# ToDo List.
#
#   * finish installation
#     * Windows: should we have ghc-pkg-<version>?
#     * should we be stripping things?
#     * install libgmp.a, gmp.h
#   * need to fix Cabal for new Windows layout, see
#     Distribution/Simple/GHC.configureToolchain.
#   * remove old Makefiles, add new stubs for building in subdirs

#   * optionally install stage3?
#   * add Makefiles for the rest of the utils/ programs that aren't built
#     by default (need to exclude them from 'make all' too)
#
# Tickets we can now close, or fix and close:
#
#   * 1693 make distclean

# Possible cleanups:
#
#   * per-source-file dependencies instead of one .depend file?
#   * eliminate undefined variables, and use --warn-undefined-variables?
#   * put outputs from different ways in different subdirs of distdir/build,
#     then we don't have to use -osuf/-hisuf.  We would have to install
#     them in different places too, so we'd need ghc-pkg support for packages
#     of different ways.
#   * make PACKAGES generated by configure or sh boot?
#   * we should use a directory of package.conf files rather than a single
#     file for the inplace package database, so that we can express
#     dependencies more accurately.  Otherwise it's possible to get into
#     a state where the package database is out of date, and the build
#     system doesn't know.

# Setting foo_dist_DISABLE=YES means "in directory foo, for build
# "dist", just read the package-data.mk file, do not build anything".

# We carefully engineer things so that we can build the
# package-data.mk files early on: they depend only on a few tools also
# built early.  Having got the package-data.mk files built, we can
# restart make with up-to-date information about all the packages
# (this is phase 0).  The remaining problem is the .depend files:
#
#   - .depend files in libraries need the stage 1 compiler to build
#   - ghc/stage1/.depend needs compiler/stage1 built
#   - compiler/stage1/.depend needs the bootstrap libs built
#
# GHC 6.11+ can build a .depend file without having built the
# dependencies of the package, but we can't rely on the bootstrapping
# compiler being able to do this, which is why we have to separate the
# three phases above.

# So this is the final ordering:

# Phase 0 : all package-data.mk files
#           (requires ghc-cabal, ghc-pkg, mkdirhier, dummy-ghc etc.)
# Phase 1 : .depend files for bootstrap libs
#           (requires hsc2hs)
# Phase 2 : compiler/stage1/.depend
#           (requires bootstrap libs and genprimopcode)
# Phase 3 : ghc/stage1/.depend
#           (requires compiler/stage1)
#
# The rest : libraries/*/dist-install, compiler/stage2, ghc/stage2
