Might you add info on what “validate” understands to https://ghc.haskell.org/trac/ghc/wiki/TestingPatches? Done. There is also `./validate --help`. And ditto the V flags to https://ghc.haskell.org/trac/ghc/wiki/Building/Hacking Ok, but I put it on this page instead: https://ghc.haskell.org/trac/ghc/wiki/Building/Using#Buildconfiguration https://ghc.haskell.org/trac/ghc/wiki/Building/Using#Verbosebuild The `V=0` option is also discoverable from the `mk/build.mk.sample` file.
