Persistent_env is a new module that handles the relation between the
type-checking state and the "persistent" typing information laying in
.cmi files on the filesystem. In particular, it handles the collection
and production of CRC information for the .cmi files being read and
written to the filesystem; the using modules (in our case, only Env)
are in charge of turning the cmi files into higher-level information
(components and signatures).
Persistent_env exposes a type `'a t` of a persistent environment,
which acts as a mutable store of `'a` values. There is no global state
in the module itself: while Env (and thus the OCaml type-checker) uses
a single global persistent environment, it should be possible to
create several independent environments to represent, for example,
several independent type-checking sessions.
- Add a Load_path module which caches files lookup
- Instead of falling back to the external environment, allow to
declare in the environment that a module comes from the external
world. This allows persistent structures to shadows non-persistent
ones
This change should be a refactoring no-op.
Before, a DEPFLAGS variable existed in some makefiles to contain
include directories to be passed to ocamldep invocations, but no
support for easily adding command-line flags to ocamldep was available
(invocations would systematically use -slash, which was duplicated
across callsites).
With this PR, a new DEPINCLUDES variable contains the include
directories, and DEPFLAGS is repurposed to contain other command-line
flags for the tool -- currently "slash".
get_unboxed_type_representation is used in several other modules, and
split into its own Typedecl_unboxed unit.
(pair-programming with Gabriel Scherer)
used by `make build-all-asts` and related commands.
Indeed, the idea is to check that the ASTs do not change when the parser is
modified -- the parser's source itself, if included, would always produce a
false positive.
- The code responsible for printing Syntaxerr errors is moved to the
Parse module (so that it can depend on the variable printer in
Pprintast).
- Pprintast becomes a dependency for a few tools that link some
compiler modules in an ad hoc way (they would better be implemented
in terms of compiler-libs).
In order to prepare the transition to autoconf, this commit moves the
configuration Makefile out of the config directory which will disappear
and gives it the name it will have once intstalled, namely Makefile.config.
This subdirectory was used to store experimental patches on some older
version-control system where branching (or discussing branches?) was
inconvenient. It doesn't make much sense anymore now, and getting rid
of it simplifies a couple places that had to grow around it.

If an error occurs while making flexlink.opt, the bytecode image was not
restored. It's now restored even if an error occurs while building the
native code image.
Some Makefiles were using export to set OCAML_FLEXLINK "globally" while
others set a variable FLEXLINK_ENV and set the environment explicitly.
All Makefiles now use FLEXLINK_ENV and also only invoke it on linking
commands (rather than, for example, all invocations of ocamlopt).
