5b87d26027 LibJIT+LibJS: Move JIT::Assembler into a new LibJIT library 
This will allow other parts of the system to generate machine code
at runtime. :^)

bfb527e614 LibJS/JIT: Call throw_if_needed_for_call() in cxx_call() 
This allows test-js to run to completion (although we do still have
some bugs to track down.)

72c31fdd01 LibJS: Remove all interactions between Assembler and BasicBlock 
With this change, Assembler is now free from LibJS concepts and could
move out to its own apartment. :^)

022974a43a LibJS/JIT: Let Compiler keep per-BasicBlock state internally 
Compiler now has a BasicBlockData struct for each BasicBlock. The struct
contains all the stuff that we previously stored with the
Bytecode::BasicBlock.

8a24d00b1a LibJS/JIT: Preserve the accumulator across PutByFoo 
This ensures that we don't clobber the accumulator when putting a value
to a setter.

1fb95c7df9 LibJS/JIT: Add fast path for LessThan Int32 < Int32 
This uses a new branch_if_both_int32() helper.

It's interesting to note that we can compare encoded Int32 values
without stripping the INT32_TAG, since it doesn't affect signedness
of values.

ea65214c57 LibJS/JIT: Add fast path for Increment with Int32 value 
This uses a new branch_if_int32() mechanism that takes a code generating
lambda whose code will run if the input register is an Int32 JS::Value.

e4c4fb09f9 LibJS/JIT: Add fast path for the ResolveThisBinding codegen 
We now generate a fast path for cached `this` values. The first time
`this` is resolved within a function, we call out to C++, but then
all subsequent accesses will hit the cache in Register::this_value().

0f735b3502 LibJS/JIT: Log both success and failure from the JIT compiler 
These logs will eventually go away, once the JIT compiler can always
compile everything. :^)

310bcd4717 LibJS/JIT: Don't keep trying to JIT unsupported bytecode executables 
We now only try jitting each Bytecode::Executable once, and then cache
the resulting NativeExecutable.

6a6ef6670c LibJS/JIT: Support the GetById bytecode op 
We can now do basic property (get) access in jitted code! :^)

8905682a16 LibJS/Bytecode: Begin moving shareable (JIT+Interpreter) stuff somewhere 
There are a lot of native C++ functions that will be used by both the
bytecode interpreter and jitted code. Let's put them in their own file
instead of having them in Interpreter.cpp.
 2023-10-27 19:07:22 +02:00
Andreas Kling
b923ca392d LibJS/JIT: Support all the binary bytecode ops :^) 
(And use the X macro to avoid repeating ourselves!)
 2023-10-27 19:07:22 +02:00
Andreas Kling
c2fe7af095 LibJS/JIT: Support the NewString bytecode op 
This necessitated making the JIT::Compiler aware of the current
Bytecode::Executable, since that's where all the string literals are
held, but that seems like a good thing.

Andreas Kling
9dd5be0186 LibJS/JIT: Compile the EnterUnwindContext and LeaveUnwindContext ops 
These push a "valid" unwind context on the stack and check_exception()
now knows how to jump to the (catch) handler if present.

(finally) finalizers will require some more work, but with this change,
we now have basic support for try...catch. :^)
 2023-10-27 19:07:22 +02:00
Andreas Kling
9d35016284 LibJS/JIT: Add Assembler::jump(Operand) and verify_not_reached() 
Yet another jump() overload, and also a way to crash if we end up
somewhere we shouldn't be while in jitted code.
 2023-10-27 19:07:22 +02:00
Andreas Kling
e3560c2545 LibJS/JIT: Propagate exceptions in the simplest case :^) 
We now establish a stack of "unwind contexts" similar to what the
bytecode interpreter does, but here, it's a stack of structs with
addresses to the catch and finally blocks.

Unwind contexts also have a "valid" flag, and the root unwind context
(always present, pushed on JIT code entry) has valid=false, which we
interpret in check_exception() as "return and let our caller deal with
the exception".

Anything in Compiler that may generate an exception should now also
call check_exception() ASAP to emit the code for handling this.
