WIP: GCC with separated runtime libraries #132343
Conversation
Taking a bunch of stuff from 11 packages
* `builtins.attrNames gccNgPackages_11` now evaluates * Added missing inputs * Removed a bunch of clang-related things - clang-only packages: compiler-rt, libcxx, libcxxabi, openmp - useLLVM logic - stdenvs / cc-wrappers which are not applicable anymore * Removed LLVM-specific relics like the default callPackage bindings, clean up default callPackage scopes for libraries and tools * Add runtime libraries (may forgot some) to libraries set

Oh no, I forgot to push my stuff! I'll merge. Actually comments won't be too bad. |
Create patch so that thread model can be specified explicitly rather than being inferred from GCC.
There is a still a build failure, but I am going to just use Musl and ignore this for now.
Unfortunately, libstdcxx doesn't link, evidentally because inconsistent `-fPIC`.

Hi, It is a bummer that this sort of fell by the wayside. I just wanted to mention that enabling the goals of this PR is one of the major benefits sought by #209870. Specifically, if that PR merges, my next project will be to start moving the libraries that are bundled with gcc into separate packages -- like this PR, but one at a time, and incrementally rather than in a big rewrite. I would like to reuse as much of the work here as possible. |

@amjoseph-nixpkgs #132343 (comment) it is a bummer, and I would love to pair with you on this to get it over the hill at some point. there was just some things I was banging my head against the wall debugging that I need another pair of eyes on. |
