A "store own" slow runtime was missing, and the slow handler on the StoreOwnIC was using the non-own slow runtime function, incorrectly causing setters to be called. For baseline, [1] invalidates the invariant that StoreOwnIC is only used for storing properties already in the literal boilerplate, since it's also used when the new literal is cloned from an object spread.

This prevents an overflow to happen in the heap snapshot generator. Furthermore it changes the relation of progress_counter_ and progress_total_ to always adhere to: * progress_counter_ <= progress_total_, * if: progress_counter_ == progress_total_, then it is done. With this change, if progress_counter_ happens to be bigger than progress_total_ (latter is an estimate), it will continue to report the same progress (<100%) until it is done. Before, it would repeatedly report 100% until it is done.

When evaluating a top-level expression while paused on a breakpoint, we don't support an await expression as top-level statement. In these cases, the error was not informative and could be improved. To do so, we now propagate the information from DebugEvaluate to ParseInfo and use the parse_info in parser-base to throw a more informative error while parsing.

Not all the SSE2 instructions can be extended to 256-bit wide AVX instructions, AVX only supports 128-bit wide packed integer operands, while AVX2 supports both 128-bit and 256-bit wide packed integer operands. Moreover, the 256-bit shift instructions use XMM register/m128 to store the shift count, while all the operands of others are YMM registers/m256 operands,so we have to divide the SSE2_INSTRUCTION_LIST into 3 lists, packed double, packed integer and packed integer shift.

Extend type assertions to all types covering JavaScript values. This is achieved by allocating type representations on the heap using newly defined HeapObject subclasses. To allocate these in the compiler, we disable concurrent compilation for the --assert-types flag for now. Fix two type errors that came up with the existing tests: 1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of OtherObject. 2. OperationTyper::NumberToString(Type) can type the result as the HeapConstant Factory::zero_string(). However, NumberToString does not always produce this string. To avoid regressions, the CL keeps the HeapConstant type and changes the runtime and builtin code to always produce the canonical "0" string. A few tests were failing because they check for truncations to work and prevent deoptimization. However, AssertType nodes destroy all truncations (which is by design), so these tests are incompatible and now disabled for the assert_types variant. Drive-by fix: a few minor Torque issues that came up. Change-Id: If03b7851f7e6803a2f69edead4fa91231998f764 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3234717Reviewed-by:

Recompute the spill offsets for values in the merge region, instead of reusing the offsets of the source. This ensures that spill slots stay contiguous (modulo alignment). This also solves a correctness issue where the spill offsets in the merge region could move up, thereby overwriting the source of another move. With this change, the spill offsets always move down (to fill the gap) or stay the same, such that processing them from bottom to top can only overwrite sources of already-processed moves. Since we do not reuse the current state's offsets, this might generate extra stack moves and regress generated code performance a bit. Drive-by: print spill offsets in the Liftoff trace R=clemensb@chromium.org Bug: v8:12270 Change-Id: I8d20df8fc1e80dd36b6f651de457686e9935a628 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3245115 Commit-Queue: Thibaud Michaud <thibaudm@chromium.org> Reviewed-by:

According to the spec, the three parameters (stdlib, foreign, and heap) must be mutually distinct. We did not check this yet, which led to observable differences between asm validation and standard JavaScript semantics.
