According to the spec, in case where the property is non-configurable and non-writable, the value passed to the set trap should be compared to the data.

So far, calls to Wasm C/C++ API functions reused the call descriptors of WasmImportWrappers, and the stack frame type of regular Wasm functions. This CL cleans that up by introducing separate implementations for both. No change in functionality or performance is expected.

The proposal is changing accordingly, see https://github.com/WebAssembly/reference-types/issues/36. In our tests we were already using the new format implicitly, because bulk-memory-operations are enabled by default. I noticed the missing implementation when I executed spec tests with --no-experimental-wasm-bulk-memory.

The backtracking stack (which is actually a generic stack) used to be statically sized. At 10k elements, it was fairly large, but still easy to overflow on large subject strings. This CL changes it to a std::vector-based implementation instead which grows on-demand. Drive-by: Add braces to the BYTECODE cases to make clang-format produce a nicer output.

This removes two default switch cases for unsupported opcodes, and replaces them by explicit lists. This makes it easy to see what is currently not supported in Liftoff. In a follow-up CL, each bailout will be associated with a category to track which features currently cause Liftoff to bailout. This change also makes Liftoff crash (in UNREACHABLE) if invoked with asm.js code. Hence, change the asm.js tests to not test Liftoff. In production, we do not invoke Liftoff for asm.js anyway.

On Android libraries there are zero length entries within the ranged symbols which break our range processing. This updates the logic to only add entries for zero-length entries if they aren't within the range of the previously added entry.

On Android we load the native library directly from the APK. As such, we need to convert symbols from the mapped APK to the underlying .so when symbolizing the ticks. This CL adds a --apk-embedded-library argument to tick processor to enable specifying which unstripped library file was embeded in the APK and enable symbolizing.

If we need to build an icu::UnicodeString for a string that is currently in one-byte representation, we first have to expand the string's content into a two-byte representation. Doing so involves allocating an array, which is slow. With this change, we can convert short strings on the stack instead to save time. The cutoff length for what counts as "short" is pretty arbitrary, but we believe many strings fit into an 80-column line. This increases the score of cdjs in JetStream 2 by 35% on my machine, because cdjs is basically a test of localeCompare throughput.

In a new test suite: "wasm-api-tests", using a new binary "wasm_api_tests", powered by gtest/gmock (like unittests). Also fix a bunch of issues that these tests uncovered, mostly to ensure that the stack is walkable.

The DecompressionElimination reducer can handle that case with the comparison of Decompress vs HeapConstant. There is no need to do extra work. Reverts parts of https://chromium-review.googlesource.com/c/v8/v8/+/1518182. The rest of that CL was reverted in a previous CL where the AccessBuilders were updated.

We currently have three different compresses that we thought it could be a good idea to merge into only one. Merging them would make sense since they all end up with the same code being generated. However, we would be losing knowing the MachineRepresentation in the cases of CompressSigned and Pointer. For example, in machine-graph-verifier everything will have to be MachineRepresentation::kCompressed https://cs.chromium.org/chromium/src/v8/src/compiler/machine-graph-verifier.cc?l=226 Cq-Include-Trybots: luci.v8.try:v8_linux64_pointer_compression_rel_ng Cq-Include-Trybots: luci.v8.try:v8_linux64_arm64_pointer_compression_rel_ng Bug: v8:8977, v8:7703 Change-Id: I244e2e61cab2bb87830bc0aabdbe5e43f243b424 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1624798Reviewed-by: Michael Stanton <mvstanton@chromium.org> Commit-Queue: Santiago Aboy Solanes <solanes@chromium.org> Cr-Commit-Position: refs/heads/master@{#61882}
