This adds a new InstanceOfIC where the TestInstanceOf bytecode collects
constant feedback about the right-hand side of instanceof operators,
including both JSFunction and JSBoundFunction instances. TurboFan then
uses the feedback to optimize instanceof in places where the right-hand
side is not a known constant (known to TurboFan).
This addresses the odd performance cliff that we see with instanceof in
functions with multiple closures. It was discovered as one of the main
bottlenecks on the uglify-es test in the web-tooling-benchmark. The
uglify-es test (run in separation) is ~18% faster with this change.
On the micro-benchmark in the tracking bug we go from
instanceofSingleClosure_Const: 69 ms.
instanceofSingleClosure_Class: 246 ms.
instanceofMultiClosure: 246 ms.
instanceofParameter: 246 ms.
to
instanceofSingleClosure_Const: 70 ms.
instanceofSingleClosure_Class: 75 ms.
instanceofMultiClosure: 76 ms.
instanceofParameter: 73 ms.
boosting performance by roughly 3.6x and thus effectively removing the
performance cliff around instanceof.

There are wasm operations which operate on floats or double, but they
need to preserve the exact bit pattern. Thus they cannot be stored and
passed as float or double, since that might flip the signaling NaN bit.
This CL extends WasmValue to store floats and doubles as bit pattern,
and adds accessors to extract them as Float32 or Float64.
The interpreter is changed to execute certain operations (i32.abs,
i32.neg, i64.abs, i64.neg, f32.reinterpret/i32, f64.reinterpret/i64) on
boxed floats.

Implicitly escape all output that is passed to Log::MessageBuilder.
We escape non-printable characters and the log field separator ','
using the \x00 and \u0000 escape sequences.
Example:
Before: event-foo,"space: ","comma: ,","double quotes: """
After: event-foo,space: ,comma: \x2C,double quotes: "
This might slightly impact human readability of the log files in
extreme cases. However, most strings do not contain any escaped
characters.

with two results. Further details in the design doc:
https://docs.google.com/document/d/10foP3m7SDWyFfbda96iEJ_XYOLQdd32AeoP8SD1cTcs/edit#heading=h.bghdno28mr7u
- Allow to derive the MachineType from a static type.
This allows to select the right MachineType when performing a
load/store.
- Disallow casts (UncheckedCast() or CAST()) when the target and
origin type have no overlap.
New cast ReinterpretCast() is an UncheckedCast without this check.
- Caveat of this CL: Checked casts (CAST()) are not possible for
UnionType<T1,T2> with the exception of Number (due to the existence
of Number in OBJECT_TYPE_LIST and the existence of an IsNumber()
function in the runtime).

Moves the feedback vector slot allocation out of ast-numbering and into
bytecode generation directly. This has a couple of benifits, including reduced
AST size, avoid code duplication and reduced feedback vector sizes in many cases
due to only allocating slots when needed. Also removes AstProperties since
this is no longer needed.
AstNumbering is now only used to allocate suspend ids for generators.

The DoubleToI stub is no longer called outside of TurboFan, and always in the
same way:
- The parameter is on top of the stack.
- The stub is always called in a slow path.
- It truncates.
Therefore, we can simplify it to only support this case and remove dead
code.
On top of this, since the stub is always considered to be on a slow path for all
backends, this patch takes the opportunity to remove the `skip_fastpath`
optimisation. This would generate a stub which does not handle all inputs,
assuming that the backend already handled some of the inputs in a fast
path. Removing this allows the stub to have the same behaviour on all targets.
On Arm, this patch reworks the stub a little. We could use ip instead of saving
and restoring a register on the stack. Also, comments would mention that we
assume the exponent to be greater than 31 when the it can be 30 or higher. As
done for Arm64, let's check this at runtime in debug mode.
On Arm64, we can also implement the stub without pushing and poping off the
stack. It needs 2 general purpose and a double scratch registers which we have
reserved already (ip0, ip1 and d30). This removes the need to check that the
stack pointer is always 16-bytes aligned.
Finally, this also fixes a potential bug on Arm64, in the
`GetAllocatableRegisterThatIsNotOneOf` method which is now removed. We were
picking an allocatable double register when we meant to pick a general one.

