[JSC] Update adjusted thread numbers
https://bugs.webkit.org/show_bug.cgi?id=231696
Reviewed by Saam Barati.
This adjusted numbers were empirically obtained at that time.
But after that, we switched bmalloc to libpas in ARM64 macOS
so that we removed scalability bottleneck in concurrent compilers.
We evaluated and adjusted the configuration again.
It improves Speedometer2 by 0.9% and JetStream2 by 0.7%.

[JSC][32bit] Fix wrong branchAdd32 assembly for ARMv7
https://bugs.webkit.org/show_bug.cgi?id=231362
Reviewed by Yusuke Suzuki.
After the unlinked baseline jit was merged, a new branchAdd32 method
needed to be implemented for ARMv7, however, the first version
submitted by me used the add32 method to perform the add before
branching.
In this patch, we fix the call to add32 by adding a new private method
add32Impl with an optional parameter that selects either add or adds,
make branchAdd32 call the adds version.

Fix spec-correctness when inlining __proto__ intrinsic using get_by_id_with_this

My original fix in r283512 has some theoretical spec correctness issues.
I'm not sure if they can be materialized or not since we only use
get_by_id_with_this in very limited scenarios. However, this patch just
makes it so we call the getter instead of attempting to inline it
when using get_by_id_with_this.

Remove ImplicitAddress
https://bugs.webkit.org/show_bug.cgi?id=230820
<rdar://problem/83826318>
Reviewed by Yusuke Suzuki.
Because we rely on implicit conversion from RegisterID to int values,
some compilers (aka MSVC) might convert a constant RegisterID that's passed in
to nullptr instead of calling the implicit constructor in ImplicitAddress.
For example, I got bit by this when I had code that did:
loadPtr(regT0, xyz)
This called the loadPtr(void*, RegisterID) function with nullptr passed as
the first argument instead of the loadPtr(ImplicitAddress, RegisterID)
function.
Let's avoid any such problems in the future by just not using ImplicitAddress.

[JSC][ARMv7] Make LLInt CSR save/restore order match the JITs
https://bugs.webkit.org/show_bug.cgi?id=231517
Reviewed by Saam Barati.
Since the new unlinked baseline JIT was introduced, the baseline JIT
uses the metadata table GPR the same way as the LLInt does, and relies
on it being in a saved CSR in emit_op_catch. This unearthed an issue
in the order in which LLInt on ARMv7 stores and restores CSRs when
trying to handle exceptions. This patch fixes the mismatch.

Reviewed by Filip Pizlo.
This patch gives SourceID a proper type name and shrinks it to
32-bits on 64-bit systems. Shrinking the size makes room on
SourceProvider for metadata in a future patch I'm working on.
It's also pretty unlikely that any system has more than ~4 billion
script tags, evals, wasm modules so shinking the size is unlikely
to cause any debugger/profiling issues.

Reviewed by Yusuke Suzuki.
When I ported the phase to run right after bytecode parsing, I wanted
to maintain the same behavior as the prior pass that ran after CPS
rethreading. I noticed a slight bug in some of my logic that changed
some of heuristics and how they'd effect double voting.
The old patch was mimicking the "is loaded from" bit by using the NodeFlags.
Howver, this has some issues with how this interacts with our other uses
of NodeFlags. So, to make things simple, I just add a new "VariableIsUsed"
bit.

