Instruction Trace View
The
Instruction Trace View
shows the chronological order of instruction calls captured by the Last Branch Record (LBR).
The view contains five columns:
  • Address
    : the assembler instruction address.
    Instructions are grouped by the line number. Expandable
    Address
    items display multiple instructions called from a single code line.
  • Instruction
    : the instruction syntax.
    NOTE
    : If the thread selected in the
    Debug
    view contains no symbols loaded, the following columns are empty.
  • Module
    : the name of the running module.
  • File Name
    : the name of the source code file.
  • Line Number
    : the number of the source file line that calls the instruction.
    To view the line in the source file, double-click the line number. The source file opens in a new view and the selected line is highlighted.
  • File Path
    : path to the source file.
