Brian Anderson
fbfd8552ab Return a better result from blocks. Closes issue #377 
Blocks return in a copy of the result of their ending expression, not the
direct result of the ending expression, as that may be a local variable which
gets zeroed by drop_slot.

387a8888ee Fix get_os and get_arch 
get_os and get_arch were failing to return a value in the error
case; they were also assuming that strings are indexed from 1. No
idea how they ever worked, but anyway, fixed.

b42bb2cff2 Two tests that the typechecker correctly unifies type arguments in patterns with their expected tag types 2011-05-16 16:59:30 -07:00
Tim Chevalier
971b5d5151 Started adding support for return checking and non-returning function annotations 
* Reorganized typestate into several modules.

* Made typestate check that any function with a non-nil return type
  returns a value. For now, the check is a warning and not an error
  (see next item).

* Added a "bot" type (prettyprinted as _|_), for constructs like be, ret, break, cont, and
  fail that don't locally return a value that can be inspected. "bot"
  is distinct from "nil". There is no concrete syntax for _|_, while
  the concrete syntax for the nil type is ().

* Added support to the parser for a ! annotation on functions whose
  result type is _|_. Such a function is required to have either a
  fail or a call to another ! function that is reached in all control
  flow paths. The point of this annotation is to mark functions like
  unimpl() and span_err(), so that an alt with a call to err() in one
  case isn't a false positive for the return-value checker. I haven't
  actually annotated anything with it yet.

* Random bugfixes:

* * Fixed bug in trans::trans_binary that was throwing away the
    cleanups for nested subexpressions of an and or or
    (tests: box-inside-if and box-inside-if2).

** In typeck, unify the expected type arguments of a tag with the
   actual specified arguments.

7647b838a1 Remove reserved word tests (since reserved words were removed) 
Ping me if you disagree, but I think that in a language that's as
in-flux as rust currently is, it is silly to try and enforce a single
future-compatibility. The reserved words didn't work well with the
parser refactor, so I dropped them for the time being. We can,
eventually, bring them back as type-only reserved words.

ae26b775b4 Implement module namespaces

tokenizer/parser still needs to be taught to be more careful in

module names.

358a1aeec9 Keep resolve data in external hash table, rather than embedded defs 
One step closer to removing fold and having a single, immutable AST.
Resolve still uses fold, because it has to detect and transform
expr_field expressions. If we go through on our plan of moving to a
different syntax for module dereferencing, the parser can spit out
expr_field expressions, and resolve can move to walk.

(I am truly sorry for the things I did in typestate_check.rs. I expect
we'll want to change that to walk as well in the near future, at which
point it should probably pass around a context record, which could
hold the def_map.)

"check" must be a manifest call to a special kind of function
declared with the new "pred" keyword instead of "fn". Preds must
have a boolean return type and can only call other preds; they
can't have any effects (as enforced by the typechecker).
The arguments to a predicate in a check expression must be
slot variables or literals.

06f0713906 Mark valgrind's _qzz_res as unused to silence warnings on gcc 4.6. 
This applies c11675 by Julian Seward from valgrind trunk
(svn://svn.valgrind.org/valgrind/trunk) to rustrt's included
copies of memcheck.h and valgrind.h, effectively backporting
the fix from the unreleased 3.6.2. The commit simply applies
the gcc 'unused' attribute to the relevant declarations.

This change allows compilation of the runtime code under
gcc 4.6 with -Werror, as the makefile currently requests.

a3ff02f126 Split start into rustc and rustboot versions. This introduces a bit of 
duplication, but we will hopefully drop the rustboot one soon.

This is also a preparation for changing the rustc one to have the activate glue
return to the exit glue which will then call the main function.

This (returning to the function that calls main) matches what happens when
loader stats a program or a new thread. It lets gdb produce good backtraces
and should help with EH too.

While those unexported items can't be used by name outside the module in which
they are defined, they can be used as a sort of ADT.

aa25f22f19 Use different syntax for checks that matter to typestate 
This giant commit changes the syntax of Rust to use "assert" for
"check" expressions that didn't mean anything to the typestate
system, and continue using "check" for checks that are used as
part of typestate checking.

Most of the changes are just replacing "check" with "assert" in test
cases and rustc.

93845d0bae Fix nested patterns in rustboot 
The code for taking pattern-bound variables was being interspersed
with pattern code, so that if a nested pattern failed partway through,
a variable would be taken but never dropped (because the drop code
is inside the block representing the action for the pattern). For
example, in the pattern foo(?i, bar(some[t](_)), _), if the scrutinee
was foo(x, bar(none[t]), y), the variable i would be taken but never
dropped. The patch fixes this bug.

0190ebfe07 Support all expression forms in typestate 
Added support for self_method, cont, chan, port, recv, send, be,
do_while, spawn, and ext; handled break and cont correctly.
(However, there are no non-xfailed test cases for ext or spawn in
stage0 currently.)

Although the standard library compiles and all test cases pass with
typestate enabled, I left typestate checking disabled as rustc
terminates abnormally when building the standard library if so,
even though it does generate code correctly.

7c4f8cb459 Further work on typestate_check 
Lots of work on typestate_check, seems to get a lot of the way
through checking the standard library.

* Added for, for_each, assign_op, bind, cast, put, check, break,
and cont. (I'm not sure break and cont are actually handled correctly.)

* Fixed side-effect bug in seq_preconds so that unioning the
preconditions of a sequence of statements or expressions
is handled correctly.

* Pass poststate correctly through a stmt_decl.

* Handle expr_ret and expr_fail properly (after execution of a ret
or fail, everything is true -- this is needed to handle ifs and alts
where one branch is a ret or fail)

* Fixed bug in set_prestate_ann where a thing that needed to be
mutated wasn't getting passed as an alias

* Fixed bug in how expr_alt was treated (zero is not the identity
for intersect, who knew, right?)

* Update logging to reflect log_err vs. log

* Fixed find_locals so as to return all local decls and exclude
function arguments.

* Make union_postconds work on an empty vector (needed to handle
empty blocks correctly)

* Added _vec.cat_options, which takes a list of option[T] to a list
of T, ignoring any Nones

* Added two test cases.
