cabal new-install doesn't support --ghc-options

[hasufell]

$ cabal new-install --ghc-options='-fllvm -optlo-O2 -j +RTS -A64m -n2m -RTS' all
cabal: unrecognized 'new-install' option `--ghc-options=-fllvm -optlo-O2 -j

[ip1981]

Works with

# cabal --version
cabal-install version 2.2.0.0
compiled using version 2.2.0.1 of the Cabal library

[hasufell]

So it seems this is a regression then

[Mistuke]

Yes I just came here to report this as well. I don't see anything in the changelog so must be a regression.
It's quite a significant one though as it makes reducing GHC problems quite a lot harder.

Any idea what changed here /cc @hvr @23Skidoo ?

[typedrat]

That's very strange, and doesn't seem to be CmdInstall.hs related, since the only change was the addition of new options, not anything that should make old ones go away.

@typedrat another change from 2.2 to 2.4 I see in new-install --help is that the --hadock-* options lost their haddock- prefix; this is quite confusing as this means we get flags such as
