Compiler Personality Generator 2.0

Compiler Personality Generator by PR:QA

A lightweight, developer-friendly tool that builds accurate “compiler personalities” so your static analysis and build simulations reflect the real behavior of your target toolchains. Compiler Personality Generator discovers and captures each compiler’s dialect, extensions, predefined macros, data-model specifics, and diagnostic mappings, then outputs a reusable profile you can share across teams and pipelines.

Who it’s for

• C/C++ teams who rely on consistent, reproducible analysis across multiple compilers or versions
• Embedded and safety-critical projects that must model vendor-specific extensions and pragmas
• Organizations standardizing analysis baselines in CI/CD

Key features

• Automatic discovery: Scans toolchains to detect language extensions, predefined macros, sizes and alignments, char signedness, packing, and pragma behavior.
• Diagnostic mapping: Aligns warning and error categories with your analysis rules to reduce noise and false positives.
• Multi-compiler support: Works with common desktop and embedded compilers (for example, GCC, Clang/LLVM, MSVC, Arm, IAR, TI, Green Hills).
• Profile validation: Verifies generated personalities against sample code to ensure faithful modeling.
• Flexible outputs: Exports versioned profiles (e.g., JSON/YAML) suitable for PR:QA workflows and easy review in source control.
• CI/CD ready: Command-line interface and non-interactive mode for automated generation and enforcement in pipelines.
• Change tracking: Diff personalities between compiler versions or flag sets to understand impact before you upgrade.

Benefits

• Consistent, comparable analysis results across toolchains and teams
• Faster onboarding for new platforms and compiler versions
• Fewer false positives and clearer findings by matching true compiler behavior
• Traceable, auditable configurations that support standards compliance

How it works

1. Point the tool at your compiler (and typical flags).
2. Generate a personality profile capturing its behavior.
3. Apply the profile in your analysis workflow to mirror the target build with confidence.

Deliver reliable results from your analysis by modeling the compiler that actually builds your code—quickly, accurately, and repeatably.