Implement the WebAssembly exception handling proposal
https://bugs.webkit.org/show_bug.cgi?id=229681
<rdar://81603387>
Reviewed by Keith Miller.
Add support for the WebAssembly exception handling proposal, as per
the WIP spec: https://github.com/WebAssembly/exception-handling
The proposal includes 6 new instructions: try, catch, catch_all,
delegate, throw and rethrow. All the instructions are supported by
the LLInt and B3 generators, but not yet supported in Air. Any
functions use exceptions will use B3 in BBQ.
A few important notes about the implementation:
- In B3, since we can now have multiple entrypoints (one for the
function entry + 1 for each catch/catch_all), we can no longer just
replace every value in the stack with a Phi when we find a new
entrypoint. This worked so far because of the assumption that any
block couldn't access its enclosing stack, and since the enclosing stack
would only be accessible when we exited the current block, we added Phis
at the end of each block when we had a new entrypoint. Now, since we have to capture all
live values at any point that might throw (calls, throw and rethrow),
we break that assumption. To simplify all the possible ways we might
have to merge the state from multiple entrypoints we now use B3
Variables to represent stack slots.
- Some extra information is required to be able to properly restore
the state when catching an exception:
- We added a field VM::calleeForWasmCatch. This field is necessary
because whenever we throw, we might end up in JavaScript, which
assumes the callee is a cell and uses it to get the VM and restore
callee saves. The issue is when catching exceptions in wasm we
still need the original callee, and if throwing and catching from
the same frame, that call frame slot has now been overwritten, so
we store its original value in the VM field.
- We also need to store the current Wasm Instance into the call
frame's slot for the `this` argument. The instance is used both by
the unwinder, to check if the exception being thrown matches the
exceptions handled by catch candidates, and by the catch implementation,
which is necessary when throwing from a cross instance call where both
the callee save or TLS will have the callee's instance.
- We store the current opcode for the llint, or the
call site index for B3, in the call frame slot for the argument
count tag. The call site index is used by the unwinder to check
if a given catch can handle the exception being thrown.

Because of the RegExp.prototype.compile API, we don't know if the RegExp

Run backwards propagation before we prune the graph after ForceOSRExit nodes in BytecodeParser
https://bugs.webkit.org/show_bug.cgi?id=230823
<rdar://problem/83565088>
Reviewed by Robin Morisset.
We've found yet another bug where pruning code after OSR exits
before running backwards propagation leads to us breaking the spec
in weird IR situations. In the particular test case here, we end
up not thinking we care about negative zero for an ArithNegate,
and we exit the program while recovering the value 0 instead of -0.
Fundamentally, backwards propagation wants to see all bytecode uses.
Therefore, it seems like a more sound strategy to run backwards propagation
before we end up mucking with the graph. This patch makes it so we run
backwards propagation inside bytecode parser before we prune the IR.
That way, the phase sees the graph as if it's an IR over the whole bytecode
graph.

Fix wrong edge type from get-by-val in 32 bits

After https://bugs.webkit.org/show_bug.cgi?id=230801, a different type

[JSC] JSPropertyNameEnumerator should not have cached prototype chain since empty JSPropertyNameEnumerator is shared
https://bugs.webkit.org/show_bug.cgi?id=231202
rdar://83815122
Reviewed by Keith Miller.
r282014 assumed an invariant that JSPropertyNameEnumerator's StructureChain is immutable.
This invariant is also used in validation of JSPropertyNameEnumerator. However, this
invariant was broken since we now have shared empty sentinel JSPropertyNameEnumerator, which can
be used for different structures having different prototype chain.
Since now we have shared JSPropertyNameEnumerator, JSPropertyNameEnumerator should not have
StructureChain in its member. When invalidating StructureChain in Structure, we also clear
cached JSPropertyNameEnumerator so that we do not get a stale JSPropertyNameEnumerator from
Structure even though watchpoint-based validation is not used.
This patch also removes ValidatedViaWatchpoint flag in JSPropertyNameEnumerator due to the same
reason. We should not modify JSPropertyNameEnumerator once it is instantiated. Instead, we encode
this flag as a lowest bit of m_cachedPropertyNameEnumerator. If it is validated via traversing (not watchpoints),
then this bit is set. So when loading that pointer from StructureRareData, we can quickly detect
it without even accessing to the enumerator. This fixes the issue, and it is even cleaner.
We rename m_cachedPropertyNameEnumerator to m_cachedPropertyNameEnumeratorAndFlag since it now
includes this flag.
While reviewing the code, we also found that watchpoint-based validation didn't care about PolyProto.
We should disable watchpoint-based validation if PolyProto is used.

