Hi, yes, these patches are required to have tne basic debug info support. At least 2 more patches are required to be able to get values of the variables without additional manual data type casting in cuda-gdb.

Hi Alex, Eric and Valentin, Thanks for the information. I don't mean to push this but I'm in desperate need of debugging some cuda code. I'm not familiar with the llvm internal but it sounds like there's at least line info now, right? If so, can you point me to a branch of llvm that can help tracing the bug down to certain line of code. I believe my bug is simply a write/read out of array boundary.
