Ben Smith authored
The bulk-memory proposal adds a new DataCount section that declares the number of data segments that are expected to be seen in the Data section. This is similar to the way the number of functions is split between the Function and Code sections. The DataCount section occurs before the Code section, so we can do single-pass validation of the new `memory.init` and `memory.drop` instructions, which have data segment indices as immediates.

Make sure to check that the number of declared functions (specified in the function section) matches the number of function bodies, even if the code section is omitted. Note that it is valid to have a function section with zero declared functions and an omitted code section, and vice versa.

The problem were missing V8_EXPORT_PRIVATE and V8_EXPORT. The unittests test if the trap handler only handles those traps it is supposed to handle: * Only handle traps when the thread-in-wasm flag is set. * Only handle traps of the right type, i.e. memory access violations. * Only handle traps at recorded instructions. The tests also test the consistency of the thread-in-wasm flag. I made one change in the trap handler where that consistency could be violated. All tests are executed with the default trap handler provided by V8, and with the trap handler callback installed in a test signal/exception handler. Patchset 1 is the original CL.

This adds error functions that receive offsets instead of pc, since the streaming compiler stores different sections in different buffers, so computing pointer differences between different sections does not work. We keep the pc-based methods for now to reduce code-churn and complexity at the different call sites.

Swaps around the checks in CompileLazy to ensure we always enter the runtime to lazy compile if a function's SFI is uncompiled. This is necessary with bytecode flushing since the function may have an optimized code marker in the feedback vector, even if the bytecode has been flushed, and we don't want to try to optimize this flushed function.

This CL marks v8::Isolate::GetEnteredContext as deprecated in favor of replacing it with GetEnteredOrMicrotaskContext. Blink no longer uses it, and Node.js does not use this too. GetEnteredOrMicrotaskContext() is relevant for all known cases over GetEnteredContext(), and it costs 2% of a benchmark score to maintain the entered contexts under the nestable microtask context. https://crrev.com/c/1322290 is a context for the bencmark and nestable microtask contexts.
