There are several shader debugger tools/situation dependent on this feature.
e.g. one line like this "s_andn2_b32   vcc_lo, vcc_lo, 0             ;000974: 8A6A806A"
1). we feed the disassembly count "0x000974" to the shader debugger tool to get this line of code execution ,register input and output.
2).Also there is some other shader dump tool,e.g. umr. or windbg  which output a stream of hardware codes,  we can use the hardware code to find matched part of disassembly lines.
3). we also have one shader replacement tool , to drop and replace part of the elf hardware code, if we have full disassembly line with counter and hardware code, it would be handy where to edit hardware code.

Hope it explains.
