<div>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

Hi, yes, these patches are
required to have tne basic debug

patches are required to be able to
