Multiple opcodes concatenated by . #8

Closed mahmoodn closed 2 years ago

mahmoodn commented 4 years ago

I would like to know if there is any document about instructions concatenated by . in cuda references? I want to know what is the difference between IMAD and IMAD.WIDE? Specifically for the latter, is that a PTX or SASS instruction? I don't see any instructions named WIDE in the instruction reference.

Closing issue, the documentation of SASS instructions is not public. However, it can be deduced from the documentation of PTX instructions.
