3b239b64ff LibJS/JIT: Remove debug spam in cxx_increment() 2023-10-27 19:07:22 +02:00

e2f5bfb4c4 LibJS/JIT: Always mask everything but LSB in ToBoolean 
As it turns out, cxx_to_boolean() may return "bool" as other values
than just 0 or 1. This happens when the C++ compiler decides to only
update the AL portion of the RAX return value register instead of
the whole thing.

5b198ccf32 LibJS+LibJIT: Don't turn patchable movs into xors with self 
If a mov instruction is meant to be patchable, we don't want to rewrite
it as a xor, since that removes the slot where we'd patch in the right
value later.

Also, make sure to set both size bits in the REX prefix for xoring a
register with itself.

8b32e98f3f LibJS/JIT: Simplify Increment Int32 fast path 
When we know the value is a positive Int32 less than 0x7fffffff,
it's safe to just add 1 to it and use that as the final result.
This avoids the work of re-adding the INT32_TAG.

b43e38112c LibJS/JIT: Use JIT::Assembler::jump_if_zero() to improve code size 2023-10-27 19:07:22 +02:00

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().

310bcd4717 LibJS/JIT: Don't keep trying to JIT unsupported bytecode executables

the resulting NativeExecutable.

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.

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.
