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 moves the configure-generated parts of Makefile.common to a
separate (generated) Makefile, allowing Makefile.common to be a normal
Makefile.
OCaml's build system Makefile's now include Makefile.build_config (which
itself includes Makefile.config) but Makefile.config is still installed
as before. This allows configure to generate variables which are
specific to the build process and are not intended to be exported to the
installation.
The instrumentation code in the instrumented runtime was replaced
with new APIs to gather runtime statistics and output them in a new format
(Common Trace Format).
This commit also exposes new functions in the Gc module to pause or resume
instrumentation during a program execution (Gc.eventlog_pause and
Gc.eventlog_resume).
The issue #9050 comes (partly) from #2281 forgetting to add the
compilerlibs/ocamlmiddleend archives in the installation target. The
present patch should solve this issue once and for all, by using
a wildcard to install all archives that have been built in
compilerlibs/, instead of using a manual listing.
Compared to trunk, the following extra files are installed in
$(LIBDIR)/compilerlibs: ocamlmiddleend.{a,cma,cmxa}. There are no
other changes in the installed-files list.
(make -C ocamltest) will run the first rule of the ocamltest Makefile,
which happens to be the 'all' rule. This is not robust to the addition
of new rules in some of the included Makefile, and indeed a previous
version of the previous commit broke it inadvertently.
The Git configuration value ocaml.configure is now passed to the
configure script's arguments before $@ if (and only if) OCaml is being
configured from a Git clone.
This allows, for example:
- Developer-specific preferences (e.g. `--disable-ocamldoc` or
`--disable-debug-runtime`)
- Automatic use of autoconf cach files (-C option)
It is implemented by inserting a test at the top of `configure`, which
is bypassed if `.git` doesn't exist.
This commit makes it possible to build the OCaml compiler according to
its configuration by simply runnning make. There is no need to specify
neither world nor world.opt explicitly, although the two targets
remain available.
This commit also introduces (and starts making use of) the
NATIVE_COMPILER build variable whosse value is true when the native
compiler is enabled and false otherwise.
This commit defines five default argument modules in
Main_args.default. Those modules provide a default implementation
for the argument of ocaml, ocamlnat, ocamlc, ocamlopt, ocamldoc,
ocamlcp, ocamloptp, and expect_test.
Grouping together those implementations allow to share as much as
possible similar implementation across executables. It should make
easier to keep synchronized the various implementation, or reuse
those implementation in alternative drivers.
Separate the description of the IR from the transformations
performed on it by moving type declarations from linearize.ml
into their own file, called linear.ml.
Makefile.dev is only included if a Git clone is detected.
make evaluates macros in target specifications when the Makefile is
read, which meant that the build-all-asts target caused `git ls-files`
to be called on every invocation of make. This tweaks it to be a
recursive call to make which puts the $(AST_FILES) macro in the recipe
where it is only evaluated when the target is requested.
This commit makes e.g. make -s world.opt completely
silent when everything works, in order to increase the visibility of
any unexpected message occurring during the build.
This will be useful for instance during CI, in particular it should
make it easier to catch undefined build variables.
The implementation is straightforward. The OCAMLLEX_FLAGS variable is
defined in Makefile.common.in and then used consistently by all
lexing recipes.
In addition, in tools/Makefile, the two rules producing the lexers
from cvt_emit.mll and make_opcodes.mll have been replaced by a
pattern-rule and the useless .SUFFIXES target has been removed.
Previously, if the native-code compiler is not supported
(e.g. because configure doesn't recognize the target architecture,
or is run with --disable-native-compiler), "make world.opt"
fails late and with a mysterious error message
(a warning about undeclared C functions in runtime/roots_nat.c
or runtime/backtrace_nat.c, typically).
This commit ensures that "make world.opt", "make opt" and "make opt.opt"
fail immediately with a meaningful error message if the native-code
compiler is not supported.
Note: in "world.opt", make sure that "checknative" is run, and only
then "coldstart"; don't run them in parallel.
