Bob Nystrom 76ac818eaf Subscript setters. 2013-12-21 09:37:59 -08:00
Bob Nystrom 6fdcf800a8 Do a bit more documentation. 2013-12-21 09:15:30 -08:00
Bob Nystrom f2b036420d Fix a bunch of test TODOs. 
- Added a bunch of tests.
- Removed some TODOs for stuff that's already done.
- Made list literals handle newlines better.
 2013-12-20 12:42:11 -08:00
Bob Nystrom 315ed1c425 Make heap usage configurable. 2013-12-20 07:41:35 -08:00
Bob Nystrom e83d0bb360 Setters! 2013-12-20 07:05:31 -08:00
Bob Nystrom 61e745d548 Bump default heap size up. 
This makes the binary_trees benchmark much faster.
 2013-12-20 07:05:13 -08:00
Bob Nystrom b937597ea7 Make benchmarks score based instead of time based. 2013-12-20 07:04:04 -08:00
Bob Nystrom f9099791a1 Add another test for constructor syntax. 2013-12-19 09:10:45 -08:00
Bob Nystrom 4d67f2270a Use more conventional syntax for constructors. 
They are now invoked like "new Foo".
Also, superclass constructors are now much less semantically
and syntactically weird. Since the instance is created before
any constructor is called, there's no point in time where the
instance isn't there.
 2013-12-19 07:02:27 -08:00
Bob Nystrom b880b17db9 Add TODO about resolving ctors. 2013-12-18 07:39:46 -08:00
Bob Nystrom e7cf8ffe2e Make method_call benchmark use inheritance. 
This also fixes a bug where constructors weren't being bound
correctly, and eliminates some unneeded instructions when
compiling ifs.

I also tweaked the other method_call languages to match Wren's.
Since Wren needs to do a super call to get to the parent _count,
the other languages do now too.

This is nice too because it means we're benchmarking super 
calls.
 2013-12-18 07:37:41 -08:00
Bob Nystrom caafa96252 More work on docs. 2013-12-17 09:39:26 -08:00
Bob Nystrom 271fcec81b Start getting superclass constructors working. 
This also means the metaclass inheritance hierarchy parallels
the regular inheritance chain so that the subclass can find
the superclass constructor.
 2013-12-17 09:39:05 -08:00
Bob Nystrom 70e548657e Don't allow "super" outside of methods. 2013-12-15 22:08:40 -08:00
Bob Nystrom 5fb2d5af71 Use flexible array for upvalues in closure. 2013-12-15 22:02:22 -08:00
Bob Nystrom 9e67cd3220 Use stdbool.h and bool for booleans. 2013-12-14 23:41:23 -08:00
Bob Nystrom f5e4f95069 Write some more scope edge case tests. 2013-12-14 16:36:19 -08:00
Bob Nystrom 7fe60499db Get rid of my name from TODOs. Anyone can do them. 2013-12-14 15:28:18 -08:00
Bob Nystrom 5c807c0ec5 Track memory during deallocation correctly. 
It used to subtract the number of bytes during deallocation, but
that required knowing the size of an object at free time. That
isn't always available. The old code could read a freed object
while doing this. Bad!

Instead, this tracks how much memory is still being used by
marked objects. It's correct, and is also a bit less code and
faster.
 2013-12-14 14:17:16 -08:00
Bob Nystrom 3fd7fa56fb Inline wrenObjectToValue(). 
Seems to give a slight speed bump. Inlining the wrenIs___
functions doesn't seem to help (may make it a bit worse.)
 2013-12-14 11:34:49 -08:00
Bob Nystrom 088b1be98c Clean up config #defines. 2013-12-14 11:06:54 -08:00
Bob Nystrom 165cf29db0 Special "constructor methods" -> "new" instruction. 
This simplifies the call instruction a bit (and is overall
less code).
 2013-12-13 11:32:47 -08:00
Bob Nystrom d54bca3067 Get basic superclass method calls working. 2013-12-13 08:37:49 -08:00
Bob Nystrom 4957728893 Move OP_CLOSURE and OP_LIST down. 
Since they're less frequently used, pushing them down speeds
things up a little bit.
 2013-12-13 06:47:34 -08:00
Bob Nystrom 5aaaa33552 Revise benchmarks: 
- Ditch JS since it's in a different league.
- Make binary_trees and fib run faster.
- Compare using best time instead of mean.
 2013-12-12 16:59:57 -08:00
Bob Nystrom 8e71660ce6 Reorder the method types. 
Seems to slightly improve perf.
 2013-12-12 07:39:27 -08:00
Bob Nystrom 4ba5c38bbf Generate default constructors at compile time. 
Also re-ordered a few of the cases in the interpret loop. 
Removing a bit of code from CODE_CLASS and CODE_CALL triggered
some branch alignment issues which had a negative perf impact.
The new ordering seems to cancel that out.
 2013-12-12 07:34:16 -08:00
Bob Nystrom e191424a70 Make "super" a reserved word. 2013-12-11 08:02:17 -08:00

Bob Nystrom c1cfe1b9f6 Handle inherited fields correctly. 2013-12-10 16:13:25 -08:00
Bob Nystrom 1e2449893e Add baseline comparison to benchmark script. 
This way, I can track performance improvements and regressions.
 2013-12-07 22:15:25 -08:00
Bob Nystrom 42b04c6c90 Fix bug in loops. 
It was still popping the stack for the body even though loop
bodies are statements now.
 2013-12-07 18:47:40 -08:00
Bob Nystrom eb1e5b48d6 Fix up benchmarks and add method call one. 2013-12-07 18:43:39 -08:00

Bob Nystrom c91fcd12cc Treat ";" like newlines. 2013-12-04 19:12:21 -08:00
Bob Nystrom 8521d5ad79 Bunch more work on docs. 2013-12-04 07:46:41 -08:00
Bob Nystrom 047cfacede Include "include" directory in source code metrics. 2013-12-04 07:46:23 -08:00
Bob Nystrom 157944aa27 Get closures working! 
In the process, I had to change the grammar. There is now a strong
separation between statements and expressions. The code was just wrong
before when it popped locals at the end of a block scope because there
could be temporaries on the stack if the block was in expression
position. This fixes that.

Still need to implement closing over `this`.
 2013-12-04 07:43:50 -08:00
Bob Nystrom c14b115c02 Use char* instead of offsets for tokens. 
Simplifies a bunch of code that works with token strings.
 2013-12-01 15:22:24 -08:00
Bob Nystrom e4043d69b4 Unify code for ending compiler. 
There's now a single code path for the end of a chunk of bytecode, so
we can eventually put code there for capturing closures.
 2013-12-01 14:59:56 -08:00
Bob Nystrom 19811143a0 Always use provided allocator for allocation. 2013-12-01 10:22:32 -08:00

Bob Nystrom edb9032052 Get binary_trees benchmark working. 
Wren is actually doing well in it:

lua       mean: 3.5992 median: 3.6033 std_dev: 0.0156

Bob Nystrom f9b2aed4dd Unify to a single reallocation function. 2013-11-25 07:14:51 -08:00
Bob Nystrom ece3f3b83b Add optional support for computed gotos. 
In my benchmark, this gives like a 5% speed boost. But I'm not sure
it's taking full advantage of it. The XCode project is using LLVM,
which has support for it, but may not optimize it as much as GCC.

There are also some GCC flags I may need to set (-fno-gcse?) to get the
best perf on GCC. Needs more investigation.
