Hi all,
I wrote an assembly code with l.mulu and ran in the openrisc simulator. I found that the simulator aborted abnormally when it run l.mul instruction. I wounder if the simulator does not support it? By the way, which of c code will generate l.mulu operation? I tried the following codes, but it didnot generate the l.mulu operation. unsigned int a; unsigned int b; unsigned int c; c = a * b; Can anyone tell me? Thanks Stephen |

Sorry for typing mistake. It is for l.mulu. Do you have any problem with l.mulu when you run it on the simulator? If you do, what is it? How do you fix it ? Thank you very much. haven't tried it. so can you please post output from simulator (and possibly a short testcase where it fails) and i'll put it on my TODO list. regards, p.

Sorry for typing mistake. It is for l.mulu. Do you have any problem with
l.mulu when you run it on the simulator? If you do, what is it? How do
you fix it ? Thank you very much.

Stephen