Reviewed by Yusuke Suzuki.
The whole point of get_by_id_with_this is to have different

this. This patch makes the __proto__ intrinsic getter do the right
thing. For typed array intrinsic getters, if they have different
|this| value vs slot base, we chose not to inline them, because
the type checks are not on the |this| value, so they're not guaranteed
to be typed arrays. We can improve upon this in the future.

the OSR exit code will materialize registers as if A is LLInt.
- We tier up A to Baseline JIT code.
- Now, we take the exit to A as if it's LLInt. But the checkpoint OSR exit
code will actually jump to the tiered up baseline code when it's done,
because it determines where to jump at runtime. Because of this, when
we return from the checkpoint code, and if we are jumping into baseline
code, we must always load the constant pool register.
- There's no need to load the metadata register because that register is

The phase was searching backwards in the graph to see if it found the RegExp

We were incorrectly assuming it was "0" in a program like this:
a: JSConstant(RegExp)
b: RegExpExec(@a)
And we assumed we're invoking RegExpExec with lastIndex is 0, because we found
our RegExp in a backwards search. This is likely because we're also matching
NewRegExp nodes, in which case, it is valid to say lastIndex is 0.
This caused us to return a constant value that would've been the exec

Make byte codes with arithmetic profiles switch to using an index instead of a pointer in metadata

Reviewed by Yusuke Suzuki.
This patch makes each bytecode that uses a BinaryArithProfile/UnaryArithProfile
have an index into a table instead of storing a pointer to the profile in its metadata.
Then, we can just load the profile using the index in the bytecode, which saves memory.

Speed up setting JSFunction's "prototype" property
https://bugs.webkit.org/show_bug.cgi?id=230864
Reviewed by Yusuke Suzuki.
This patch:
1. Removes "prototype" lookup from put(), which was non-inlineable and created an
interim object with "constructor" field. Instead, the new value is put directly,
with correct attributes, and respecting an altered receiver. This results in 2.8X
perf boost for very common case of setting "prototype": `Cat.prototype = new Animal`.
2. Simplifies initialization of class constructor's prototype object, removing tentacles
from getOwnPropertySlot() and extracting constructPrototypeObject() helper. Provides
a fast path for op_define_data_property, speeding up `class` creation by ~40%, while
reifies normal function's prototype with correct attributes for Object.defineProperty().

[WTF] Add ApproximateTime
https://bugs.webkit.org/show_bug.cgi?id=230876
Reviewed by Filip Pizlo.
This patch adds ApproximateTime, which offers monotonically increasing time but with coarse-grained resolution.
ApproximateTime::now() is faster than normal MonotonicTime::now(), so that we can use this when we do not care
about high resolution. For example, in Darwin x64, it is ~4x faster.
Internally, it is using mach_approximate_time() in Darwin, clock_gettime+CLOCK_MONOTONIC_COARSE in Linux, and
clock_gettime+CLOCK_MONOTONIC_FAST in FreeBSD. On the other platforms, we simply use the same source to MonotonicTime.
wall-time-now 102.2614+-0.2449
approximate-time-now 23.2583+-0.4083
monotonic-time-now 88.8518+-2.4106
We would like to use it in some places in JavaScriptCore in a subsequent patch: CodeBlock's creation time, GC time etc.

