Printing dissasembly information in Cuda-gdb

Question

I would like to print information from cuda disassembly.

I am able to print registers in cuda using info registers R1 for example however I am not able to figure out how to print c[0x0][0x20] in (MOV R1, c[0x0][0x20]) or deferenced [R13+0x9f] in (STL.U8 [R13+0x9f], RZ)

Answer 1

When using gdb or cuda-gdb you can use the disass command to disassemble the current code or code at a specific location.

cuda-gdb a.out

debug the program

b main

break in main

r

run the program, when the breakpoint is hit

 disass

disassemble the following code at the breakpoint
