This is the first step towards pulling the DefineNamedOwn operation out
of StoreIC.
Summary of the renamed identifiers:
Bytecodes:
- StaNamedProperty -> SetNamedProperty: calls StoreIC and emitted for
normal named property sets like obj.x = 1.
- StaNamedOwnProperty -> DefineNamedOwnProperty: calls
DefineNamedOwnIC (previously StoreOwnIC), and emitted for
initialization of named properties in object literals and named
public class fields.
- StaKeyedProperty -> SetKeyedProperty: calls KeyedStoreIC and emitted
for keyed property sets like obj[x] = 1.
- StaKeyedPropertyAsDefine -> DefineKeyedOwnProperty: calls
DefineKeyedOwnIC (previously KeyedDefineOwnIC) and emitted for
initialization of private class fields and computed public class
fields.
- StaDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral: calls
DefineKeyedOwnPropertyInLiteral runtime function (previously
DefineDataPropertyInLiteral) and emitted for initialization of keyed
properties in object literals and static class initializers. (note
that previously the StoreDataPropertyInLiteral runtime function name
was taken by object spreads and array literal creation instead)
- LdaKeyedProperty -> GetKeyedProperty, LdaNamedProperty ->
GetNamedProperty, LdaNamedPropertyFromSuper ->
GetNamedPropertyFromSuper: we drop the Sta prefix for the property
store operations since the accumulator use is implicit and to make
the wording more natural, for symmetry the Lda prefix for the
property load operations is also dropped.
opcodes:
- (JS)StoreNamed -> (JS)SetNamedProperty: implements set semantics for
named properties, compiled from SetNamedProperty (previously
StaNamedProperty) and lowers to StoreIC or Runtime::kSetNamedProperty
- (JS)StoreNamedOwn -> (JS)DefineNamedOwnProperty: implements define
semantics for initializing named own properties in object literal and
public class fields, compiled from DefineNamedOwnProperty (previously
StaNamedOwnProperty) and lowers to DefineNamedOwnIC
(previously StoreOwnIC)
- (JS)StoreProperty -> (JS)SetKeyedProperty: implements set semantics
for keyed properties, only compiled from SetKeyedProperty(previously
StaKeyedProperty) and lowers to KeyedStoreIC
- (JS)DefineProperty -> (JS)DefineKeyedOwnProperty: implements define
semantics for initialization of private class fields and computed
public class fields, compiled from DefineKeyedOwnProperty (previously
StaKeyedPropertyAsDefine) and calls DefineKeyedOwnIC (previously
KeyedDefineOwnIC).
- (JS)StoreDataPropertyInLiteral ->
(JS)DefineKeyedOwnPropertyInLiteral: implements define semantics for
initialization of keyed properties in object literals and static
class initializers, compiled from DefineKeyedOwnPropertyInLiteral
(previously StaDataPropertyInLiteral) and calls the
DefineKeyedOwnPropertyInLiteral runtime function (previously
DefineDataPropertyInLiteral).
Runtime:
- DefineDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral:
following the bytecode/opcodes change, this is used by
DefineKeyedOwnPropertyInLiteral (previously StaDataPropertyInLiteral)
for object and class literal initialization.
- StoreDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral_Simple:
it's just a simplified version of DefineDataPropertyInLiteral that
does not update feedback or perform function name configuration.
This is used by object spread and array literal creation. Since we
are renaming DefineDataPropertyInLiteral to
DefineKeyedOwnPropertyInLiteral, rename this simplified version with
a `_Simple` suffix. We can consider merging it into
DefineKeyedOwnPropertyInLiteral in the future. See
https://docs.google.com/document/d/1jvSEvXFHRkxg4JX-j6ho3nRqAF8vZI2Ai7RI8AY54gM/edit?disco=AAAAQQIz6mU
- Other changes following the bytecode/IR changes
IC:
- StoreOwn -> DefineNamedOwn: used for initialization of named
properties in object literals and named public class fields.
- StoreOwnIC -> DefineNamedOwnIC
- StoreMode::kStoreOwn -> StoreMode::kDefineNamedOwn
- StoreICMode::kStoreOwn -> StoreICMode::kDefineNamedOwn
- IsStoreOwn() -> IsDefineNamedOwn()
- DefineOwn -> DefineKeyedOwn: IsDefineOwnIC() was already just
