When building for the first time, the only requirement is that generated
header files have been built (jumptbl.h, version.h and opnames.h).
Detailed dependency information is only required when headers have been
edited.
COMPUTE_DEPS in Makefile.config controls whether C dependency
information should be generated on a per-file basis. This variable is
controlled by a new --disable-dependency-generation in configure which
is enabled for Git checkouts and disabled for tarballs (i.e. releases).
The Microsoft C compiler (cl) cannot generate dependencies in a
consistent way which we can consume, so for a Git checkout configure
searches for an additional C compiler in order to compute dependencies.
This is obviously not required for a user-build.
As a result, the MSVC port can now safely run make alldepend, since only
OCaml dependency information is committed to the repo after this change.
CI does not need to waste time testing the dependency information,
because it only tests a single build. A single Travis job has been added
which tests the build system code to generate the dependency information
(and provides a single `make -j` run in CI, although Inria's CI also
tests parallel building continuously).
This commit is a follow-up to 123334881a.
Its purpose is to make the environments module abstract again,
by moving the parsing mechanism in its own module.
Consequently, the environments module can be linked earlier again (as
was the case before the commit mentionned above) and can thus be
used in other modules.
When a toplevel test consists in more than one file, it is necessary to
compile the auxiliary files so that they can then be loaded into the toplevel.
This method stores for each toplevel the compiler to use to do this.
This module contains types describing test results and functions to
build and use them.
Before this commit, only successful actions were returning an environemnt.
Starting from this commit, actions always return an environemnt, no matter
their result.
This will make it possible to write negations over tests.
This commit contains:
- The initial version of the tool itself, in the ocamltest directory
- The required additions to the main .gitignore and .merlin files.
The integration of ocamltest in OCaml's main build system and its use
in the testsuite are not part of this commit.
Credits go to David Allsopp for
- Extending the computation of ocamlsrcdir to the Windows case
- Making ocamltest compile when flexlink
is being bootstrapped.
