We want to start allowing more information in the payload of
[@tailcall] attributes (currently no payload is supported), for
example we could consider using [@tailcall false] to ask the code
generator to disable a tail call.
A first required step in this direction is to use a custom datatype to
represent the tail-call attribute, instead of a boolean. This is
consistent with the other application-site
attributes (inline_attribute, specialise_attribute, local_attribute),
so it makes the code more regular -- but the change itself is
boilerplate-y.
Lambda and Clambda distinguish Const_int from Const_pointer only so
that they can pass the information to Cmm. But now that that
Const_pointer is gone from Cmm (#9578), there's no need for the
distinction in Lambda either.
This PR requires a bootstrap, because the .cmo format changes:
Lambda.structured_constant has one fewer constructor. The bootstrap
is in the following commit.
This PR was tested with also the -dsel, -dlinear output (also fixed to
not-print locations), but the output is architecture-dependent so this
part of the test was removed.
* Various file moves in the middle end: this is the first stage of improving separation between the middle end and backend.
* Creation of file_formats/ directory (with associated file moves) to hold the definitions of compilation artifact formats.
* Creation of lambda/ directory (with associated file moves) to hold Lambda language definition files, transformation passes and construction passes from Typedtree.
* Disable (hopefully temporarily) dynlink, debugger and ocamldoc for the dune build.

The only remaining user was [Predef], which was bumping the counter by
999 to allow cmis to remain compatible if new predefs were defined.
This commit removes that use by making sure that every ident defined in
predef.ml is marked as predef and use a different stamp counter as user
defined idents. That way idents in cmi always start at 1, no matter how
many predefs there are.
Stamps on predef aren't strictly necessary: predefs names are unique.
However, predef idents comparison is just faster with stamps.
- Ident.create now takes a scope as argument
- added Ident.create_var to use when the scope doesn't matter
- the current_time and the current_level are unrelated as of this
commit. But one has to remember to bump the level when creating new
scopes.
- inline Pervasives in Stdlib and re-add Pervasives as a deprecated
module that aliases all elements of Stdlib except the stdlib modules.
- remove special case for Stdlib.Pervasives in printtyp.ml
Except the OCAMLPARAM stuff, as that runs before the command line
warning settings are even parsed, so while they are reported using the
normal warnings code, they don't look like normal warnings.
