Victor Gomes authored
The arm/arm64 simulators debugger has a command "mem" that prints the content of the memory. It also prints a short summary for JS objects (SMI, Array, JSFunction, ...). That is very handy, but when trying to print incomplete initialized memory, it could raise an exception. It is useful to have a command that prints the content of the memory for non-initialized or bogus values without the risk of raising an exception. This CL adds the command "dump".

port 9d3dc6f2 https://crrev.com/c/1914218 Original Commit Message: FunctionEntry StackChecks is one of the two cases where we generate a StackCheck bytecode. In these cases, we do stack check against the js limit (not to be confused with the real js limit). Their purpose is to be able to interrupt the running code. We can omit the FunctionEntry StackCheck by embedding its code into the InterpreterEntryTrampoline builtin. We save one bytecode per interpreted function. This change has rippling effects for optimized code, as well as the deoptimizer.

Since the size of the parameters and locals inputs is already stored on the FrameStateFunctionInfo, this skips the calls to size() and just reuses the previous values. The stack parameter can only have a size of 0 or 1 depending on whether it's a InterpretedFunction frame or not. It also extends the verifier to check that the values to match those returned by StateValueAccess::size and changes a unit test that added a TypedStateValues of size 2 to the stack input.

This skips gay-*.cc cctest files for lint checking. The files contain 99.9% data not structures. Alternatively, maybe the data could be moved to non-cc resource files. This speeds up v8_presubmit without caching locally from 39s to 23s. This is how it's executed on the continuous CI builder.

The previous code was relying on {compilation_unit_builder_} to check if a section was after or before the code section. This only works for the first section after code section, since the compilation unit builder is then reset. Use an additional field to track this instead.

These tests are likely missing %PrepareFunctionForOptimization annotation of lambdas. Thus lambdas are no longer inlined and %DeoptimizeNow does nothing, while the entire point of these tests is to test deoptimization paths. Disabling lazy feedback allocation is a quick fix to restore coverage until we can land a more complete fix (for details see the linked bug).
