"HW_MUL_SUPPORT" in Nios2-Linux with MMU supported distribution

[Altera_Forum]

All, 

 Can anyone please explain how enabling/disabling "hw_mul_support" in Nios2-Linux with MMU supported distribution works? I'm using embed multiplier supported SOPC system. When I tested multiplication operation using this system with enabling and disabling HW_MUL_SUPPORT, I did not observe any difference between them.  Enabling this support in make menuconfig enables "-mno-hw-mul" flag at compile time. Does it create different multiplication instruction at compile time for multiplication operation? I want to trace the assembly instructions that are used for both enabled/disabled support. Can anyone help me?  Thanks in advance!  Regards, Harshil

If you are compiling your app separately from uClinux-dist, you'll need to set the flag yourself.    --- Quote Start ---  I want to trace the assembly instructions that are used for both enabled/disabled support.
