Add Claude Explain feature for AI-powered code explanations This PR introduces Claude Explain, a new feature that provides AI-powered explanations of compiler output directly within Compiler Explorer. Key features: Claude Explain functionality: - New explain view pane - Explains compiler output with full context of source code and compilation output - Configurable audience level and explanation type - Response caching to improve performance and reduce API calls - Usage statistics display showing requests used and token counts User experience: - Consent flow on first use explaining data handling and privacy - AI disclaimer banner warning about potential LLM inaccuracies - Respects "no-ai" directive in source code for users who don't want AI processing Privacy and security: - Data sent to Anthropic's Claude API as documented in privacy policy - No data used for model training - Clear consent required before first use - Support for opting out via "no-ai" directive The feature is marked as beta and can be enabled via configuration.

How do I ?
This is a how-to guide for the user-interface presented by Compiler Explorer. This doesn't cover the details of how to set up or modify Compiler Explorer for your own needs. For that, please check the documents which already cover topics like:
- Adding a language
- Adding a compiler
- Adding a library
- Adding a tool
- and many more at compiler-explorer/docs

Change the assembly syntax from Intel
The option to switch assembly from Intel to AT&T syntax is present in the Output option of each compiler. If enough
space is not present, the option also presents itself as the gear symbol (⚙)
Compare the time taken by compilation and networking
This is the symbol that looks like a bar graph (📊). If your compilations are taking long, you can use this to check the time taken by:
- Networking, JavaScript, waiting for events, etc.
- Checking the cache and retrieving from it on a cache-hit
- Compilation (on force compilation or cache-miss)
- Parsing the generated assembly before presenting it
View intermediate information provided by the compilers
Though both GCC and Clang create supplementary outputs along with assembly (shown by default), and an executable (created if an executor has been added), the exact nature of the outputs and their formats differ between the compilers.
GCC allows the Tree, IPA, RTL and graph outputs, while Clang allows optimization, AST, IR and graph outputs. Some outputs (e.g. RTL or graph) also have a rich set of options in the UI to enable focussing on a particular function or compiler stage.
