NixOS/nixpkgs#146275 has more discussion on this; the abridged version is that `lld` defaults to using `--build-id=fast` while GNU `ld` defaults to `--build-id=sha1`. These differ in length and so `separate-debug-info.sh`, as of this writing, errors on `lld`'s shorter `--build-id=fast`-generated hashes. `lld` offers the following `build-id` styles: - UUID (random; fast but bad for reproducibility) - fast (xxhash; fast but shorter hashes) - user provided hexstring - SHA1 - MD5 GNU `ld` supports the latter three options, `mold` supports all of these plus SHA256. UUID is out because it's not reproducible, fast isn't supported by GNU `ld` Using a nix provided (sourced from the output base hash) hash as the `build-id` seems tempting but would require a little extra work (we have to include some characteristic of the binary being hashed so that binaries within a derivation still have unique hashes; it seems easy to get this wrong; i.e. a path based approach would make two otherwise identical binaries that reside at different paths have different `build-id` hashes) That leaves SHA1 and MD5 and GNU `ld` already defaults to the former. This commit adds `$NIX_BUILD_ID_STYLE` as an escape hatch, in case any packages have strong opinions about which hash to use. ---- Note that if/when NixOS/nixpkgs#146275 goes through, this change can be reverted if linker speed is a priority. |
