Hello,
A quick note about that 'make.md' document: it's meant as a quick
reference/cheatsheet (hence the _very_ lightweight format) for people
familiar with the make build system. Hadrian's README [1] is a better
place to start from in general and in fact answers or points to
documents that answer some of your questions. I would perhaps recommend
that you (and others) wander through that document and any other doc
that seems relevant to your interests/workflow (e.g testsuite.md,
user-settings.md in your case)
Hadrian is however currently lacking some knobs that are needed to
support some of the things you're asking about. None of this implies a
lot of work and they're all on my TODO. I will certainly make sure to
post an update once this is taken care of, in addition to augmenting the
relevant documents of course. For instance, we don't have a 'validate'
rule at the moment, but we've now got all the pieces we need to write it.
Once I get around to adding those knobs, I'll make sure that all your
questions are answered in the documentation.
Thanks for your initial feedback on this document!

You’ve written a helpful wiki page describing how to use Hadrian
https://gitlab.haskell.org/ghc/ghc/blob/master/hadrian/doc/make.md
Could you document where build-products live? I often look at .hi files.
Could you add
* How to do the equivalent of “sh validate”
* When validating, how to do things like this:
GhcStage1HcOpts += -DDEBUG -O
GhcStage2HcOpts += -Wwarn -ticky
GhcLibHcOpts += -ticky -Wwarn
BUILD_PROF_LIBS = NO
SplitObjs = YES
HADDOCK_DOCS = NO
BUILD_SPHINX_HTML = NO
BUILD_SPHINX_PDF = NO
* After modifying the source code, how to make stage1 compiler
(only). In ‘make’ it is
$ cd compiler; make 1
* After modifying the source code, build the stage2 compiler
(only). In ‘make’ it is
$ cd compiler; make 2
Perhaps you say build –freeze1?
* In the testsuite, how to use the stage1 compiler
$ make stage=1 TEST=T2543
* In nofib, how to build one benchmark, with extra flags, perhaps
even with the stage1 compiler
$ make stage=1 EXTRA_HC_OPTS=”-ticky -ddump-simpl -ddump-stg”
Thanks!
Simon
