Function ordering is disabled. |
This option enables or disables function ordering if profiling information is enabled.
For this option to be effective, you must do the following:
For instrumentation compilation, you must specify option [Q]prof-gen setting srcpos.
For feedback compilation, you must specify [Q]prof-use. You must not use multi-file optimization by specifying options such as [Q]ipo or [Q]ipo-c.
If you enable profiling information by specifying option [Q]prof-use, option [Q]prof-func-groups is set and function grouping is enabled. However, if you explicitly enable the [Q]prof-func-order option, function ordering is performed instead of function grouping.
On Linux* systems, this option is only available for Linux linker 2.15.94.0.1, or later.
To set the hotness threshold for function grouping and function ordering, use option [Q]prof-hotness-threshold.
None
The following example shows how to use this option on a Windows system:
icl /Qprof-gen:globdata file1.c file2.c /Fe instrumented.exe
./instrumented.exe
icl /Qprof-use /Qprof-func-order file1.c file2.c /Fe feedback.exe
The following example shows how to use this option on a Linux system:
icc -prof-gen:globdata file1.c file2.c -o instrumented
./instrumented.exe
icc -prof-use -prof-func-order file1.c file2.c -o feedback
