<p>(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!<br>

Could you add this insight to the wiki somewhere, so we can find
it later? <a

class="" moz-do-not-send="true">https://gitlab.haskell.org/ghc/ghc/-/wikis/building/hadrian</a> seems
like the right place.

<div class="">Hi,<br class="">
<br class="">
I am now using a new flavour combination which is
proving *very* nice<br class="">
as a compromise between fast recompiles and passing
tests.<br class="">
<br class="">
My normal build command is now:<br class="">
<br class="">
./hadrian/build
--flavour=default+no_profiled_libs+omit_pragmas
--freeze1 -j<br class="">
<br class="">
This has the effect of<br class="">
<br class="">
* base libraries are compiled with optimisation<br
class="">
* Profiling libraries are not built<br class="">
* Stage 1 compiler is compiled with -O +
-fomit-interface-pragmas, so<br class="">
recompilation behaviour is much better.<br class="">
<br class="">
The end result is a nearly clean testsuite run (I think
there are two<br class="">
failures) but much faster iterations when modifying
`compiler/*`.<br class="">
<br class="">
Cheers,<br class="">
<br class="">
Matt<br class="">
