Shifting signed ULP registers
Shifting signed ULP registers
The ULP registers are stated to be 16 bit signed. Can anyone confirm whether the LSH instruction performs sign-extended or not?

Answer for other's benefit...
The ULP registers are all unsigned, and only immediate values are signed / sign extended.
Note the implication that JUMPR x,0,LT and JUMPR x,-1,GT are never taken.
