The `Debugger.getScriptSource()` and `Debugger.getWasmBytecode()` methods in the CDP return Wasm wire bytes as protocol::Binary, which is send as Base64-encoded JSON string in the communication to the DevTools front-end, and hence leads to either crashing the renderer that is being debugged or the renderer that's running the front-end if we allow arbitrarily huge Wasm byte sequences here. This CL introduces a limit, based on the maximum allowed string length, to avoid the crash and instead signal a proper error to the DevTools front-end.

Motivation: The immediate-argument classes defined in function-body-decoder.h were often adding an offset to the provided pc. This was inconsistent, bug-prone, and counterintuitive. This CL imposes that all immediates are passed as pc the start of the immediate argument they are parsing. Some other smaller inconsistencies are fixed as well. Changes: src/wasm/: - Enforce that all Immediates are passed the pc at the start of the argument they are parsing. Adapt all call sites. - Remove unneeded offset arguments from two SIMD related immediates. - Add a pc argument to all Validate functions for immediates instead of using the Decoder's current pc. - Remove the (unused) pc argument from all Complete functions for immediates. - Introduce Validate() for BranchOnExceptionImmediate. - In WasmDecoder::Decode(), make sure len is updated before breaking out of the loop in case of a Validate() failure. - Change the default prefix_len of DecodeLoadMem/DecodeStoreMem to 1. wasm-interpreter.cc: - Change the default prefix_len of ExecuteLoad/Store to 1. - Adapt offsets in calls to Immediates. - Remove redundant opcode_length argument from ExecuteSimdOp, use len in its place. function-body-decoder-unittest.cc - Adapt offsets in calls to Immediates. - Introduce and use EXPECT_OK, as is done in other tests.

It turns out that Liftoff often needs to know the size of a value in bytes. Currently we are loading the size_log_2 from an array and then performing a shift by that amount. We can slightly speed this up by just loading the correct value directly. Drive-by: Use {int8_t} for the internal array, since all values will easily fit in that range.

Each single branch in the switch was push a new value on the operand stack, but the code for that was not shared. This CL refactors this such that we only allocate once, and then modify the new slot as needed. This makes the generated code a lot smaller (771 bytes instead of 1052 bytes on x64), and hopefully also faster.

Prototype f64x2.ceil on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintp, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintp, which is the same instruction used for Float64RoundUp (scalar), wasm-compiler reuses the Float64RoundUp check.

The current code for AssignRegisterOnReload starts the search at the first interval instead of relying on the cached {current_interval_}, which seems to be a main cause for slow compile time in the linked issue's test case. Moreover, it does not take into account live range holes of the current range. This change uses FirstIntersection instead which already handles both issues. Since inactive ranges are sorted by their next start, we can also break early from the loop.

Bitmask requires wasm_simd_post_mvp because it was merged into SIMD proposal after 84 cut, which Origin Trial starts. For now, bitmask is the only instruction that requires this flag to be set, and no other post mvp instructions are included in the fuzzer. We should revert this change (and also move bitmask out of the flag) after this OT is over.

This retrieves script name directly from StackFrameBase, bypassing building of StackFrameInfo if one hasn't already been initialized, thus avoiding computation of expensive properties that are not required. This matches current behavior of GetScriptNameOrSourceURL() and is a workaround until a dedicated API is available.

Local type information was stored in the {WasmFullDecoder}, and a pointer to that vector was handed to {WasmDecoder}. Since {WasmFullDecoder} inherits from {WasmDecoder}, we can just move the vector to the {WasmDecoder} class, and save an indirection and an unnecessary nullptr check. Drive-by: Rename {GetLocalType} to {local_type}, since it's a simple accessor. Drive-by 2: Move fields of {WasmDecoder} to the end of the class, as mandated in the style guide. Drive-by 3: Rename some locals in the 'let' decoding to make the meaning more clear.

Currently the FeedbackVector uses arrays in slots that are polymorphic, usually in a <map, handler> tuple pattern. Helper functions try to re-use an existing array if it's already in place. For Concurrent TurboFan, it would be far better if these FixedArrays were immutable. We could then count on semantic correctness when harvesting their information from a background thread without locking. Additionally, the arrays should always be initialized fully before being set in place.

Prototype f32x4.nearest on ARM for both ARM v7 and ARM v8. ARM v8 has support for vrintn, and for ARM v7 we fallback to runtime. Since ARM v8 uses vrintn, which is the same instruction used for F32RoundTiesEven (scalar), wasm-compiler reuses the Float32RoundTiesEven check.
