The compiler embeds software pipelined loop information in the .asm file. This information is used to optimize C/C++ code.
The software pipelining information appears as a comment in the .asm file before a loop and for the assembly optimizer the information is displayed as the tool is running. Example 1 illustrates the information that is generated for each loop.
The --debug_software_pipeline option adds additional information displaying the register usage at each cycle of the loop kernel and displays the instruction ordering of a single iteration of the software pipelined loop.
