in debug sections.
Summary:
This patch works around the bug in the ptxas tool with the processing of bytes
separated by the comma symbol. The emission of the packed string is
temporarily disabled.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
We may end up with not emitted debug directives at the end of the module
emission. Patch fixes this problem emitting those last directives the
end of the module emission.

to update the patch itself after discussion with Eric Christofer.

directives are requested.
Summary:
If the output of debug directives only is requested, we should drop
emission of ',debug' option from the target directive. Required for
supporting of nvprof profiler.

Summary:
If the target does not support `.asciz` and `.ascii` directives, the
strings are represented as bytes and each byte is placed on the new line
as a separate byte directive `.b8 <data>`. NVPTX target allows to
represent the vector of the data of the same type as a vector, where
values are separated using `,` symbol: `.b8 <data1>,<data2>,...`. This
allows to reduce the size of the final PTX file. Ptxas tool includes ptx
files into the resulting binary object, so reducing the size of the PTX
file is important.

debug info emission.""
This reapplies commits: r330271, r330592, r330779.
[DEBUG] Initial adaptation of NVPTX target for debug info emission.
Summary:
Patch adds initial emission of the debug info for NVPTX target.
Currently, only .file and .loc directives are emitted, everything else is
commented out to not break the compilation of Cuda.

info emission."
This appears to have some issues associated with the file directive output
causing multiple global symbols with the name "file" to be emitted into a
startup section. I'm investigating more specific causes and working with the
original author.
This reverts commit r330271.
Also Revert "[DEBUGINFO, NVPTX] Add the test for the debug info of the local"
This reverts commit r330592 and the follow up of 330779 as the testcase is dependent upon r330271.
