Only the Windows compiler notes page mentions -nofloat. None of the others do. So, it needs to be added to these pages: http://dlang.org/dmd-linux.html http://dlang.org/dmd-osx.html http://dlang.org/dmd-freebsd.html
Do we really want to have it there? It's generally not recommended to use it anymore, and I would expect it to be deprecated sooner or later.
Has this gone now?
First PR to fix such inconsistencies: https://github.com/dlang/dmd/pull/7507
The compiler and man pages are now automatically generated from cli.d In the meantime -nofloat has been completely removed. Closing this as FIXED.
