Somehow I forgot to totally remove `gmpContext` in
d7029cc09edc052c2f97effe33233c53340fcce0. This patch fixes it and adds
some additional comments.

* Hadrian doesn't use integer-gmp/config.mk file anymore to determine if
building GMP in-tree is required.
"config.mk" is created by Cabal when the integer-gmp package is
configured and this file is still untracked by Hadrian. This led to a
tricky configure "race" because "config.mk" is built by the
"setup-config" rule, but this rule is also used to find dependencies,
in particular the "ghc-gmp.h" header, but the creation of this file
was depending (without being tracked) on "config.mk".
Now Hadrian only builds in-tree GMP if `--with-intree-gmp` is passed
to the top-level configure script.
* in-tree GMP isn't built once for all in a fixed stage (Stage1)
anymore. It is built per stage which is required if we build a
cross-compiler
* switching between in-tree and external GMP is now supported without
having to clean the build directory first.
* "wrappers.c" now includes "ghc-gmp.h" instead of "ghc.h". It
helps ensuring that the build system generates "ghc-gmp.h".
* build in-tree GMP in "<root>/stageN/gmp/gmpbuild" and produce useful
artefacts (libgmp.a, gmp.h, objs/*.o) in "<root>/stageN/gmp"

This resolves #16809 (https://gitlab.haskell.org/ghc/ghc/issues/16809).
This patch removes the unnecessary dependency on configure-generated
flags `windowsHost`, `osxHost` and `iosHost`, using the information
provided by the module `System.Info` instead.
We also take care to use the `CrossCompiling` flag generated by the
configure script only after the latter had a chance to run.

Fixes #16187.
This patch fixes various path concatenation issues to allow functioning
builds with hadrian when the build root location is specified with an
absolute path.
Remarks:
- The path concatenation operator (-/-) now handles absolute second operands
appropriately. Its behavior should match that of POSIX (</>) in this
regard.
- The `getDirectoryFiles*` family of functions only searches for matches
under the directory tree rooted by its first argument; all of the
results are also relative to this root. If the first argument is the
empty string, the current working directory is used.
This patch passes the appropriate directory (almost always either `top`
or `root`), and subsequently attaches that directory prefix so that
the paths refer to the appropriate files.
- Windows `tar` does not like colons (':') in paths to archive files, it
tries to resolve them as remote paths. The `--force-local` option
remedies this, and is applied on windows builds.

This is a preparation for #16295: https://ghc.haskell.org/trac/ghc/ticket/16295
This commit mostly focuses on getting rid of untracked dependencies,
which prevent Shake's new `--shared` feature from appropriately caching
build rules.
There are three different solutions to untracked dependencies:
* Track them! This is the obvious and the best approach, but in some
situations we cannot use it, for example, because a build rule creates
files whose names are not known statically and hence cannot be
specified as the rule's outputs.
* Use Shake's `produces` to record outputs dynamically, within the rule.
* Use Shake's `historyDisable` to disable caching for a particular build
rule. We currently use this approach only for `ghc-pkg` which mutates
the package database and the file `package.cache`.
These two tickets are fixed as the result:
Ticket #16271: https://ghc.haskell.org/trac/ghc/ticket/16271
Ticket #16272: https://ghc.haskell.org/trac/ghc/ticket/16272 (this one
is fixed only partially: we correctly record the dependency, but we
still copy files into the RTS build tree).

This is work in progress: this commit does the right thing, but does not
yet fix the ticket.

It will remain a submodule until we are ready to merge Hadrian into the
tree.
|
| |
|
|
|
| |
Sadly subtrees haven't worked quite as well as we would have liked for
developers. See Hadrian #440.
