Instead of asking the user to specify a single file to output coverage
info and defaulting to STDOUT, llvm-cov now creates files for each
source file with a naming system of: <source filename> + ".llcov".

This is what gcov does and although it can clutter the working directory
with numerous coverage files, it will be easier to hook the llvm-cov
output to tools which operate on this assumption (such as lcov).

Added MachineBlockFrequencyInfo::view for displaying the block frequency propagation graph via graphviz.

This is useful for debugging issues in the BlockFrequency implementation
since one can easily visualize where probability mass and other errors
occur in the propagation.

This is the MI version of r194654.

lookup, if parsing failed, we did not restore the lexer state properly, and
eventually crashed.  This change ensures that we always consume all the tokens
from the new token stream we started to parse the name from inline asm.

class entity through debug info. No functional change.

Each line stores all the blocks that execute on that line, instead of
only storing the line counts previously accumulated. This provides more
information for each line, and will be useful for options in enabling
block and branch information.

A few more details on the DataVisualization class in our architectural doc. It is in dire need of expansion, but this is a start at least.

Added GCOVEdge which are simple structs owned by the GCOVFunction that
stores the source and destination GCOVBlocks, as well as the counts.
Changed GCOVBlocks so that it stores a vector of source GCOVEdges and a
vector of destination GCOVEdges, rather than just the block number.

Storing the block number was only useful for knowing the number of edges
and for debug info. Using a struct is useful for traversing the edges,
especially back edges which may be needed later.

Found six (nmostly) identical files named 'test_allocator.h' in the libcxx test suite. Moved one to /support, made it a superset, and removed all but one of the others, and iupdated all the includes. Left the odd one (thread/futures/test_allocator.h) for later.

There are now two functions: readGCNO() and readGCDA().

PPCScoreboardHazardRecognizer was a subclass of ScoreboardHazardRecognizer
which did only one thing: filtered out nodes in EmitInstruction for which
DAG->getInstrDesc(SU) returned NULL. This used to be the case for PPC pseudo
instructions. As far as I can tell, this is no longer true, and so we can use
ScoreboardHazardRecognizer directly.

This should probably be replaced with build infrastructure support for
a platform-specific canonical Python include path, but for now it should
restore the FreeBSD buildbot.

Refactored the work group-related attributes to use a template, which reduces the amount of duplicate code in the handler. No functional change intended.

DebugInfo: Rename generic unit references to "TheU" instead of TheCU now that they might be type units instead of compile units.

CR feedback from Eric Christopher on r196139.

llvm-svn: 196159

Add a helper function getDebugInfoVersionFromModule to return the debug info
version number for a module.

"Verifier/module-flags-1.ll" checks for verification errors.
It will seg fault when calling getDebugInfoVersionFromModule because of the
incorrect format for module flags in the testing case. We make
getModuleFlagsMetadata more robust by checking for error conditions.

The CUDA device attribute doesn't need custom logic to check the number of attribute arguments (the common attribute handler already does this). Switching to use the simple attribute handler. No functional change intended.
