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. 2011-04-20 14:11:01 -05:00

Reformat for new mode syntax, step 1 Long lines were fixed in a very crude way, as I'll be following up with another reformat in a bit. 2011-09-12 04:27:30 -05:00			`fn foo<T>(o: myoption<T>) -> int {`
make --enforce-mut-vars always on, add mut annotations to remaining files 2012-03-22 10:39:41 -05:00			`let mut x: int;`
Convert alt to match. Stop parsing alt 2012-08-06 14:34:08 -05:00			`match o { none::<T> => { fail; } some::<T>(t) => { x = 5; } }`
Convert ret to return 2012-08-01 19:30:05 -05:00			`return x;`

rustc: Make the pretty printer output commas after enum variants. Update all tests accordingly. 2012-01-19 20:31:08 -06:00			`enum myoption<T> { none, some(T), }`
Reformat source tree (minus a couple tests that are still grumpy). 2011-06-15 13:19:50 -05:00
Register new snapshots, purge log_err and log_full in favour of log(...). 2011-12-22 19:53:53 -06:00			`fn main() { log(debug, 5); }`
