December 21, 2010 [dmd-internals] Next round of ICE and wrong-code patches | ||||
---|---|---|---|---|

These patches have built up while waiting for the 2.051 to be cleared for release. //Trivial: 5242 self referencing template constraint crashes compiler // These two are back-end optimizer bugs, though they are only incorrect asserts. I think the second one is quite interesting, it shows the optimiser has // an O(n^^2) performance for comma expressions. If you ever find the optimiser is slow, I think there's an excellent chance that that is the reason. 4379 ICE(blockopt.c): foreach over huge tuple, only with -O 3681 ICE(go.c): when function takes too long to optimize, only with -O. 5025 ICE(cast.c) shared struct literal 5090 ICE(todt.c) struct literal initializing zero length array 4389 ICE(constfold.c, expression.c), or wrong code: string~=dchar in CTFE ---> this one is fairly large, I can commit it if you prefer // mitigation only. 4860 Taking delegates to a member function broken if method is also aliased in from a base class |

Posted in reply to Don Clugston | Thanks, Don. I have a whole backlog of stuff to merge in as well.
