From 279b2f94168ee91e02ccd070d27c983fc001fe12 Mon Sep 17 00:00:00 2001
From: Renlin Li <renlin.li@arm.com>
Date: Sat, 3 Feb 2018 13:18:17 +0000
Subject: [PATCH] [PR22764][LD][AARCH64]Allow R_AARCH64_ABS16 and
R_AARCH64_ABS32 against absolution symbol or undefine symbol in shared
object.
The assumption that R_AARCH64_ABS16 and R_AARCH64_ABS32 relocation in LP64 abi
will be used to generate an address does not hold for absolute symbol.
In this case, it is a value fixed at static linking time.
The condition to check the relocations is relax to allow absolute symbol and
undefined symbol case.

R_AARCH64_ABS32 and R_AARCH64_ABS16 for absolute symbol. Apply the

+* Add --generate-missing-build-notes=[yes|no] option to create (or not) GNU
+ Build Attribute notes if none are present in the input sources. Add a

Changes in 2.30:
* Add support for loaction views in DWARF debug line information.
