vroundps assembly is incorrect: - the signature was wrong, vroundps takes 2 operands and 1 immediate - when calling vinstr, should always pass xmm0, this wasn't causing issues because our test cases were restricted enough that it was always xmm0 anyway - the macro assembler should use AVX_OP_SSE4_1, since roundps requires SSE4_1 - drive-by fix for roundss and roundsd to be AVX_OP_SSE4_1 - add disasm for roundps and vroundps, and test them Bug: v8:10553 Change-Id: I4046eb81a9f18d5af7137bbd46bfa0478e5a9ab2 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2227252Reviewed-by:

This CL repurposes the v8.wasm trace event category, and introduces additionally the v8.wasm.detailed category. The v8.wasm category is enabled by default and captures core wasm events like validation, compilation, instantiation, and important operations like grow-memory and tier-up timings. The v8.wasm.detailed category is disabled by default. It captures all events the previous v8.wasm category captured, like compilation of single functions, time needed for register allocation, ... This CL splits these categories to allow enabling the v8.wasm category in telemetry benchmarks to calculate compile time and other metrics from traces of telemetry runs.

This ports HeapStatsCollector (former ThreadHeapStatsCollector) from Blink. The CL only ports accounting of allocated object size which is needed for a simple growing strategy in a follow up. HeapStatsCollector is a global dependency for most sub components as it provides infrastructure for measuring time (through trace scopes) and space. The general idea of HeapStatsCollector is to act as sink where all sub components push time and space information. This information is then gathered and made available via an event that is implemented as POD. Time-dependent info is available through regular getters (pull) and observers (push).

When tiering down (or up), we first get a list of all native modules (under a lock), then tier them down/up without holding the lock. Since we don't hold (shared) ownership of the native module, it could die in-between. This CL fixes this by keeping weak pointers to the native modules, and re-gaining a shared pointer before putting the module in the list of modules to be tiered down/up.

This is a followup of the cl [1] that fixes a bug where bytecode was getting flushed when allocating feedback vector. The fix added IsCompiledScope before allocating a new feedback vector. We now pass IsCompiledScope to JSFunction::EnsureFeedbackVector. This makes it explicit that EnsureFeedbackVector expects a function that is compiled and the bytecode shouldn't be flushed during the allocation.Also adds a test.

This changes ReadOnlySpace to no longer be a PagedSpace but instead it is now a BaseSpace. BasicSpace is a new base class that Space inherits from and which has no allocation methods and does not dictate how the pages should be held. ReadOnlySpace unlike Space holds its pages as a std::vector<ReadOnlyPage>, where ReadOnlyPage directly subclasses BasicMemoryChunk, meaning they do not have prev_ and next_ pointers and cannot be held in a heap::List. This is desirable since with pointer compression we would like to remap these pages to different memory addresses which would be impossible with a heap::List. Since ReadOnlySpace no longer uses most of the code from the other Spaces it makes sense to simplify its memory allocation to use a simple bump pointer and always allocate a new page whenever an allocation exceeds the remaining space on the final page.

On x86-64, we spend significant time constructing and copying operands in Liftoff (around 5% locally). Inlining the constructor and helper functions removes most of the overhead.

https://crrev.com/c/2072858 rewrote the implementation of non-unicode ignore-case matches to comply with the JS spec in some corner cases. It fixed character matches and character class matches. We missed a similar bug in the implementation of back references. This CL fixes that bug. The main change is in regexp-macro-assembler.cc, where CaseInsensitiveCompareUC16 is split into CaseInsensitiveCompareUnicode (which has the same semantics as before) and CaseInsensitiveCompareNonUnicode (which has the semantics described here: https://tc39.es/ecma262/#sec-runtime-semantics-canonicalize-ch). Most of the rest of the patch undoes https://crrev.com/c/2081816 to once again make the unicode flag available to the macroassembler, so that we can decide which helper function to call. The testcase is a version of test/intl/regress-10248.js, modified to test backreferences.

This CL makes the test stricter by requiring specific string shapes; before it was possible to skip verification if strings were short-circuited, which I believe is no longer possible due to thin strings. I also added a regression test for the linked bug, which requires a String.p.split call on a two-byte-in-one-byte string with an empty string separator argument.
