If things go well, I'll try to jump to 8.10 (build 8.8 without
committing, build new bootstrappers from that, and then work on
8.10).
While here, make it possible to build the bootstrappers with
PORTS_PRIVSEP enabled (dirty and brittle, but works for me[tm]).
ghc and the hs-packages now simply include the necessary (haskell)
package description files in lib/ghc/package.conf.d and update the
package.cache by running ghc-pkg recache at the end. register and
unregister scripts are no longer needed.
To my surprise, it just works, and there are no hs library signature
changes, so there's no need to touch all the hs-* ports.
Next steps will be (in no particular order): enable PIE, update to
ghc 8.4, kill W^X, debug and fix the SIG(SEGV|TRAP|BUS|ILL) problems
with tehmplate haskell seen by some people.
are available fails badly if the ghc-prim package contains more
than one entry in the library-dirs: field, which is currently the
case for our ghc port.
Only check for the existance of vertain files in the first entry
of the library-dirs: field to re-enable tons of previously disabled
tests and to get rid of stupid "/bin/sh: [: ... unexpected
operator/operand" errors.
This should be fixed for real at both our side (don't include the
same directory twice in the library-dirs: field) and upstream (don't
rely on the library-dirs: field only containing one directory).
or ghc-8.2.x (yet untested).
Also, don't build iserv with -threading if multithreading is disabled
(which is the case for the bootstrappers we build). I could also have
patched out iserv from the bindist targets, but this way it's simpler.
ghc uses cc for generating object files from assembler files and
passes the CONF_CC_OPTS_STAGE? flags to it, which clang doesn't
like, so add -Wno-unused-command-line-argument to the flags passed
to cc if it's clang.
To let this work for the bootstrap compiler, properly CONFIGURE_ENV
when installing the bootstrap (in post-patch:). This also makes the
hack patching the bootstrap/bin/ghc script in post-patch: obsolete.

~here are still a lot of warnings, most about macros #defined in
storage/ClosureMacros.h. Those should be fixed in a separate step,
probably after an update to ghc-8.
as the patch shows).
you'll need to wait for a bootstrap/rebootrap yourself so this is actually
effective.
(should cut down *a lot* on the insane number of warnings produced due to
unknown compile options on a clang system)
okay kili@
the linker again. Otherwise, the ld wrapper script installed when
USE_WXNEEDED=Yes will be used by the installed ghc package.
Problem noticed by Karel Gardas.
A real fix would be to remove PROT_EXEC from mmapForLinker() in
rts/Linker.c and to flip PROT_WRITE / PROT_EXEC in loadObj_()
when it's done, but this requires a little bit more time for
testing (turnaround times for building and testing ghc aren't
that funny).
following the recent change to pledge(2) (passing NULL doesn't change
the value).
- Use maybeWith instead of pattern matching to distinguish between
Nothing and Just x.
- Add some minimal documentation.
only one function giving access to the pledge(2) system call:
pledge :: String -> Maybe [FilePath] -> IO ()
Help and testing by semarie@ and abieber@. Thanks!
No bump yet, because there'll be some more churn (so please wait a
little bit for other haskell commits before starting to build it).
