be a smi. The inlined version works for stores to JSArrays where the key is a smi that is within bounds of the array and the value is either constant or a smi so we can skip the write-barrier.

* Identify heap numbers that contain non-Smi int32s and do bit ops on them without calling the fp hardware or emulation. * Identify results that are non-Smi int32s and write them into heap numbers without calling the fp hardware or emulation. * Do unary minus on heap numbers without going into the runtime system. * On add, sub and mul if we have both Smi and heapnumber inputs to the same operation then convert the Smi to a double and do the op without going into runtime system. This also applies if we have two Smi inputs but the result is not Smi.

instructions. The intention is that the snapshots generated by the simulator should be usable on the hardware. Instead of swi instructions we generate a branch to a swi instruction that is not part of the snapshot. The call/jump is patched up in the same way as other external references when the snapshot is deserialized. This only works for EABI targets: on old ABI targets we still emit some instructions not supported by the simulator (fp coprocessor instructions).

This is a trivial per-row compression: - short aliases are introduced for events and code creation tags; - in tick events, offsets are used instead of absolute addresses; - removed 'code-allocation' event, as it seems not used. The first two options are depend on the new flag: 'compress-log', which is off by default. On benchmarks run w/o snapshot, this gives 45% log size reduction.

Scripts now have a compilation type which can be host, eval or JSON. Host scripts are compiled through the API, eval scripts are compiled through call to evan and JSON scripts are compiled as a result of calling JSON.parse. For scripts scripts compiled through eval the JavaScript function in top of the stack and the pc offset into the code is stored in the script object. This makes it possible to calculate the source position of the eval call later when requested. This information can be obtained through the script mirror object and is part of the script mirror JSON serialization for the debugger protocol. Moved the enumeration ScripType into class Script and remamed to Type. The new compilation type enumeration is also inside the class Script. This information is now shown when using the scripts command in he developer shell debugger.

cache to 5 (down from 8). Generations 5, 6, and 7 are rarely hit in real browsing sessions (~2% in the best case) so it seems better to lower the size to avoid carrying around too many compiled scripts in the cache.

deferred code snippets are highly stylized. They always make a call to a stub or the runtime and then return. This change takes advantage of that. Creating a deferred code object now captures a snapshot of the registers in the virtual frame. The registers are automatically saved on entry to the deferred code and restored on exit. The clients of deferred code must ensure that there is no change to the registers in the virtual frame (eg, by allocating which can cause spilling) or to the stack pointer. That is currently the case. As a separate change, I will add either code to verify this constraint or else code to forbid any frame effect. The deferred code itself does not use the virtual frame or register allocator (or even the code generator). It is raw macro assembler code.

The problem was I incorrectly treated NULL result as failure to fetch a property with a getter. However, if getter returns zero, it is manifested as NULL pointer (see added test case). Good news: that gives another boost as before this CL if getter returned 0, I did another slow lookup.
