aview

Aview is a program used for analyzing the output of profile-guided optimization performed by GCC.

Aview generates graphical reports that visualize the profile data and performance improvements achieved by the optimization process.

Aview provides information on branch prediction, inline cost analysis, loop analysis, profile counts, and other optimization-related data.

No, aview can be used with programs written in any language that has been optimized using GCC's profile-guided optimization.

The input data for aview is typically generated by compiling the program with the GCC compiler using the appropriate profiling flags.

Yes, aview allows users to compare performance data between different optimization levels to determine the most effective optimizations.

Aview provides users with customization options to tailor the visualization and analysis based on their specific needs.

Yes, aview allows users to export the generated reports in various formats for further analysis or sharing with team members.

Aview is typically used by advanced developers and performance engineers who are familiar with optimizing compiler techniques.

Yes, documentation for aview can be found on the official GCC website or through Jan Hubicka's own resources.
