0122d6ed70 On second thought, disable explicitcast for list+nonlist and nonlist+list entirely, as they are not the same as list+(list)nonlist and (list)nonlist+list anyway. 2015-09-05 03:09:46 +02:00

d8649deebd nonlist + list was returning the type of the nonlist element. Fixed and added a
regression test.

Funnily enough, it was correct if explicit cast was active. Removed from explicit cast now that it's active for all.

aa74e6ed64 Sadly, Python can't represent -nan, even though llList2CSV can display it. Add a note to that effect. 2015-09-04 05:46:18 +02:00

15f1a07a72 There were more translated events. After an exhaustive analysis this is the definitive list. 2015-08-21 03:35:20 +02:00

e264260477 Two events produce different internal names than the event name itself. This was causing the reused names for these events to increase memory usage instead of reducing it. Fixed. 2015-08-21 01:20:28 +02:00

4302ea846d Don't fall through after optimizing a negable comparison, as it's folded already and the variables were incorrectly set and broke our invariants. 2015-04-21 06:11:25 +02:00

d58bc2d350 Implement library function parameter optimization.
So far only two kinds: angle in llSensor[Repeat] and null keys in functions that take a key parameter.

a19d49d193 Implement optimization of a>=const -> a>const-1 and similar, and fix cases where | -> & or a<0 -> a&0x80000000 is counter-productive.

c154d5eb0d Deal with a number of issues in some expressions.
- Move TODO of <0 to !=-1 to boolean, as it's counter-productive otherwise.
- All a!=b except list!=list are equivalent to !(a==b).
- Change a>b to b<a to simplify cases to analize.
- Proper fall-through in some spots, or return in some others where it didn't apply.
- Simplify handling of a<-2147483648 as a&0, falling through, instead of coping with it ourselves.

921955f321 Implement function overriding syntax extension, fixing a bug on the way.
The funcoverride option allows defining multiple functions with the same name, each overriding the former. That's for compatibility with Firestorm, whose optimizer does that.

While on it, fix a bug where defining a function whose name matches a library function was not reporting an error, and rename self.functions to self.funclibrary for clarity. It also brings consistency with other parts of the code and with the code documentation.
