This has never been worked on and hence archived. The idea is not ditched, so I'm planning to resume it once I have time.
official LLVM BOLT tutorial implemented in nix.
Seen as the base for optimizing compiler infrastructure easily available out-of-the box.
basically not yet implemented
This is experimental project for the author to hack around in his spare time and comes without any guarantees of project's reaching the state of minimum usability and / or feature completness.
No assumptions currently should be made about contents / availability of this repo. Everything here is a subject to changes or permanent deletion, including this disclaimer, as well as the repo itself might become temporarily or permanently unavailale.
As basically every modern compiler is optimizing, to avoid ambiguity, the scope of this project is well defined and is all about ensuring BOLT support, both:
- for bootstrapping compilers themselves and thus speeding up compilation
- ensuring BOLT is supported by compilers to build other software
With lesser priority, PGO and LTO are also in the scope and will be enabled by default, if that doesn't occur to slow down the development (read "just works", givent the current author's setup).

- make it work to any extent

rustcsupport -
go 1.18+support - creation of a collection of
nix-shellbuild environments which use optimizing compilers - overriding / overlaying the
nixpkgspackages which would greately benefit from being built by optimizing compiler [and are not configured this way by default] e.g.: nixpkgs versions of Python