Inner functions which called eval, and were the kind of functions
that can use `super`, were erroneously not marked as "uses_super_property",
leading to downstream crashes when the runtime tried to load the
[[HomeObject]] from them.
This patch eliminates the public Scope::uses_super_property()
API and ensures that callers always call Scope::NeedsHomeObject()
instead.
This is a minimal fix designed for easy merging; it's likely that
in the long run we should remove most mentions of "uses super property"
and replace them with "needs home object" for clarity.

When an immediate does not fit an add instruction we use a temporary register to
hold the value, using movw/movt to encode it. However, in order to remove a use
of r9 in TurboFan's code generator, we need to cope with no scratch registers
being available. That is to say that the destination and source registers are
the same, and `ip` is not available to use.
In this case, we can split an add instruction into a sequence of additions:
```
UseScratchRegisterScope temps(...);
Register my_scratch = temps.Acquire();
__ add(r0, r0, Operand(0xabcd); // add r0, r0, #0xcd
// add r0, r0, #0xab00
```
As a drive-by fix, make the disassembler test fail if we expected a different
number of instructions generated.

In the current implementation of hash code for objects (identity hash),
we do not bother to shift the hash when we retrieve it from the
hash-length bitfield in a property array. (Even worse, we store shifted
value even if we do not have property array or inside dictionaries.)
That means that the hash-code for objects is always divisible by 1024.
Since our hash table uses a simple masking with (2^logsize - 1) to
obtain the bucket, we get terrible hash collisions - essentially, our
hash table degenerates to a linked list for fewer than 1024 elements.
This CL always shifts the hash code so that the value in the lowest
21 bits is uniformly distributed.
This results in big improvements on medium to large hash tables.
A program storing 1M elements into a WeakMap gets roughly
17x faster. A program retrieving 1M elements from a Map
improves even more dramatically (>100x).
const a = [];
for (let i = 0; i < 1e6; i++) a[i] = {};
const m = new Map();
console.time("Map.set");
for (let i = 0; i < 1e6; i++) {
m.set(a[i], i);
}
console.timeEnd("Map.set");
console.time("Map.get");
let s = 0;
for (let i = 0; i < 1e6; i++) {
s += m.get(a[i]);
}
console.timeEnd("Map.get");
const w = new WeakMap();
console.time("WeakMap.set");
for (let i = 0; i < 1e6; i++) {
w.set(a[i], i);
}
console.timeEnd("WeakMap.set");
Before the fix:
Map.set: 157.575000
Map.get: 28333.182000
WeakMap.set: 6923.826000
After the fix:
Map.set: 178.382000
Map.get: 185.930000
WeakMap.set: 409.529000
Note that Map does not suffer from the hash collision on insertion because
it uses chaining (insertion into linked list is fast regardless of size!), and
we cleverly avoid lookup in the hash table on update if the key does not have
identity hash yet. This is in contrast to the WeakMap, which uses
open-addressing, and deals with collisions on insertion.

This patch is a first step towards target independent tests for the
CodeGenerator's AssembleMove and AssembleSwap methods.
The tests on top of which this builds would only make sure that no assertions
were triggered while generating moves, and that the hardware is happy executing
them. We want to do more and check that the generated code performs correctly.
In a nutshell, this introduces a facility that can do the following:
- Setup an environment with registers and stack slots initialised with random
values.
- Perform a list of randomly generated moves and/or swaps on those.
- Return the resulting environment.
This is a first step and therefore is lacking a few things which will be
implemented as follow-ups:
- Support for kSimd128 moves and swaps.
- Support large offsets for stack moves, as well as positive and negative.
- Compare the resulting environment against the result of a reference
simulation.

When starting profiling, we iterate the heap to find all existing code
objects and the associated functions.
The iteration tried to log the function's code if either the closure's
code was optimized-but-not-deoptimized or if the optimized code in its
feedback vector was optimized-but-not-deoptimized.
That caused some trouble if the function's code was deoptimized but
we had a valid optimized code in the feedback vector. In that case
we would log the deoptimized code object from the closure, which
would later crash when trying to access the deoptimization information
(which we clear on deoptimization).
This CL just fixes the iteration so that we do not crash. A better fix
might be to log the function's code object if not deoptimized *and*
the code object in type feedback vector if not not deoptimized. Or
perhaps iterate optimized code objects and log those that have
deoptimization information.

