Summary
Adds
-fno-math-errnoto UnixCMAKE_*_FLAGS_RELEASEalongside the existing-ffast-math. This is a standard pairing: it avoids errno writes from inlinedlibmcalls in hot paths, improving codegen and slightly reducing overhead, while remaining consistent with the project’s existing fast-math choice for Release.Debug / ASan paths are unchanged.
Note on “everything on main”
Open PR #2 (
cursor/sturmgeist-main-ci-sync-bee0) is merge-conflicting with currentmainand would revert large parts of the fork (CI fixes, vendored JoyStick, docs). It should be closed or fully rebased before merge—not applied as-is.Testing
