99a697b56a Add support for upper-case hex and binary output to #fmt. 
Only works for uints at present. Necessitated the addition of _str.to_upper.

7c6e6fc5d4 Make expr_while work in typestate_check 
Also did some refactoring in typestate_check. All test cases in
compile-fail that involve uninitialized vars now fail correctly!
(All eight of them, that is.)

e7b8db2e63 Enable alias analysis and the function attributes pass. 
The C API extension is already upstream, we can drop the local copy once
the bots are updated.

63e87c102d typestate_check can now handle expr_block, expr_if, and expr_binary 
(caveat for the latter: it assumes that binary operations are strict;
a TODO is to detect or and and and correctly reflect that they're lazy
in the second argument). I had to add an ann field to ast.block,
resulting in the usual boilerplate changes.

Test cases that currently work (if you uncomment the typestate pass
in the driver) (all these are under test/compile-fail):

fru-typestate
ret-uninit
use-uninit
use-uninit-2
use-uninit-3

e11e8754de rustc: Add "float" as a type to the pretty printer 2011-04-12 15:10:39 -07:00

d7e8818414 Further work on typestate. Handles expr_rec and expr_assign now. 
Also changed the ts_ann field on statements to be an ann instead,
which explains most of the changes.

As well, got rid of the "warning: no type for expression" error
by filling in annotations for local decls in typeck (not sure whether
this was my fault or not).

Finally, in bitv, added a clone() function to copy a bit vector,
and fixed is_true, is_false, and to_str to not be nonsense.

1af3174fe3 Move to single-uint file-position representation. 
This makes passing them around cheaper. There is now a table (see
front/codemap.rs) that is needed to transform such an uint into an
actual filename/line/col location.

Also cleans up the span building in the parser a bit.

9c001af07c Implemented computing prestates and poststates for a few expression forms. 
The typestate checker (if it's uncommented) now correctly rejects a
trivial example program that has an uninitialized variable.

d2d42fd4c7 Make block results work for generic types 
I think just about every type can be used as a block result now. There's quite
a proliferation of tests here, but they all test slightly different things and
some are split out to remain XFAILed. The tests of generic vectors are still
XFAILed because generic aliased boxes still don't work in general.

1092bbfff0 Support for self-calls that take arguments. 
Nicer parsing of self-calls (expr_self_method nodes inside expr_call
nodes, rather than a separate expr_call_self) makes typechecking
tractable.  We can now write self-calls that take arguments and return
values (see: test/run-pass/obj-self-*.rs).

'rustc -ls [cratelib]' will now dump out a list of symbols defined by
the crate, as well as a short description of what they are.

d678dad434 Fix problem in metadata writer 
It was creating non-multiple-of-four section sizes, which, for some
reason, presumably by LLVM, were clipped, rather than padded, to be a
multiple of four.
