Tests for while loops that may invalidate constraints Wrote some small test cases that use while loops and moves, to make sure the poststate for the loop body gets propagated into the new prestate and deinitialization gets reflected. Along with that, rewrite the code for intersecting states. I still find it dodgy, but I guess I'll continue trying to add more tests. Also, I'll probably feel better about it once I start formalizing the algorithm. 2011-06-27 20:12:37 -05:00			`fn main() {`

Reformat for new syntax 2011-07-27 07:19:39 -05:00			`let y: int = 42;`
new liveness pass to supercede last_use / initedness 2012-05-19 07:52:01 -05:00			`let mut x: int;`
Tweak some test cases and add a few new ones 2012-03-10 22:38:03 -06:00			`loop {`
Register new snapshots, purge log_err and log_full in favour of log(...). 2011-12-22 19:53:53 -06:00			`log(debug, y);`
improve liveness so it reports unused vars / dead assignments doesn't warn about pattern bindings yet though 2012-05-23 22:53:49 -05:00			`while true { while true { while true { x <- y; copy x; } } }`

Reformat This changes the indexing syntax from .() to [], the vector syntax from ~[] to [] and the extension syntax from #fmt() to #fmt[] 2011-08-19 17:16:48 -05:00			`}`