This flag was originally added as a staging mechanism to let us land and test
guard regions without the full trap handler feature landing. Additionally, we
thought we might enable guard regions without trap handlers on some systems.
Trap handlers are now supported, and there's not a real compelling reason for
why we need guard regions without trap handlers. Keeping the separate flag leads
to confusion, since some code treats guard regions and trap handlers the same,
while other code treats them as independent.
Removing this flag and its associated special cases makes everything more
uniform and predictable.

The catch variable is a special VAR-mode variable which is not in a declaration
scope. Normally creating such a variable is not possible with DeclareVariable,
but Parser bypasses it by calling DeclareLocal directly (which doesn't have the
hoisting check).
PreParser used to cut corners and declare the catch variable as a LET-mode
variable to prevent hoisting.
But since LET and VAR variables behave differently when deciding whether they
block sloppy block function hoisting, that approach doesn't fly.

Sometimes, the embedder might want to merge a fix to an abandoned branch
or to a supported branch but the fix is not relevant to Chromium.
This adds a new version string that the embedder can set at compile time
and that will be appended to the official V8 version.
The separator must be provided in the string. For instance, to have a
full version string like "6.0.287.53-emb.1", the embedder must set
V8_EMBEDDER_STRING to "-emb.1".

proposal, which just changes how these characters are handled in

would be wonderful if we could get away with it, but no one really has
any data on whether or not we could. Adding this use counter lets us get

The WasmContext struct introduced in this CL is used to store the
mem_size and mem_start address of the wasm memory. These variables can
be accessed at C++ level at graph build time (e.g., initialized during
instance building). When the GrowMemory runtime is invoked, the context
variables can be changed in the WasmContext at C++ level so that the
generated code will load the correct values.
This requires to insert a relocatable pointer only in the
JSToWasmWrapper (and in the other wasm entry points), the value is then
passed from function to function as an automatically added additional
parameter. The WasmContext is then dropped when creating an Interpreter
Entry or when invoking a JavaScript function. This removes the need of
patching the generated code at runtime (i.e., when the memory grows)
with respect to WASM_MEMORY_REFERENCE and WASM_MEMORY_SIZE_REFERENCE.
However, we still need to patch the code at instance build time to patch
the JSToWasmWrappers; in fact the address of the WasmContext is not
known during compilation, but only when the instance is built.
The WasmContext address is passed as the first parameter. This has the
advantage of not having to move the WasmContext around if the function
does not use many registers. This CL also changes the wasm calling
convention so that the first parameter register is different from the
return value register. The WasmContext is attached to every
WasmMemoryObject, to share the same context with multiple instances
sharing the same memory. Moreover, the nodes representing the
WasmContext variables are cached in the SSA environment, similarly to
other local variables that might change during execution. The nodes are
created when initializing the SSA environment and refreshed every time a
grow_memory or a function call happens, so that we are sure that they
always represent the correct mem_size and mem_start variables.
This CL also removes the WasmMemorySize runtime (since it's now possible
to directly retrieve mem_size from the context) and simplifies the
GrowMemory runtime (since every instance now has a memory_object).

Note that this also makes it possible to move several classes
into the module-compiler.cc file and inline their implementations.
This also allows removing several uses of wasm-module.h from
other places in V8 that include wasm-objects.h.

There are only very few custom compiled IC handlers left that go in there, and for each compiled handler we only have 1 cache hit on top25; maximally saving 60ms over 33s. Additionally we'll migrate the remaining handlers to data-driven handlers anyway. Let's try to remove this code.

ZoneList still used List as a base class, so this CL merges the two
classes together. We also remove unused functions in List and ZoneList.
We keep the inline header but move it to src/zone/zone-list-inl.h. The
includes that use this header are still quite tangled, but we can fix
that later.

This CL teaches the respective bytecode handlers and standalone stubs
about BigInts, and collects "kBigInt" feedback for them. However,
Turbofan does not yet care about such feedback, so it is simply converted
to "any" for now (making TF emit stub calls for BigInt operations).

In the test-run-wasm and test-run-wasm-64 cctests it is not possible to
call runtime functions. To test traps in these cctests we therefore
replace the runtime call with a call to a c-callback, followed by a
return. This CL fixes the problem that the return did not clean up stack
parameters.
This CL unblocks
https://chromium-review.googlesource.com/c/v8/v8/+/671008. Originally I
wanted to mitigate the problem in that CL by defining an additional
parameter register for arm. However, adding additional parameter
registers lets other tests fail.
