prof-gen-sampling

Tells the compiler to generate debug discriminators in debug output. This aids in developing more precise sampled profiling output.

Syntax

Linux:
-prof-gen-sampling
macOS:
None
Windows:
None
Arguments
None
Default
OFF
The compiler does not generate debug discriminators in the debug output.
Description
This option tells the compiler to generate debug discriminators in debug output. Debug discriminators are used to distinguish code from different basic blocks that have the same source position information. This aids in developing more precise sampled hardware profiling output.
To build an executable suitable for generating hardware profiled sampled output, compile with the following options:
-prof-gen-sampling -g
To use the data files produced by hardware profiling, compile with option
-prof-use-sampling
.
Alternate Options
None
