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.
The bytecode runtime now represents code to be loaded as LongString.t,
rather than as a naked pointer to a bytecode block.
(This commit breaks Dynlink of bytecode, due to an issue about digests)
* 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
With this commit, "ocamlc -c -linkall" or "ocamlopt -c -linkall" produce object files that have the "force link" flag set. Once put in library files (.cma/.cmxa), these object files will always be linked when the library is linked, even if no definition from the object file is referenced. However, other object files in the library can still be removed if none of their definitions are referenced.
In this respect, we get finer-grained control on which object files should always be linked, typically because they contain important initialization code.
Adds the required_globals information to bytecode compilation units.
This patch also bootstrap ocamlc. The cmo format is changed by this
commit, there is no way around bootstraping here. Note that ocamldep and
ocamllex does not rely on the cmo format, so they are not present in
this commit.
Changes in tests:
* Update test/transprim/comparison_table.ml.reference:
The (opaque (global List!)) expression is not present anymore
* Update tests/no-alias-deps/aliases.cmo.reference
The output of objinfo changed

(patch by Josh Watzman)
Add absolute directory names to bytecode format for ocamldebug to use
The need for a long list of -I directives makes interactively using
ocamldebug a pain in the butt. Many folks have solved this with various
`find` invocations or even Python wrappers, but those lead to other
problems when it might include files you weren't expecting (or miss
things you were). But all of this is really annoying since the tooling
should be able to figure out itself, even heuristically, where your
source files are -- gdb gets this right, why can't we?
This patch implements one of the more important heuristics from gdb: you
typically debug on the same machine you built on, so looking for the
source files and built artifacts in the absolute paths where they were
during compilation is a good first try. We write out absolute paths into
a new structure at the beginning of the debug section and then
automatically append those directories into the load path.
This means mean that if you happen to be debugging on a machine
where the original source and build artifacts are *not* available in
their original absolute locations, things will work as before, using the
standard load path mechanism. You can also explicitly use -I to prepend
directories to the load path and override the defaults located by this
new mechanism.
I personally find this makes using ocamldebug much more pleasant :)

There seems to be a problematic interaction with backtrace collection. To test this,
make world.opt
cd testsuite
make one DIR=tests/backtrace/
This needs to be sorted out before the patch can go in again.

In PR#5925, Benoît Vaugon initially proposed the LongString module to
solve an issue with bytecode blocks of size > Sys.max_string_length on
32 bits architecture (16Mio). In PR#5957, Chet Murthy made small
changes to also fix the problem of debug information going above this
16Mio limit.
The LongString module should be reusable in other parts of the
compiler, should new 32bit-string-length issues arise.