IsDefineKeyedOwnIC(), and IsAnyDefineOwn() includes both named and
keyed defines so we don't need an extra generic predicate.
- StoreMode::kDefineOwn -> StoreMode::kDefineKeyedOwn
- StoreICMode::kDefineOwn -> StoreICMode::kDefineKeyedOwn
- IsDefineOwn() -> IsDefineKeyedOwn()
- IsDefineOwnIC() -> IsDefineKeyedOwnIC()
- Removing IsKeyedDefineOwnIC() as its now a duplicate of
IsDefineKeyedOwnIC()
- KeyedDefineOwnIC -> DefineKeyedOwnIC,
KeyedDefineOwnGenericGenerator() -> DefineKeyedOwnGenericGenerator:
make the ordering of terms more consistent
- IsAnyStoreOwn() -> IsAnyDefineOwn(): this includes the renamed and
DefineNamedOwn and DefineKeyedOwn. Also is_any_store_own() is
removed since it's just a duplicate of this.
- IsKeyedStoreOwn() -> IsDefineNamedOwn(): it's unclear where the
"keyed" part came from, but it's only used when DefineNamedOwnIC
(previously StoreOwnIC) reuses KeyedStoreIC, so rename it accordingly
Interpreter & compiler:
- BytecodeArrayBuilder: following bytecode changes
- StoreNamedProperty -> SetNamedProperty
- StoreNamedOwnProperty -> DefineNamedOwnProperty
- StoreKeyedProperty -> SetKeyedProperty
- DefineKeyedProperty -> DefineKeyedOwnProperty
- StoreDataPropertyInLiteral -> DefineKeyedOwnPropertyInLiteral
- FeedbackSlotKind:
- kDefineOwnKeyed -> kDefineKeyedOwn: make the ordering of terms more
consistent
- kStoreOwnNamed -> kDefineNamedOwn: following the IC change
- kStoreNamed{Sloppy|Strict} -> kSetNamed{Sloppy|Strict}: only
used in StoreIC for set semantics
- kStoreKeyed{Sloppy|Strict} -> kSetKeyed{Sloppy|Strict}: only used
in KeyedStoreIC for set semantics
- kStoreDataPropertyInLiteral -> kDefineKeyedOwnPropertyInLiteral:
following the IC change
- BytecodeGraphBuilder
- StoreMode::kNormal, kOwn -> NamedStoreMode::kSet, kDefineOwn: this
is only used by BytecodeGraphBuilder::BuildNamedStore() to tell the
difference between SetNamedProperty and DefineNamedOwnProperty
operations.
Not changed:
- StoreIC and KeyedStoreIC currently contain mixed logic for both Set
and Define operations, and the paths are controlled by feedback. The
plan is to refactor the hierarchy like this:
```
- StoreIC
- DefineNamedOwnIC
- SetNamedIC (there could also be a NamedStoreIC if that's helpful)
- KeyedStoreIC
- SetKeyedIC
- DefineKeyedOwnIC
- DefineKeyedOwnICLiteral (could be merged into DefineKeyedOwnIC)
- StoreInArrayLiteralIC
- ...
```
StoreIC and KeyedStoreIC would then contain helpers shared by their
subclasses, therefore it still makes sense to keep the word "Store"
in their names since they would be generic base classes for both set
and define operations.
- The Lda and Sta prefixes of bytecodes not involving object properties
(e.g. Ldar, Star, LdaZero) are kept, since this patch focuses on
property operations, and distinction between Set and Define might be
less relevant or nonexistent for bytecodes not involving object
properties. We could consider rename some of them in future patches
if that's helpful though.

It's confusing that we have CSA_CHECK and CSA_ASSERT and it's not
clear from the names that the former works in release mode and the
latter only in debug mode.
Renaming CSA_ASSERT to CSA_DCHECK makes it clear what it does. So now
we have CSA_CHECK and CSA_DCHECK and they're not confusing.
This also renames assert() in Torque to dcheck().

We run tests in parallel which can cause multiple tests to write to
the shared v8.log file. This obviously breaks the simple assertions in
mjsunit/tools/log.js.
- Use temporary files for log testing with --logfile='+'
- Change the symbol from '&' to '+' for using temporary files for
logging with --logfile
- Enable skipped log tests again.

The new helper function allows us to write tests for log parsing
without the need of first generating a log file.
This makes it easier guard against errors when the log format changes.
- add d8.log.getAndStop helper
- add basic log test
- fix test that regresses due to changed gc timing

A new realm doesn't contain the mocks and suppressions on the global
object for correctness fuzzing. We replace Realm.eval with eval to
keep exercising the code.
