`l.nop 9'
Instruction tracing is turned off.
 
`l.nop 10'
A 32-bit random number is returned in `r11'.
 
The random numbers are generated using `random', which in turn is
seeded through `srandom' using the host `/dev/urandom' if
available, or else the process ID of the Or1ksim instance.
 
This opcode is particularly useful for situations where a target
program running on Or1ksim needs to obtain genuine system entropy
to generate random numbers.
 
`l.nop 11'
Return a non-zero value in `r11'.
 
This opcode can be used to detect if a target is running under
Or1ksim. Set `r11' to zero, issue this opcode, and look to see if
`r11' is non-zero.

Instruction tracing is turned off.
 
@item l.nop 10
@cindex @code{l.nop 10} (return a random number)
 
A 32-bit random number is returned in @code{r11}.
 
The random numbers are generated using @code{random}, which in turn is
seeded through @code{srandom} using the host @file{/dev/urandom} if
available, or else the process ID of the @value{OR1KSIM} instance.
 
This opcode is particularly useful for situations where a target
program running on Or1ksim needs to obtain genuine system entropy to
generate random numbers.
 
@item l.nop 11
@cindex @code{l.nop 11} (return a non-zero value)
 
Return a non-zero value in @code{r11}.
 
This opcode can be used to detect if a target is running under
Or1ksim. Set @code{r11} to zero, issue this opcode, and look to see

"l.nop 1", which will cause the simulator to exit. Good for tracking pointer
corruption.
 
New l.nop opcodes to turn instruction tracing on and off. Good for debugging
applications.
 
New l.nop opcode to return a random number. Good for applications (like the
Linux kernel) which need access to the host entropy to ensure randomness.
 
New l.nop opcode to identify that this is an Or1ksim session. Allows
applications to determine if they are running on Or1ksim or hardware.
 
 
New in release 0.5.0rc2
