The Disassembly view shows a disassembly listing of the object file containing the selected function, annotated with performance metrics for each instruction. You might need to select Machine from the View Mode list in the toolbar to see the disassembly listing.
Interleaved within the disassembly listing is the source code, if available, and any compiler commentary chosen for display. The algorithm for finding the source file in the Disassembly view is the same as the algorithm used in the Source view.
Just as with the Source view, index lines are displayed in Disassembly view. But unlike with the Source view, index lines for alternate source contexts cannot be used directly for navigation purposes. Also, index lines for alternate source contexts are displayed at the start of where the #included or inlined code is inserted, rather than just being listed at the beginning of the Disassembly view.
Code that is #included or inlined from other files shows as raw disassembly instructions without interleaving the source code. However, placing the cursor on one of these instructions and selecting the Source view opens the source file containing the #included or inlined code. Selecting the Disassembly view with this file displayed opens the Disassembly view in the new context, thus displaying the disassembly code with interleaved source code.
You can set the classes of commentary that are displayed in the Settings dialog box. The default classes can be set in a .er.rc defaults file by clicking the Save button in the dialog box.
Performance Analyzer highlights hot lines, which are lines with metrics that are equal to or exceed a metric-specific threshold, to make it easier to find the important lines. You can set the threshold in the Settings dialog box.
As with the Source view, yellow navigation markers are shown in a margin next to the scrollbar on the right for each source line with metrics. Non-zero metrics that are below the hot threshold are not highlighted but are flagged with yellow navigation markers. To quickly navigate to source lines with metrics, you can click the yellow markers in the right margin to jump to the lines with metrics. You can also right-click the metrics themselves and select an option such as Next Hot Line or Next Non-Zero Metric Line to jump to the next line with metrics.
