it: |

`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 |
if @code{r11} is non-zero. |
