Since callgrind allows to control stats collection from the guest, this
allows us to reset the collection right before the benchmark starts.
This change exposes this to the benchmark runner and integrates
callgrind data parsing into bench.py, so that we can run bench.py with
--callgrind argument and, as long as the runner was built with callgrind
support, we get instruction counts from the run.
We convert instruction counts to seconds using 10G instructions/second
rate; there's no correct way to do this without simulating the full CPU
pipeline but it results in time units on a similar scale to real runs.
- Improve error recovery during type checking
- Initial (not fully complete) implementation for singleton types (RFC RFC: Singleton types #37)
- Implement a C-friendly interface for compiler (luacode.h)
- Remove C++ features from lua.h (removed default arguments from luau_load and lua_pushcfunction)
- Fix lua_breakpoint behavior when enabled=false
- Implement coroutine.close (RFC RFC: coroutine.close #88)
Note, this introduces small breaking changes in lua.h:
- luau_load env argument is now required, pass an extra 0
- lua_pushcfunction now must be called with 3 arguments; if you were calling it with 2 arguments, pass an extra NULL; if you were calling it with 4, use lua_pushcclosure.
These changes are necessary to make sure lua.h can be used from pure C - the future release will make it possible by adding an option to luaconf.h to change function name mangling to be C-compatible. We don't anticipate breaking the FFI interface in the future, but this change was necessary to restore C compatibility.
