19255bce2c split the test file into several testfiles 2020-12-12 12:04:37 +01:00

1860dc91f8 multifile support: guile compile.scm a.ml b.ml c.ml -o foo.byte 
The declarations of each file are placed into a module whose name is
derived from the filename in the standard OCaml way.

In particular, this changes slightly the semantics of single-file
invocations: now foo.ml is interpreted as if its declarations were
wrapped into a Foo module. The observable behavior of program does not
change, of course, as we only observe the side-effects of the
evaluation.

(This should not change the compilation either, as structure items,
even nested, are compiled into globals. I checked that the generated
bytecode programs for hello.ml keeps the same size.)

c61d94ed0e turn hello.ml into a more convenient test 
Now you can run

    make compiler-test

from the root of the repository to run hello.ml, and compare its
output to a version-controlled reference output.

If the output changes for good reasons, you can update the reference
file with

    make compiler-test-promote

Note: it may sound unpleasant to version-control program-generated
outputs, but in fact (as long as those outputs are kept
human-readable) this is an excellent idea for testing: it means that
any change to the testing output will be part of the commits/diffs,
making it easier for reviewers to understand the impact of a change.

eae8c877fe update the ocaml-src submodule to track the maintenance 4.07 branch 
Building 4.07 (and 4.08) was broken on recent GCC versions; I just
pushed a commit to the maintenance branch of 4.07 to fix this, so that
I can build on my machine.

1bde4c5d88 environments contain "bindings", export bindings-get 
This is a new abstraction/concept in the codebase: the vhashes that
contain visibility information and a definition are called
"environment bindings".

For now there is only an accessor, bindings-get.
