Compiler Root Cause Process

Compiler Root Cause Identification

A root cause analysis is performed by the compiler group for each customer reported defect. This analysis records information about the defect such as:

  • The source location of the defect
  • The date the defect was introduced into the compiler
  • The root cause of the defect
  • Potential countermeasures to address the root cause

This analysis is stored in a database. The database includes a web interface that allows browsing of the data, charting trends, and other metrics.

Implementing Countermeasures

The compiler group maintains a Root Cause Solutions Board whose responsibility is to implement proposed root cause countermeasures. A countermeasure that is approved by the board is incorporated into the compiler development process. The board also holds regular meetings with the compiler group to bring awareness of specific root causes and trends in the root cause database.
