Function grouping is disabled.

Description

This option enables or disables function grouping if profiling information is enabled.

A "function grouping" is a profiling optimization in which entire routines are placed either in the cold code section or the hot code section.

If profiling information is enabled by option -prof-use, option -prof-func-groups is set and function grouping is enabled. However, if you explicitly enable -prof-func-order, function ordering is performed instead of function grouping.

If you want to disable function grouping when profiling information is enabled, specify -no-prof-func-groups.

To set the hotness threshold for function grouping, use option -prof-hotness-threshold.
