The offset (also called "address") passed to the atomic builtins was 32-bit until now. With memory64, we will have to also accept 64-bit values there, or at least values within the allocatable memory range. This CL thus changes the builtins to receive uintptr values instead of uint32, and pass them on to the runtime functions as double (as before). The runtime then casts them back to uintptr_t instead of uint32_t. Liftoff is extended to zero-extend the uint32 value if needed. TurboFan already passed a machine-word sized integer before. Drive-by: Rename some "address" to "offset" to make the semantics more clear.

Originally, the Torque-generated verifier for a field with type Undefined|Zero|NonNullForeign would check `f.IsUndefined() || f.IsZero() || f.IsNonNullForeign()`. At some point, we changed Torque so that it now generates the much weaker `f.IsOddball() || f.IsSmi() || f.IsForeign()`. This change returns the verifiers to their initial precision. Mostly we can use the names of abstract types to build up the correct type check expression, but a few abstract types like PodArrayOfWasmValueType have no way that we can tell them apart from their parent type at runtime. It would be confusing to have a function Object::IsPodArrayOfWasmValueType which actually just checks whether the object is a ByteArray, so this change introduces a new annotation which allows abstract type declarations to state that they should use their parent type during verification. This change also adds new test cases to help avoid future regressions of this logic.

Implements https://github.com/tc39/ecma262/pull/2154, which allows module export names to be string literals. Semantics highlights: - It is a SyntaxError for string literal export names to have unpaired UTF16 surrogates. - It is a SyntaxError for string literal export names to be used as the local name without being followed by a 'from' clause. For example, `export { "foo" }` and `export { "foo" as "bar" }` are errors, but `export { "foo" } from "./module.js"` is allowed. The remaining failing test262 test is wrong: https://github.com/tc39/test262/issues/2866 Bug: v8:10964 Change-Id: Ib3e06e1ee6b3f1b60ed7f24e21902e17ddfc0351 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2482335 Commit-Queue: Shu-yu Guo <syg@chromium.org> Reviewed-by:

This CL enables basic optimizations in TurboFan for WebAssembly code, like dead code elimination (DeadCodeElimination), constant folding (MachineOperatorReducer), and control flow optimizations (CommonOperatorReducer). These optimizations were disabled originally to improve startup time, at the expense of slower generated code. However, with Liftoff as the baseline compiler, startup time is not so important anymore for TurboFan.

XMM registers/operands can be mixed with normal operands. We introduce 4 new enums to handle this case: - xmmreg, oper - oper, xmmreg - xmmreg, xmmoper - xmmoper, xmmreg The different between op and xmmop is what type of register to print if the modrm byte ends up decoding into a register. The only difference between the output of the DisasmX64 test is pinsrd, pinsrq, and pshuflw which had extras spaces. This is fixed with this patch.

Liftoff can currently run out of registers when compiling an atomic compare-exchange instruction. In order to see this crash, the following conditions must be met: - The offset in the instruction doesn't fit in a 12-bit immediate - Either FLAG_untrusted_code_mitigations is false, or trap handlers are enabled, so that AddMemoryMasking decides to do nothing The fix proposed in this CL is just to defer allocation of a temporary register until after CalculateActualAddress has finished, because it might have also needed a temporary register.

The previous limit was reached just before irregexp finished in sunspider/string-tagcloud and web-tooling-benchmark/coffeescript. This meant that we aborted execution and started over with a slower (but asymptotically faster) engine just before we would've finished, causing a performance regression.

There is a typo getting the values of the lanes, only on big-endian systems. (On little-endian systems, the use of LANE macro hides the error). Bug: v8:11008 Change-Id: I99efde506dab443efd336346ec920fcd957daae2 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2486614Reviewed-by:

This is similar to https://crrev.com/c/2466377, for all other checks for numeric_limits found in the same file. The check for float/double to uint32/uint64 doesn't seem to be replaceable, due to this check: https://source.chromium.org/chromium/chromium/src/+/master:v8/src/base/safe_conversions_impl.h;l=361;drc=c10c83c31ba0b774c3c05c73bb4894ba2495394b We probably need something specific for converting to float/doubles. I'll leave those as they are first.
