# qopt-report-names, Qopt-report-names

Specifies whether mangled or unmangled names should appear in the optimization report.

## Syntax

Linux: | -qopt-report-names=keyword

macOS: | -qopt-report-names=keyword

Windows: | /Qopt-report-names:keyword

## Arguments

keyword | Specifies the form for the names. You can specify one of the following:
mangled | Indicates that the optimization report should contain mangled names.
unmangled | Indicates that the optimization report should contain unmangled names.

## Default

OFF | No optimization report is generated.

## Description

This option specifies whether mangled or unmangled names should appear in the optimization report. If you use this option, you must specify either mangled or unmangled.

If this option is not specified, unmangled names are used by default.

If you specify mangled, encoding (also known as decoration) is added to names in the optimization report. This is appropriate when you want to match annotations with the assembly listing.

If you specify unmangled, no encoding (or decoration) is added to names in the optimization report. This is appropriate when you want to match annotations with the source listing.

If you use this option, you do not have to specify option [q or Q]opt-report.

When optimization reporting is enabled, the default is -qopt-report-phase=all (Linux* and macOS) or /Qopt-report-phase:all (Windows*).
