This is a good set of changes from the looks of it, I'll give this a look over when I have the time. Right now, my priority is on making all LLVM subpackages common and I am hoping to get that done asap so this PR will probably take a bit for me to look over. I also don't want to have to rebase that PR heh. |

There was a problem hiding this comment.
Shouldn't this be unconditional, so that Linux users catch it if the replacement starts failing?

Sure, I can make it unconditional.

It’s unconditional now. I also moved it to postPatch. Clang 16 already correctly had it there. Now they all should.

Rebased and dropped clang 9 since it was removed in #302750. |

This pull request has been mentioned on NixOS Discourse. There might be relevant details there: |
fixes NixOS#302629 After updating from `3.15.0 -> 3.19.2` build for `goose` was failing. This was due to the tests failing esp on integration tests which required the docker darmon to be running. Tests with similar nature were already skipped, but on the upgraded version newer integration tests were added. This change adds these changes to the test skip list aswell. Skip following tests which require a docker daemon to be running - TestLockModeAdvisorySession - TestDialectStore - TestGoMigrationStats - TestPostgresSessionLocker Links: - Commit adding the new integration tests: pressly/goose@b2c483a
qt: convert warnings to throw
Firefox: 124.0.2 -> 125.0; 115.9.0esr -> 115.10.0esr
goose: update test skip list with newer tests
Clang assumes that `libLTO.dylib` is located at `../lib` in the same prefix as `clang`, but that’s not true in nixpkgs. `libLTO.dylib` is actually located at `libllvm^lib/lib.libLTO.dylib`.

Closing because of the mass ping. I’ll reopen targeting staging with the consolidated clang. |

Description of changes
Clang assumes that
libLTO.dylibis located at../libin the same prefix asclang, but that’s not true in nixpkgs.libLTO.dylibis actually located atlibllvm^lib/lib.libLTO.dylib.This is the first piece to fixing LTO on Darwin. The other is updating ld64, which I will be doing in a separate PR later this week. This PR does not depend on that PR because there is no harm passing the correct path to ld64. It does not perform LTO by default, and trying to use
-fltoeven with the correct path remains broken.Testing was done using my WIP PR for ld64 with clang 16. See #19098 (comment) for output. It can also be validated by setting
NIX_DEBUG=1when running clang, then confirming that the path passed to-lto_libraryactually exists in the store.Things done
