This allows us to assert at compile time that a class instance is assigned, which is particularly useful for Guard classes.

Prototype v128.load{8,16,32,64}_lane on IA32 (stores will come later). This is pretty similar to x64 version, except that there is no signal handler for OOB access, so kProtected is not a valid access mode. Left some TODOs for myself to merge the new instruction codes (kIA32Pinsrb) with the replace lane Wasm instructions.

This change refactors the v8.h API as discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY/edit#heading=h.q0c9h4p928mn such that a v8::Module exposes module requests as a FixedArray of ModuleRequest objects, which can then be used to obtain their module specifier and source code offset. This replaces the old functions that passed back individual specifier Strings and Locations via repeated calls to getters that take an index. These are marked as deprecated. The new ModuleRequest interface includes a getter for an ImportAssertions FixedArray, which will contain the import assertions for the request if --harmony-import-assertions is set, and will be empty otherwise. One notable change here is that the APIs now return source code offsets rather than v8::Locations. The host must then call the new Module::SourceOffsetToLocation to convert these offsets into line/column numbers. This requires a bit more back-and-forth, but allows the host to defer the cost of converting from source offset to line/column numbers until an error needs to be reported, potentially skipping the work altogether.

Leszek Swirski authored
Add a CompareCharsEqual to complement CompareChars, where we only care about equality and not ordering. For such cases, we can memcmp for two- byte as well as one-byte strings (we can't for CompareChars because the ordering would be incorrect on little-endian systems). Replace uses of CompareChars that only compare the result against zero, with CompareCharsEqual. Additionally, use some template magic to simplify the "make unsigned" operation in these methods.

Make String::IsEqualTo use a direct string shape dispatch and a direct call to CompareChars, rather than splitting the behaviour over IsOneByte/IsTwoByte/HasOneBytePrefix. Avoiding GetFlatContent will make this method easier to make efficient while staying string-access-lock safe. Also, redefines the sequential string table key's matcher in terms of this IsEqualTo method.

This CL prepares the interpreter for 64-bit addresses. The offset (in the memory immediate) can now be 64-bit, and also the index (from the stack) will be 64-bit if memory64 is enabled. memory.size will return a 64-bit constant under memory64. memory.grow is a bit more involved and requires more refactorings in the called functions. I left a TODO in the interpreter for now.

For pages that are already swept, it can happen that one thread iterates old-to-new-slots while another thread promotes an object onto the same page. Accessing the slot_set in Scavenger::ScavengePage therefore needs to be atomic.

The Code object returned by CompileOptimized runtime functions is tail-called to continue execution. This Code object should not be the CompileLazy builtin. We ran into this case when the requested code kind was available, but not attached - here we returned early from Compiler::CompileOptimized without doing anything. To satisfy the postcondition, this CL removes the early exit and lets GetOptimizedCode handle the cached cases (both the FeedbackVector's optimized code cache, and the isolate cache).
