The large diff in boot/menhir/parser_menhir.ml comes from the fact
that the token list is now included in it, instead of being merely
a reference to the yacc parsers' Parser.token type.
The goal of this change is to avoid conflicts encountered by
compiler-libs users that would also use their own MenhirLib runtime
for their own parsers.
I first tried to implement a solution to this module-name-conflict
issue using module aliases and -open, but this proven too fragile and
too difficult to get right.
* Fix MPR#7726 by re-checking recursive modules in signatures after substitution
* Check module applications when translating types in Typetexp
* Check all results of functor applications lazily
* Reduce the overhead of checking module types by building the environment lazily
These options allow to control whether identifiers are made unique by
appending a stamp to them when dumping intermediate representations or not.
The default is to print the stamp, as is done currently.
The "-dno-unique-ids" option is useful e.g. to simplify the comparison
between a produced intermediate reprsentation (-dlambda, say) and the
expected one, in the context of the testsuite, for instance.
Previously, there was a dedicated traversal of the Parsetree to
collect and report all ocaml.ppwarning attributes. This approach has
the drawback that ocaml.warning settings for the current scope around
the ocaml.ppwarnign attribute were not taken into account.
Thanks to previous commits, we have a specific place in the code were
all attributes go through. So we re-use it to detect ocaml.ppwarning
attributes, completely avoiding the dedicated traversal and the
drawback mentioned above.
* Complier: -compat-32 flag when building cmo/cma.
Compiler: refactor -compat-32 support
Update Changes
Complier: more -compat-32 checks in emitcode.
* add tests for the -compat-32 flag
This commit moves:
- config/m.h to byterun/caml/m.h
- config/s.h to byterun/caml/s.h
Consequently, m.h and s.h now get installed alongside other
OCaml header files.
This commit also updates the .depend files, introducing updates in the
dependencies which are not consequences of this commit itself.
Deprecation warning (3) is currently only reported when directly
accessing a component marked with the deprecated attribute; but it is
missed when we coerce the signature contaning the deprecated component
to a signature without the attribute.
This commit adds the required machinery to detect such cases
and report the same warning. (An alternative design could be
to introduce a new warning for that purpose.)
Some of the new machinery could be used for other purposes:
- During the inclusion check, keep the location that would used in
the error message if the check fails.
- Warnings can now hold extra "sub-locations" (and associated
messages).
The code in this commit was written by Marcell Fischbach & Benedikt Meurer.
See [Mantis#5324](http://caml.inria.fr/mantis/view.php?id=5324) for some
context.
The code (which was originally written against 3.12) was ported to trunk by
doing
```bash
git clone https://github.com/bmeurer/ocaml-experimental/
cd ocaml-experimental
git diff master...linear-scan-register-allocator > t.diff
```
and then applying the diff by hand.
