This introduces a new library to LLVM: libDebugInfo. It will provide debug information
parsing to LLVM. Much of the design and some of the code is taken from the LLDB project.

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.

It is an endian-aware helper that can read data from a StringRef. It will
come in handy for DWARF parsing. This class is inspired by LLDB's
DataExtractor, but is stripped down to the bare minimum needed for DWARF.

Comes with unit tests!

more strict about the alignment checking. This was found by inspection
and I don't have any testcases so far, although the llvm testsuite runs
without any problem.

This is consistent with the behavior of assigning into a __strong l-value,
and it's also necessary for ensuring that the ivar doesn't end up a dangling
reference.  We decided not to change the behavior of "retain" properties, but
just to make them warnings/errors when of block type.

Depends on a llvm tablegen commit.

Get the address and the size of the variable for passing to the Target::CreateWatchpointLocation() method.

should no longer have the serialization of LangOptions out of sync
with the structure itself (yay).

llvm-svn: 139613

This function is used to flag values where the complement interval may
overlap other intervals.  Call it from overlapIntv, and use the flag to
fully recompute those live ranges in transferValues().

Thread safety: Initializing var before exhaustive switch statement to deal with extraneous warning produced by gcc but not clang

Teach the Thumb ASM parser that BKPT is allowed in IT blocks, even though it is always executed unconditionally.

-Allow cursor visitation of an attribute using its source range
-Add C++ 'final' and 'override' attributes as cursor kinds
-Simplify the logic that marks 'final' and 'override' attributes as tokens.

language options. Use that .def file to declare the LangOptions class
and initialize all of its members, eliminating a source of annoying
initialization bugs.

AST serialization changes are next up.

Three out of four clients prefer this interface which is consistent with
extendIntervalEndTo() and LiveRangeCalc::extend().

llvm-svn: 139604

The complement interval may overlap the other intervals created, so use
a separate LiveRangeCalc instance to compute its live range.

A LiveRangeCalc instance can only be shared among non-overlapping
intervals.

In Microsoft mode, downgrade "goto into protected scope" from error to warning if we are jumping over a variable initialization via a goto.

This fixes a few errors when parsing MFC code with clang.

This deletes a bunch of crufty code, and allows more logic sharing
between the analyzer and the warnings.

Only disassembler instructions with vvvv != 1111 if the instruction actually uses the vvvv field to encode an operand. Fixes PR10851.

even on architectures that support unaligned access (which is the
only way this is otherwise legal, given that ivars apparently do
not honor alignment attributes).

llvm-svn: 139589

Remove filter that was preventing MOVDQU/MOVDQA and their VEX forms from being disassembled. Also added encodings for the other register/register form of these instructions. Fixes PR10848.

llvm-svn: 139588

Fix encoding of VMOVDQU to not simultaneously be 'TB OpSize' and 'XS'. 'XS' is correct and seems to have been taking priority.
