_functions::plt32, + Arm_relocate_functions::xpc25, Arm_relocate_functions::call, + Arm_relocate_functions::jump24): Remove. + (Target_arm::Relocate::relocate): Adjust code to call + Arm_relocation_functions::arm_branch_common and + Arm_relocation_functions::thumb_branch_common instead of their removed + wrappers.
