inside the same collection so this file can (when other
things aren't too different) be used in a version of racket
that doesn't generally have the tests
Track fixnum results in the same way as flonum results to enable
unboxing, if that turns out to be useful. The intent of the change,
though, is to support other types in the future, such as "extnums".
The output `raco decompile' no longer includes `#%in', `#%flonum',
etc., annotations, which are mostly obvious and difficult to
keep in sync with the implementation. A local-binding name now
reflects a known type, however.
The change includes a bug repair for he bytecode compiler that
is independent of the generalization (i.e., the new test case
triggered the old problem using flonums).
The `lazy-require' form expands to `define-runtime-module-path-index',
whch doesn't work right at phase levels other than 0. Work around the
problem by generating a submodule to hold the
`define-runtime-module-path-index' form.
This repair fixes `raco exe' on certain uses of `match', which in turn
uses `lazy-require' at compile time.
Also, use `register-external-module' to generate appropriate
dependencies on lazily loaded modules.
The JIT was pessimistically using 64-bit jumps for long branches
or any jump between code that is allocated at different times.
Normally, though, code allocation stays within the same 32-bit
range of the heap, so stick to 32-bit jumps until forced by
allocation addresses to use 64-bit jump targets.
Commit ffe45ecce had introduced a regression with some
polymorphic functions imported between typed modules due to
miscommunicated variance information.
correct-xexpr?. Inverted the logic and replaced the
continuation-passing style with simpler test-for-error logic. Also
corrected typo in attribute symbol checker that could otherwise lead
to a contract error. (taking the cadr of a non-cadrable value)
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
In `(if (pair? x) E1 E2)', convert `(car x)' in E1 to
`(unsafe-car x)', and similarly for `(cdr x)'. Also,
`(begin (car x) (cdr x))' converts to `(begin (car x)
(unsafe-cdr x))' since `(car x)' implies a `pair?' test
on `x'.
typing them in, in the module language test suite
this speeds it up; going from 140 to 105 seconds on my (mac)
machine. (drdr was taking 240 or so seconds, tho)