Build an unlinked baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=229223
<rdar://problem/82321772>
Reviewed by Yusuke Suzuki.
This patch adds an "unlinked" baseline JIT to JSVALUE64 platforms. The JIT
code produced by this baseline JIT can be shared between all CodeBlocks that
share an UnlinkedCodeBlock. The benefit of this is, if we're creating a CodeBlock
from an UnlinkedCodeBlock that already compiled an unlinked baseline JIT
instance, this new CodeBlock just starts off executing in the baseline JIT
"for free".
To make this work, the code we emit now needs to be independent of a specific
CodeBlock instance. We use a CodeBlock instance for minimal profiling information
when compiling, but otherwise, the code is tied to the UnlinkedCodeBlock. When
we need CodeBlock specific information, we load it. This usually means things
like we'll load things from the Metadata dynamically. This patch also adds a
"linked constant pool" concept, and anytime we instantiate such a CodeBlock,
we also need to instantiate this "linked constant pool". This contains things
like our inline cache data structures (StructureStubInfo*), JSGlobalObject*,
etc.
Unlinked baseline JIT always runs ICs in the "data" mode. To make this work, I
made data ICs work on x86_64. To do this, we no longer call/ret to the IC.
Instead, we jump to the IC, and the IC jumps back by loading the "done" location
from the StructureStubInfo dynamically. This simplifies the design to not be
based on the arm64 calling convention, and keeps the same performance characteristics.
This patch also adds a new version of InlineAccess that is only used in baseline
JIT (for now). In the future, we can make the DFG/FTL also use this for Data
ICs. But we don't need to do that yet since those tiers don't use data ICs by
default. The baseline JIT now has a pure data IC approach to InlineAccess. So
instead of repatching code, we repatch fields we load dynamically.
This patch also cleans up a few things in OSR exit, where both DFG/FTL were
storing callee saves to the callee saves buffer in a weird place, and separate
from one another. I noticed this code can be simplified if we just store
callee saves at the end of the OSR exit handler, and from common JIT emission
code.
This patch also fixes a bug where we could end up with the wrong (and always
more negative) SP in the baseline JIT. This could happen when we OSR exit
from an inlined getter/setter. The OSR exit code puts the return PC when
returning to the call site of the getter/setter to be the inline cache's
"done location". However, this "done location" didn't used to restore SP.
This patch conservatively makes it so that we restore the SP at these sites.
This is measured as a 1% speedup on Speedometer2.

Build an unlinked baseline JIT
https://bugs.webkit.org/show_bug.cgi?id=229223
<rdar://problem/82321772>
Reviewed by Yusuke Suzuki.
This patch adds an "unlinked" baseline JIT to JSVALUE64 platforms. The JIT
code produced by this baseline JIT can be shared between all CodeBlocks that
share an UnlinkedCodeBlock. The benefit of this is, if we're creating a CodeBlock
from an UnlinkedCodeBlock that already compiled an unlinked baseline JIT
instance, this new CodeBlock just starts off executing in the baseline JIT
"for free".
To make this work, the code we emit now needs to be independent of a specific
CodeBlock instance. We use a CodeBlock instance for minimal profiling information
when compiling, but otherwise, the code is tied to the UnlinkedCodeBlock. When
we need CodeBlock specific information, we load it. This usually means things
like we'll load things from the Metadata dynamically. This patch also adds a
"linked constant pool" concept, and anytime we instantiate such a CodeBlock,
we also need to instantiate this "linked constant pool". This contains things
like our inline cache data structures (StructureStubInfo*), JSGlobalObject*,
etc.
Unlinked baseline JIT always runs ICs in the "data" mode. To make this work, I
made data ICs work on x86_64. To do this, we no longer call/ret to the IC.
Instead, we jump to the IC, and the IC jumps back by loading the "done" location
from the StructureStubInfo dynamically. This simplifies the design to not be
based on the arm64 calling convention, and keeps the same performance characteristics.
This patch also adds a new version of InlineAccess that is only used in baseline
JIT (for now). In the future, we can make the DFG/FTL also use this for Data
ICs. But we don't need to do that yet since those tiers don't use data ICs by
default. The baseline JIT now has a pure data IC approach to InlineAccess. So
instead of repatching code, we repatch fields we load dynamically.
This patch also cleans up a few things in OSR exit, where both DFG/FTL were
storing callee saves to the callee saves buffer in a weird place, and separate
from one another. I noticed this code can be simplified if we just store
callee saves at the end of the OSR exit handler, and from common JIT emission
code.
This patch also fixes a bug where we could end up with the wrong (and always
more negative) SP in the baseline JIT. This could happen when we OSR exit
from an inlined getter/setter. The OSR exit code puts the return PC when
returning to the call site of the getter/setter to be the inline cache's
"done location". However, this "done location" didn't used to restore SP.
This patch conservatively makes it so that we restore the SP at these sites.
This is measured as a 1% speedup on Speedometer2.
