Patchset from Stephen Blackheath <stephen.blackheath@ipwnstudios.com>
|
|

It's now
ghc-<version>-testsuite.tar.bz2
rather than
testsuite-ghc-<version>-src.tar.bz2
which (a) makes more sense, and (b) sorts better in directory listings.

The libraries get configured during "make", so plain old "make clean"
should clean up the configure droppings.
Also fixed another wildcard/patsubst problem.
|
|
|
|
|
| |
We were applying $(wildcard ...) to the literal string
libraries/%/*.buildinfo, which of course had no matches.
|
|
|
|
|
| |
This is working towards being able to put ghcautoconf.h and
ghcplatform.h in includes/dist
|
|
|
|
| |
This is tidier, and makes it easier to clean and install them correctly
|
|
|
|
|
| |
sdist output was being redirected to $src_log, which presumably
evaluated to rc_log.

* Pass -Irts/dist/build to the C preprocessor to expose libffi headers (ffi.h and ffitarget.h) to foreign import wrappers during the building process of GHC itself.
* Install libffi headers into $(ghcheaderdir) just like any other C headers. Otherwise an installed GHC can't find them when it wants to compile foreign import wrappers.
* Include libffi headers in the bindist for the same reason.

We no longer generate them, but they may be in existing GHC trees,
so we'll keep cleaning them for a while.

With Windows 7 in a vitrual box VM on OS X, some very odd things happen
with dates and time stamps when SSHing into cygwin. e.g. here the
"Change" time is in the past:
$ date; touch foo; stat foo
Fri Dec 2 16:58:07 GMTST 2011
File: `foo'
Size: 0 Blocks: 0 IO Block: 65536 regular
empty file
Device: 540aba0bh/1409989131d Inode: 562949953592977 Links: 1

Birth: 2011-12-02 16:57:57.731469900 +0000
And if we copy such a file, then the copy is older (as determined by the
"Modify" time) than the original:
$ date; touch foo; stat foo; cp foo bar; stat bar
Fri Dec 2 16:59:10 GMTST 2011
File: `foo'

This means that make thinks that things are out of date when it
shouldn't, so reinvokes itself repeatedly until the MAKE_RESTARTS
infinite-recursion test triggers.
The touchy program, like most other programs, creates files with both
Modify and Change in the past, which is still a little odd, but is
consistent, so doesn't break make.

In particular, we now ignore .git directories

We avoid calling "rm -rf" with no file arguments; this fixes cleaning
on Solaris, where that fails.
We also check for suspicious arguments: anything containing "..",
starting "/", or containing a "*" (you need to call $(wildcard ...)
yourself now if you really want globbing). This should make things
a little safer.

The old dph-par and dph-seq CPP libraries are gone. The DPH front end libraries are now dph-lifted-*, and are only built in one way.
|
|
|
|
| |
We now make use of the ghc-packages file when making the haddock index.
|
|
|
|
|
|
| |
Cabal will use it regardless, and if people are going to use binary then
it's a lot better if they use the one that we ship, rather than
installing a second version.

We now put the libffi objects into the RTS library, rather than trying
to mangle libffi into being a ghc package itself. It would be nicer to
make it a separate library (but not a ghc package), but for now
hopefully this will get the build going through on Windows again.

There are a number of things which technically depend on GHC (e.g. if
ghc changes then Haskell files may be compiled differently, or Cabal
packages may be configured differently). However, in practice, having
a real dependency on GHC is just a pain: We normally don't want to
spend time recompiling other things while we're working on the
compiler, and even if we did, GHC will normally decide compilation
isn't needed anyway. So by default we use order-only dependencies on
GHC, i.e. GHC must exist, but if it's newer than other targets then
rebuilding is not necessary.

The *predicates* all start with "PKGS_THAT_...", e.g.:
PKGS_THAT_BUILD_WITH_STAGE0 (previously "PACKAGES_STAGE0")
PKGS_THAT_BUILD_WITH_STAGE2 (previously "STAGE2_PACKAGES")
PKGS_THAT_USE_TH (previously "TH_PACKAGES)
etc. (there are a few more)
the lists of packages to build are now consistently named:
PACKAGES_STAGE0
PACKAGES_STAGE1 (previously just "PACKAGES")
PACKAGES_STAGE2

We were putting
includes/ghcautoconf.h
includes/ghcconfig.h
includes/ghcplatform.h
into bindists twice.
|
|

|

Fixes trac #5311.
|

|
|

When we install the packages, ghc-pkg obeys umask when creating
package.cache, but for everything else we specify the permissions. We
therefore fix the permissions of package.cache afterwards.

files, so that it can refer to variables defined there. (necessary,
but perhaps not sufficient, to fix the DPH build bugs)
|
| |
|
|
|
|
| |
It now matches PACKAGES_STAGE2
|
| |
|
|
|
|
|
| |
makes it easier to remove everything built with stage1 in cases where
the build system or GHC wrongly thinks everything is up to date.
|
| |
|
|
|
|
| |
This avoids duplicating some logic around the build system.

This changes the new code generator to make use of the Hoopl package
for dataflow analysis. Hoopl is a new boot package, and is maintained
in a separate upstream git repository (as usual, GHC has its own
lagging darcs mirror in http://darcs.haskell.org/packages/hoopl).
During this merge I squashed recent history into one patch. I tried
to rebase, but the history had some internal conflicts of its own
which made rebase extremely confusing, so I gave up. The history I
squashed was:
- Update new codegen to work with latest Hoopl
- Add some notes on new code gen to cmm-notes
- Enable Hoopl lag package.
- Add SPJ note to cmm-notes
- Improve GC calls on new code generator.
Work in this branch was done by:
- Milan Straka <fox@ucw.cz>
- John Dias <dias@cs.tufts.edu>
- David Terei <davidterei@gmail.com>
Edward Z. Yang <ezyang@mit.edu> merged in further changes from GHC HEAD
and fixed a few bugs.

From
http://hackage.haskell.org/trac/ghc/wiki/Building/Architecture/Idiom/PhaseOrdering
Phase 0:
Includes: package-data.mk files for things built by the
bootstrapping compiler.
Builds: the dependency files for hsc2hs and genprimopcode. We need
to do this now, as hsc2hs needs to be buildable in phase 1's
includes (so that we can make the hpc library's .hs source
files, which in turn is necessary for making its dependency
files), and genprimopcode needs to be buildable in phase 1's
includes (so that we can make the primop-*.hs-incl files,
which are sources for the stage1 compiler library, and thus
necessary for making its dependency files).
Phase 1:
Includes: dependency files for things built by the bootstrapping
compiler.
Builds: package-data.mk files for everything else. Note that this
requires configuring the packages, which means telling cabal
which ghc to use, and thus the stage1 compiler gets built
during this phase.
Phase "":
Includes: dependency files for everything else.
Builds: Everything else.
