Linaro GDB

Investigate backporting aarch64 support

Registered by Michael Hope

ARM have submitted support for aarch64 to GDB trunk. This should be accepted and released as part of GDB 7.6 in six months time.

It would be nice to have a stable backport in the interim. Investigate backporting support to Linaro GDB 7.5, the cost of keeping the backport up to date, and recommend what we should do.

Whiteboard

[1] we don't want the aarch64 backport affecting existing ARM or x86 support.

2012-11-07 michaelh1 blocked on ptrace support in upstream GDB and kernel
2013-01-10 matthew-gretton-dann blocked on non-acceptance upstream (still) and 7.6 being close - meaning we'll do the backport to gain no time.

[2013-08-22 matthew-gretton-dann] 7.6 was released with GDB support for AArch64 nothing needed on backport.
