Hadrian

[Simon Peyton Jones]

Alp
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
