Windows:
/Qprof-value-profiling
[
:
keyword
]
Arguments
keyword
Controls which type of value profiling is performed. Possible values are:
none
Prevents all types of value profiling.
nodivide
Prevents value profiling of non-compile time constants used in division or remainder operations.
noindcall
Prevents value profiling of function addresses at indirect call sites.
all
Enables all types of value profiling.
You can specify more than one keyword, but they must be separated by commas.
Default
all
All value profile types are enabled and value profiling is performed.
Description
This option controls which features are value profiled.
If this option is specified with option
[Q]prof-gen
, it turns off instrumentation of operations of the specified type. This also prevents feedback of values for the operations.
If this option is specified with option
[Q]prof-use
, it turns off feedback of values collected of the specified type.
If you specify level 2 or higher for option
[q or Q]opt-report
, the value profiling specialization information will be reported within the PGO optimization report.

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.
