Re: Productivity Tip from mpickering

(Not really) funny observation, that page and hadrian/doc/README.md have about the same, but slightly different information. I don't know which one to believe! - Oleg On 26.5.2021 15.38, Richard Eisenberg wrote:

Could you add this insight to the wiki somewhere, so we can find it later? https://gitlab.haskell.org/ghc/ghc/-/wikis/building/hadrian seems like the right place.

Thanks! Richard

Hi,

I am now using a new flavour combination which is proving *very* nice as a compromise between fast recompiles and passing tests.

My normal build command is now:

./hadrian/build --flavour=default+no_profiled_libs+omit_pragmas --freeze1 -j

This has the effect of

* base libraries are compiled with optimisation * Profiling libraries are not built * Stage 1 compiler is compiled with -O + -fomit-interface-pragmas, so recompilation behaviour is much better.

The end result is a nearly clean testsuite run (I think there are two failures) but much faster iterations when modifying `compiler/*`.

Cheers,
