When a module is loaded from bytecode and then the value of
`use-compiled-file-paths' changes, an attempt to load a submodule
would fail, because source isn't used if the main module is
already declared, and the bytecode code is not used according to
`use-compiled-file-paths'. Make the bytecode path stick when it
is used once, so that submodule loads succeed, and make it work
even with `namespace-module-attach'.
The module-attach part of this protocol requires a change to the
API of a module name resolver: the notification mode gets two
arguments, instead of one, where the second argument is an
environment.
The libraries moved were:
- mzlib/control => racket/control
- mzlib/date => racket/date
- mzlib/deflate => file/gzip
- mzlib/inflate => file/gunzip
- mzlib/port => racket/port
- mzlib/process => racket/system
- mzlib/runtime-path => racket/runtime-path
- mzlib/shared => racket/shared
- mzlib/unit => racket/unit
- mzlib/unit-exptime => racket/unit-exptime
- mzlib/zip => file/zip
The old modules in mzlib are now pointers to the
new modules. These are all modules that were already
redirected in the documentation.
This convention makes it easier to deal with a set
of ".rkt" files that implement tests, while a `test'
module implements a `main'-like split for some of the
files.
This addition triggered several other changes:
* -k for a Mac OS X embedding is now relative to the __PLTSCHEME
segment (which means that executables won't break if you strip
them, for example)
* the command-line no longer has a limited size for Mac OS X
launchers and embedding executables
* Mac OS X GUI and Windows launchers record the creation-time
collection path, unless they are created as "relative" launchers
In particular, allow a pair of a relative-to directory and a base
directory. Paths that syntactically extend the base directory are
recorded as relative to the relative-to directory (which must
syntactically extend the base directory).
The compilation manager now sets the parameter to a pair with
the base directory as the main collection directory, if the source
file's path extends that directory's path.
This generalization solves problems created by cross-module inlining,
where the source location of a procedure in bytecode can now be in a
different file than the enclosing module's file.
Also add a test that checks whether the build directory shows up
in any ".zo", ".dep", or documentation ".html" files.

Inline only trivial functions, such as `(empty? x)' -> `(null? x)',
to avoid generating too much code.
Bytecode includes a new `inline-variant' form, which records a
version of a function that is suitable for cross-module inlining.
Mostly, the variant let the run-time system to retain a copy
of the bytecode while JITting (and dropping the bytecode of)
the main variant, but it may be different from the main variant
in other ways that make it better for inlining (such a less loop
unrolling).
As variables are dropped for lifted functions, the bitmap
for flonum closure variables was not shifted down by the
number of dropped variables.
Closes PR 12259
Macros and other tools that need syntax privilege used
`(current-code-inspector)' at the module top-level to try to
capture the right code inspector at load time. It's more
consistent to instead use the enclosing module's declaration-time
inspector, and `var-ref->mod-decl-insp' provides that. The
new function works only on references to anonymous variables,
which limits access to the inspector.
The real function name is longer, of course.
The main change is to use C99 flexible array declarations
in structs, instead of declaring single-element arrays.
There are still a few -Wtautological-compare warnings
in 3m due to marco expansion.
Although the ".plt" format is going to be replaced, the format is
currently viable for distributing collections, and I have wanted
a raw `unpack' command for a while. It was useful today to fix
problems with `raco pack' and collection links.
The JIT and bytecode compiler disagreed on the definition of
"constant". Now there are two levels: "constant" means constant across
all instantiations, and "fixed" means constant for a given instantation.
The JIT uses this distinction to generate direct-primitive calls
or not. (Without the distinction, a direct jump to `reverse' could
be wrong, because `racket/base' might get instantiated with the
JIT disabled or not.)
Also, fixed a bug in the JIT's `vector-set!' code in the case that
the target vector is a top-/module-level reference that is ready,
fixed, or constant.
