I'm looking for an example of how to insert a new function into a module. I have a module pass that needs to create some new functions. Tia. Reed

...in the NVPTX back-end to map to the predicate (.pred) type. We definitely do not want to declare this type as illegal. The real issue is lack of complete support for this type. The PTX language places restrictions on what can be done with .pred registers, and it looks like the failure is here: kernelgen_hostcall.exit228: ; preds = %while.cond.i226 store i1 false, i1 addrspace(1)* undef, align 8 Ignoring for a second that you're storing to an undefined address (???), the back-end does not yet handle up-casting an i1 to an appropriate type for storage.

Hi Duncan, Sorry I don't understand your point, could you please explain a little bit more? Why i1 should be declared illegal? Operations on byte-wide types like char or bool are pretty legal, according to PTX spec: "Registers may be typed (signed integer, unsigned integer, floating point, predicate) or untyped. Register size is restricted; aside from predicate registers which are

Hi Dmitry, >> did you declare i1 to be an illegal type? > > No. How? I think it will be considered illegal if you don't add it to any register class.
