Once the GRWL is added, will also be for GC safepoints.

We always want to crawl the entire stack, and it's possible to determine the extents of the stack, so just do a scan over the entire memory range. Also, change the way the interpreter keeps track of its roots; we don't really need to associate the roots with a specific interpreter frame. This should hopefully clear up the weirdness about libunwind trying to unwind through the pthreads assembly code, and potentially also make stack crawling faster.

I think threading now "works" ie doesn't crash Pyston, though we don't release the GIL until the thread exits.

Don't worry, a non-gil version is coming. Use a gil for now so we can start working on the other threading requirements, such as GC.

Well, the thread-creating should work, but nothing is threadsafe.

Not all exposed to python code yet This commit is pretty large because it contains two separate but interrelated changes: - Rewrite the function argument handling code (callCompiledFunction and resolveCLFunc) into a single callFunc that does its own rewriting, and support the new features. -- this required a change of data representations, so instead of having each function consist of variants with unrelated signatures, we can only have a single signature, but multiple type specializations of that signature - To do that, had to rewrite all of the stdlib functions that used signature-variation (ex range1 + range2 + range3) to be a single function that took default arguments, and then took action appropriately.

Can emit add/sub/etc instructions with 32-bit operands in addition to 8-bit now Can get the RSP and RBP in rewriter1, for accessing scratch space Change some debugging output Fix a gc bug: if an object gets new'd, and takes a parameter that gets new'd, the sequence is 1) object space gets allocated 2) parameter space gets allocated 3) parameter gets constructed 4) object gets constructed The bug is that the object construction is what initializes the GC header, so if step #3 causes a collection, it can see that the allocation from step #1 has an invalid header. As a workaround, always zero out the header in allocation, and skip blocks with zeroed headers. The real solution is probably to have the GC manage the header itself rather than expecting the user to; this would mean that gc_alloc would take the allocation kind, put that into the header, and then return a pointer to the post-header data section of the allocation.

Currently many places in the codebase create AST_Jump objects but do not initalice the line ,col numbers. Set them to -1, in order to not call SetCurrentDebugLocation with random locations.

Replace a simple "num_args" argument with a packed struct that takes num_args and adds num_keywords, has_varargs, and has_kwargs. Tried to add asserts in all the places that don't allow keywords/varargs/starargs Started refactoring things; got to the point of attempting argument->parameter shuffling, but it's tricky if we allow every compilation to have a different signature (used by builtins). Really they all have the same signatures but different specializations; to get to that point, need to add defaults.

- Added dir0 which would in theory return the local scope, but for just returns the content of the builtins module - Added a unit test file for dir which won't print anything as the list sorting does not work as expected at the moment (missing full implementation) and the attributes are different as well (pyston has some CPython 2.7.5 does not have and vice versa) - dir1 implements the lookup on a passed object - If the object has a __dir__ method, it will call it and return the result returned by this method - Otherwise all class and instance attributes and methods are returned - If the object has a __dict__ attribute, additional to the previous one it will return the keys from that one as well Signed-off-by: Vinzenz Feenstra <evilissimo@gmail.com>
