This adds the ability to import exception into a module at instantiation time. Only a {WasmExceptionObject} that has been exported by another module instance can be imported, all other values are rejected. Note that currently there is no signature check being performed to make sure the imported exception matches the expected type. Also the identity of imported exceptions is not yet preserved. Furthermore the engine does not yet match thrown exception objects on a global level across modules. Hence imported exceptions will (wrongly) behave as completely new types within the module.

This inserts unreachable node after uncoditional deopt in bit-to-word conversion and wires it as an input to the dead-value. This fixes a problem, where a floating dead-value was inserted by a change of bit-to-word (which always fails because bit cannot be converted to word). Without the unrachable node (which this CL inserts in the effect chain after deopt), the dead value was scheduled before the uncoditional deoptimization and crash at runtime. Unfortunately, I do not know how to construct a test that does not end up in an infinite loop.

To support all possible cases, we must limit the number of register args for TFS builtins on ia32 to 3. Out of the 6 allocatable registers, esi is taken as the context register and ebx is the root register. One register must remain available to store the jump/call target. Thus 3 registers remain for arguments. The reason this applies to TFS builtins specifically is because this becomes relevant for builtins used as targets of Torque function pointers (which must have a register available to store the target).

Previously the builtins table had a value for every single OperandScale/Bytecode combination regardless of whether it was valid. This change makes it so that only valid bytecode handlers are stored in the builtins table. This prevents placeholders being serialized into the snapshot (and embedded into the binary) saving 9KB in CODE_SPACE/OLD_SPACE and 2.5KB in the embedded data as well as 66 entries in the builtins table. To do this, it generates a new header file bytecodes-builtins-list.h which is created from the BYTECODE_LIST and OPERAND_SCALE_LIST macros. Since list macros cannot be used to conditionally generate elements in the C-preprocessor, this is done by generator executable, compiled from interpreter/generate-flat-headers.cc. Additionally the generator creates the flat bytecode list so that it is transposed from the previous result, i.e. the results are grouped by bytecode and then operand scale rather than operand scale then bytecode. This should give better locality for commonly used bytecodes and may allow less commonly used ExtraWide bytecodes to never be mapped into memory at all. The cost to storing the handlers densely is that looking up a handler now requires a binary search through the builtins table, but this should only happen during debugging. It is also fixable at least for non-wide handlers and could be improved for wide ones if the need arises.

This CL makes sure, that logical operators (||, &&) always have return type never. Together with a check that never is never passed as a function argument, this prevents faulty evaluation as in !(x || y). Before, the logical operators had a behavior similar to (bool labels Taken, NotTaken), with a fast exit if the left-hand side allowed shor-circuit evaluation, but returning the right-hand side otherwise. Since we want to allow existing (a || b || c) patterns in the codebase, this requires weakening the restriction that the left- and right-hand side need to have the same type. Now the possibilites are: bool, never never, bool never, never bool, bool constexpr bool, constexpr bool Bug: v8:8137 Change-Id: I9576b337dc4008ac58b4625e77fef4e73bcdd6e3 Reviewed-on: https://chromium-review.googlesource.com/1215162Reviewed-by:
