Syntax
EXTENDED-VTF
Variable
VT_EXTENDED_VTF
Default
off
in Intel Trace Collector,
on
in stftool.
Description
Several events can only be stored in STF, but not in VTF. The Intel Trace Collector libraries default to writing valid VTF trace files and thus skip these events. This option enables writing of non-standard VTF records in ASCII mode that Intel Trace Analyzer would complain about. In the stftool the default is to write these extended records, because the output is more likely to be parsed by scripts rather than by Intel Trace Analyzer.

Product and Performance Information

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.
