Problem: Stacks in Call Stack and Bottom-Up Panes Are Different

The
Call Stack
 pane shows more stacks than the call tree in the
Bottom-up
 pane.

Cause

There are several stacks going to the same function, but to different code lines (
call sites
).
The call tree in the
Bottom-up
 pane aggregates these stacks in one line but the
Call Stack
 pane shows each as a separate stack. For more details, see the Call Stacks in the Bottom-up Pane and Call Stack Pane topic.

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.
