We had been maintaining two copies of these notes, this change attempts to
merge them into one set. The cononical location for these notes is here in
compiler/notes/, they will be removed from the www repository.
I've also updated a number of URLs.
compiler/notes/allocation.html:
compiler/notes/bootstrapping.html:
compiler/notes/coding_standards.html:
compiler/notes/compiler_design.html:
compiler/notes/gc_and_c_code.html:
compiler/notes/glossary.html:
compiler/notes/release_checklist.html:
compiler/notes/reviews.html:
compiler/notes/todo.html:
compiler/notes/work_in_progress.html:
Merge in differences with the versions of these files in the www
repository. Most differences are trivial.
compiler/notes/bytecode.html:
compiler/notes/c_coding_standard.html:
compiler/notes/developer_intro.html:
Add files that were missing from the main repository but were on the
website.

<h2> Changes that don't bootstrap </h2>
|
|
|
|
<p>
|
|
|
|
Sometimes changes need to be made to the Mercury system that mean
|
|
previous versions of the compiler will no longer successfully compile
|
|
the new version.
|
|
<p>
|
|
|
|
Whenever anyone makes a change which prevents bootstrapping with a
|
|
previous version of the compiler, they should add a cvs tag to all the
|
|
files in the relevant directories <em>before committing</em>, and
|
|
mention this tag in the log message. The tag should be of the form
|
|
bootstrap_YYYYMMDD_<short_description_of_change>.
|
|
<p>
|
|
|
|
The rationale for the cvs tag is that it allows machines to be
|
|
bootstrapped (if they didn't manage to do it in a daily build)
|
|
by doing `cvs update -r<tag>' on the relevant build directory.
|
|
After that compiler has been installed, a `cvs update -A' will remove
|
|
the cvs sticky tags.
|
|
<p>
|
|
|
|
Optionally, a test should be added to the configuration script so
|
|
that people installing from CVS don't use an outdated compiler to
|
|
bootstrap. Practically this may be difficult to achieve in some cases.
