Qcov-gen

Produces an instrumented object file that can be used with the codecov or tselect tool.

Syntax

Linux and macOS:
None
Windows:
/Qcov-gen
/Qcov-gen-
Arguments
None
Default
/Qcov-gen-
The instrumented object file is not produced.
Description
This option produces an instrumented object file that can be used with the code-coverage tool (codecov) or the test prioritization tool (tselect). The instrumented code is included in the object file in preparation for instrumented execution.
This option also creates a static profile information file (.spi) that can be used with the codecov or tselect tool.
Option
/Qcov-gen
should be used to minimize the instrumentation overhead if you are interested in using the instrumentation only for code coverage. You should use
/Qprof-gen:srcpos
if you intend to use the collected data for code coverage and profile feedback.
Alternate Options
None

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
