Fwd: Problems when use OpenACC with a Kernel

[Thomas Schwinge]

Hi Esteban!

Please in the future use the <gcc-help@gcc.gnu.org> for getting help with
GCC (HTML email will be discarded, if I remember correctly).

A first try at answering your question:

Thanks for your interest in trying this!

How do you configure/build?  I'm asking because:

So, you got PTX assembly code in your target (presumably x86_64?)
assembly code -- something is wrong with your GCC build configuration, so
we need to clarify that first.  (I do acknowledge that it's a bit
complicated...)
