1> Use DebugInfoFinder to find debug info MDNodes.
2> Add disable-debug-info-verifier to disable verifying debug info.
3> Disable verifying for testing cases that fail (will update the testing cases
   later on).
4> MDNodes generated by clang can have empty filename for TAG_inheritance and
   TAG_friend, so DIType::Verify is modified accordingly.

Note that DebugInfoFinder does not list all debug info MDNode.
For example, clang can generate:
metadata !{i32 786468}, which will fail to verify.
This MDNode is used by debug info but not included in DebugInfoFinder.
This MDNode is generated as a temporary node in DIBuilder::createFunction
  Value *TElts[] = { GetTagConstant(VMContext, DW_TAG_base_type) };
  MDNode::getTemporary(VMContext, TElts)

Fix FileCheck CHECK-LABEL documentation wording slightly; also mention that it allows error recovery.

llvm-svn: 186628

Because it broke s390x and ppc64-linux buildbots. This reverts commit r186623.

llvm-svn: 186627

Update to more CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error  messages. No functionality change.

All changes were made by the following bash script:

  find test/CodeGen -name "*.ll" | \
  while read NAME; do
    echo "$NAME"
    grep -q "^; *RUN: *llc.*debug" $NAME && continue
    grep -q "^; *RUN:.*llvm-objdump" $NAME && continue
    grep -q "^; *RUN: *opt.*" $NAME && continue
    TEMP=`mktemp -t temp`
    cp $NAME $TEMP
    sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \
    while read FUNC; do
      sed -i '' "s/;\([A-Za-z0-9_-]*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC[:]* *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP
    done
    sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP
    sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP
    sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP
    sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP
    mv $TEMP $NAME
  done

This script catches a superset of the cases caught by the script associated with commit r186280. It initially found some false positives due to unusual constructs in a minority of tests; all such cases were disambiguated first in commit r186621.

Summary:
Dump optional data directory entries in the PE/COFF header, so that
we can test the output of LLD linker. This patch updates the test binary
file, but the source of the binary is the same. I just re-linked the file.
I don't know how the previous file was linked, but the previous file did
not have any data directory entries for some reason.

Disambiguate function names in some CodeGen tests. (Some tests were using function names that also were names of instructions and/or doing other unusual things that were making the test not amenable to otherwise scriptable pattern matching.) No functionality change.

Unfortunately I can't think of a way to get a FILE_TYPE_UNKNOWN on a test.

Windows/Path.inc: Introduce file_type::character_file and file_type::fifo_file in sys::fs::getStatus(HANDLE).

It fixes llvm/test/Other/close-stderr.ll on msys.

FIXME: Provide unittests.

The plan is to use it for clang and lld.

Major behavior changes:
- We can now parse UTF-16 files that have a byte order mark.
- PR16209: Don't drop backslashes on the floor if they don't escape
  anything.

The actual parsing loop was based on code from Clang's driver.cpp,
although it's been rewritten to track its state with control flow rather
than state variables.

Also, fix the namespace for two instructions that I missed previously.

llvm-svn: 186572

The original code only folded SRA into ROTATE ... SELECTED BITS
if there was no outer shift.  This patch splits out that check
and generalises it slightly.  The extra cases aren't really that
interesting, but this is paving the way for RNSBG support.

Extend the previous R.SBG patches to handle XORs.

llvm-svn: 186570

In hindsight, using "RISBG" for something that can be any type of
R.SBG instruction was a bit confusing, so this renames it to RxSBG.
That might not be the best choice either, since there is an instruction
called RXSBG, but hopefully the lower-case letter stands out enough.

While there I fixed a couple of GNUisms that had crept in --
sorry about that!

The N3VDIntnp pattern takes bits<5> and I gave it 6 bits.
