 asa | oh I see | 22:28:03 |
| asa | sorry for the misunderstanding, I'm not sure where I read the thin lto by default thing | 22:28:31 |
| asa | the profiles page you linked to does say that lto=false is different from lto=off though, and that lto=false enables "thin local lto" | 22:29:54 |
 K900 | That should be our default as well, as I don't think we explicitly pass lto=false? | 22:39:17 |
 whispers (it/fae) | i think we just inherit whatever upstream has profile.release set to? | 22:42:20 |
| asa | probably is? idk how rustc deals with default options | 22:42:21 |

| asa | In reply to @k900:0upti.me
And even -C opt-level=3 is different from -O3 never thought about this but I guess it's a good thing rust release builds don't use fast-math by default... | 22:44:11 |
| asa | i looked into this more and it seems thin local lto is redundant with codegen-units=1 anyway (and rustc disables thin local lto if codegen-units=1 and the lto level is unspecified)
buildRustCrate has defaultCodegenUnits ? 1 since the derivation doesn't allow for rebuilds on a higher granularity than per-crate anyway
