Syntax
ENTER-USERCODE [on|off]
Variable
VT_ENTER_USERCODE
Default
on
in most cases,
off
for Java* function tracing
Description
Usually the Intel Trace Collector enters the
Application:User_Code
state automatically when registering a new thread. This makes little sense when function profiling is enabled, because then the user can choose whether he wants the
main()
function or the entry function of a child thread to be logged or not. Therefore it is always turned off for Java* function tracing. In all other cases it can be turned off manually with this configuration option.
However, without automatically entering this state and without instrumenting functions threads might be outside of any state and thus not visible in the trace although they exist. This may or may not be intended.

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.
