c7ab88cc35 Implement checking against assignments to immutable obj fields 2011-06-15 14:59:51 +02:00

0ddade3d7a Extend alias analysis to check assignments 
This is a somewhat odd place to put these checks, but the data tracked
by that pass, and the available functions, make it trivial to do such
a check there.

180db08470 Refactor expr_root in alias.rs 
It was too clunky and specific before. Now returns a vec of dereference specs
instead of a bunch of special-case information. Further accessors extract
the information they need from this vec.

05b7eb6dff Make the typechecker check that dynamically sized arguments are passed by alias 
Before, this would cause an assertion failure in trans.

f24408d89a Don't error when trans_lval is called on a non-lval 
This allows directly calling a function expression, or the
result of an alt/if/block expression.

d1857d30fc This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc). 
This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.

d65ad8c31c Change decl to local in expr_for and expr_for_each 
Since the decl in a for or for-each loop must always be a local
decl, I changed the AST to express this. Fewer potential match
failures and "the impossible happened" error messages = yay!

698c6406ba Reject programs with unsatisfied predicate constraints 
Generate appropriate constraints for calls to functions with
preconditions, and reject calls where those constraints don't
hold true in the prestate.

...by which I mean that it works for one test case :-)

774c6d0198 Friendlier error message for break outside a loop 
The typechecker should really check for this, but at least now
there's an error message rather than an inexhaustive match failure
in trans.

e5eacf8ea9 Use RHS type when translating assignments 
In code like "auto foo = fail", a type gets inferred for foo
depending on how it's used. However, fail still has type _|_ and
still should be treated that way: particularly, its value shouldn't
be copied. Fixed trans to reflect that.
