Inspector on a proxy to a CompiledMethod, showing all bytecodes and their sendAndBranchData.

Inspector on a proxy to a Morph from the simulated image, showing a screenshot rendered in the host image.
|
|
|
This screencast shows how our proxy inspector can be used to inspect a morph from a simulated VM:

Inspector on a proxy to a CompiledMethod, showing the address of the OOP in the simulated VM.

Inspector on a proxy to a CompiledMethod, explaining the header format of the OOP in the simulated VM.

Inspector on a proxy to a CompiledMethod, showing its just-in-time generated cog method.
|
Inspector on a generated cog method, showing its disassembled and styled assembler code. |

This screencast shows how Scorch is triggered by a counter trip and how to use our extended inspectors with code artifacts:

Debugger on a proxy to a CompiledMethod, executing its bytecodes in the metacircular interpreter of the host image.
|
Debugger on a proxy to a Context, revealing the call stack of the active process in the simulated VM.
|
|
|
This screencast shows how we can spawn a debugger on a Context that runs a simulated CompiledMethod and how that can be used to iteratively implement the in-image simulation capabilities for SistaV1 bytecodes:
debugger-on-method-proxy.mp4
This screencast shows how the the debugger idea can be extended to view simulated stack traces (this should currently be done in a read-only fashion, writing to simulated contexts will currently most likely produce errors):

This screencast shows how our new bytecode assembler mode can help with experimenting with (SistaV1) bytecodes:

Proof that Oopsie can run the JSON Benchmark from the AWFY Benchmarks in the Simulator, triggering Scorch many times and thus producing optimized JSON parsing methods:
