ModRef Function Effect Specifications
The include/Annotation/ModRef/ headers define the external mod/ref summary
format used to model library functions for alias and checker pipelines.
Location: include/Annotation/ModRef/
Main APIs:
ModRefEffectandModRefEffectSummarydescribe a function’s memory reads and writes.ExternalModRefTableloads and stores per-function summaries.ExternalModRefTablePrinteremits human-readable tables for debugging.
What it models:
Direct-memory versus reachable-memory effects.
Argument and return positions through
APosition.External summaries for functions whose bodies are unavailable.
Used by:
Alias analyses that need library-side memory effects.
Bug-finding and verification passes that need consistent side-effect models.
