Hi,

This is version 6 of the previously sent RFC series.

Initial (V1) posting contains necessary introductions:
https://sourceware.org/pipermail/binutils/2022-May/120731.html
V2 posting with some improvements:
https://sourceware.org/pipermail/binutils/2022-May/120899.html
V3 posting with further improvements:
https://sourceware.org/pipermail/binutils/2022-June/121245.html
V4 posting with further improvements and bugfixes:
https://sourceware.org/pipermail/binutils/2022-June/121478.html
V5 posting testsuite additions:
https://sourceware.org/pipermail/binutils/2022-July/121839.html

The commit log of each patch in the current patch series specifies the changes
from the version V5 of the respective patch.  Briefly, this patch series has
improved testsuites/infrastructure.

1. libctfframe/testsuite now uses recursive makefiles for building test programs.
2. Unwinder tests are still present in libctfframe/testsuite/libctfframe.unwind.
The code for the unwinding library for backtracing using CTF Frame (a.k.a.
libctfbacktrace) still sits in the libctfframe/ folder.

Testing notes:
- Tested natively on x86_64-linux, aarch64-linux
- Cross builds for various targets on x86_64 host.  Ran a regression script
that checks for failures in gas, ld, binutils, libctf with no reported
regressions. libctfframe tests ran as expected. libctfbacktrace/unwinder
tests (which are present in libctfframe/testsuite/libctfframe.unwind) have been
disabled when host != target.

Important note: libctfframe/configure has NOT been included in the patch
series, as it causes the size of some patches to go beyond the allowed limit.
Please regenerate the libctfframe/configure after applying the series.

Thanks,

Indu Bhagat (7):
