Project Member Reported by rahulchaudhry@chromium.org, Apr 26 2017

This issue is the same as the upstream bug https://sourceware.org/bugzilla/show_bug.cgi?id=20364: Data-based padding causes current address evaluation to be non-constant on aarch64.

The bug was introduced on 04-02-2015 in commit https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=c1baaddf8861aea666b84baeb4746caff51a579d: [AArch64] Emit DATA_MAP in order within text section.

It is fixed in upstream binutils master branch, but the fix is not in binutils-2_27-branch.

The fix was made on 08-05-2016 in commit https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=7ea12e5c3ad54da440c08f32da09534e63e515ca: Fix the generation of alignment frags in code sections for AArch64.

Backport for the fix to aosp binutils/binutils-2_27-branch: https://android-review.googlesource.com/#/c/398133
