Andreas Kling	7b863330dc	LibJS: Cache commonly used FlyStrings in the VM ... Roughly 7% of test-js runtime was spent creating FlyStrings from string literals. This patch frontloads that work and caches all the commonly used names in LibJS on a CommonPropertyNames struct that hangs off VM.	2020-10-13 23:57:45 +02:00
Andreas Kling	2bc5bc64fb	LibJS: Remove a whole bunch of includes of <LibJS/Interpreter.h>	2020-09-27 20:26:58 +02:00
Andreas Kling	6861c619c6	LibJS: Move most of Interpreter into VM ... This patch moves the exception state, call stack and scope stack from Interpreter to VM. I'm doing this to help myself discover what the split between Interpreter and VM should be, by shuffling things around and seeing what falls where. With these changes, we no longer have a persistent lexical environment for the current global object on the Interpreter's call stack. Instead, we push/pop that environment on Interpreter::run() enter/exit. Since it should only be used to find the global "this", and not for variable storage (that goes directly into the global object instead!), I had to insert some short-circuiting when walking the environment parent chain during variable lookup. Note that this is a "stepping stone" commit, not a final design.	2020-09-27 20:26:58 +02:00

Linus Groh	4f6912c605	LibJS: Store basic traceback in Exception ... Nothing fancy like line numbers, but Exception now stores a list of function names up to the current call frame.	2020-06-02 15:22:34 +02:00
Andreas Kling	faddf3a1db	LibJS: Implement "throw" ... You can now throw an expression to the nearest catcher! :^) To support throwing arbitrary values, I added an Exception class that sits as a wrapper around whatever is thrown. In the future it will be a logical place to store a call stack.	2020-03-24 22:21:58 +01:00
