Hello,
This patch series adds support for CTF generation in GCC.
[Changes from V4]
1. Patch 4 brings in a number of bug fixes and enhancements. Few of them are:
- Use DECL_UID () instead of htab_hash_pointer () for _DECL
- Handle boolean and zero-sized bitfields
- Do not inform () when skipping types. Arguably this was intended for the
GCC developer and not for the end user.
- Other bugfixes around de-dupilication at the time of CTF Array or CTF
function generation.
2. Patch 5 has added testcases.
3. Patch 6 is a new patch added for handling CTF section when LTO is enabled.
Work on CTF spec document is also in progress; will share something very soon.
In the interim, https://sourceware.org/ml/binutils/2019-04/msg00277.html may be
helpful.
For more context, please also see previous posting
https://gcc.gnu.org/ml/gcc-patches/2019-07/msg01209.html
NickA recently posted a changeset to the binutils mailing list that adds initial
support for linking CTF sections. Please see
https://sourceware.org/ml/binutils/2019-09/msg00045.html
( This current GCC patch set has the ctf.h in sync with the above-mentioned
binutils patch set. )
I will be connecting online to talk about the CTF support in GNU toolchain at
Cauldron 2019. Posting these patches so that there is added context.
Testing :
Apart from the usual bootstrap and regression testing on x86_64/linux,
sparc64/linux, I have now compiled more codebases with -gt.
Thanks

Add new function lang_GNU_GIMPLE
Add CTF command line options : -gtLEVEL
