Johnny Chen b5825b82ad Minor change for the @expectedFailureClang logic. For the non-clang test failure, re-raise
the exception to get more stack trace information.

Enrico Granata 02b6676d2b Third round of code cleanups:
- reorganizing the PTS (Partial Template Specializations) in FormatManager.h
 - applied a patch by Filipe Cabecinhas to make LLDB compile with GCC
Functional changes:
 - fixed an issue where command type summary add for type "struct Foo" would not match any types.
   currently, "struct" will be stripped off and type "Foo" will be matched.
   similar behavior occurs for class, enum and union specifiers.

Johnny Chen 31963cea0a Add a decorator for marking clang only expectedFailure. Use it for the test_step_over_3_times_with_dsym/dwarf()
test cases in TestThreadAPI.py by decorating it with @expectedFailureClang.

Example:

    @expectedFailureClang
    @python_api_test
    def test_step_over_3_times_with_dwarf(self):
        """Test Python SBThread.StepOver() API."""
        # We build a different executable than the default buildDwarf() does.
        d = {'CXX_SOURCES': 'main2.cpp', 'EXE': self.exe_name}
        self.buildDwarf(dictionary=d)
        self.setTearDownCleanup(dictionary=d)
        self.step_over_3_times(self.exe_name)

Jakob Stoklund Olesen 9eb77bf615 Don't treat a partial <def,undef> operand as a read.
Normally, a partial register def is treated as reading the
super-register unless it also defines the full register like this:

  %vreg110:sub_32bit<def> = COPY %vreg77:sub_32bit, %vreg110<imp-def>

This patch also uses the <undef> flag on partial defs to recognize
non-reading operands:

  %vreg110:sub_32bit<def,undef> = COPY %vreg77:sub_32bit

This fixes a subtle bug in RegisterCoalescer where LIS->shrinkToUses
would treat a coalesced copy as still reading the register, extending
the live range artificially.

My test case only works when I disable DCE so a dead copy is left for
RegisterCoalescer, so I am not including it.

Dan Gohman b38940135b Track a retain+release nesting level independently of the

Bill Wendling c61f7659ba Intelligently split the landing pad block.
We have to be careful when splitting the landing pad block, because the
landingpad instruction is required to remain as the first non-PHI of an invoke's
unwind edge. To retain this, we split the block into two blocks, moving the
predecessors within the loop to one block and the remaining predecessors to the
other. The landingpad instruction is cloned into the new blocks.

Bill Wendling ca7d309623 Add SplitLandingPadPredecessors().
SplitLandingPadPredecessors is similar to SplitBlockPredecessors in that it
splits the current block and attaches a set of predecessors to the new basic
block. However, it differs from SplitBlockPredecessors in that it's specifically
designed to handle landing pad blocks.

Two new basic blocks are created: one that is has the vector of predecessors as
its predecessors and one that has the remaining predecessors as its
predecessors. Those two new blocks then receive a cloned copy of the landingpad
instruction from the original block. The landingpad instructions are joined in a
PHI, etc. Like SplitBlockPredecessors, it updates the LLVM IR, AliasAnalysis,
DominatorTree, DominanceFrontier, LoopInfo, and LCCSA analyses.

Bruno Cardoso Lopes 5647d84aa4 Re-encoded 128-bit AVX versions of SQRT, RSQRT, RCP have 3 operands
instead of 2. They were already defined this way in their regular
version, but not for the intrinsics versions (*_Int), and that would work
for assembly emission but not for object code, since a MachineOperand
would be missing. This commit fix PR10697.

Also removed the {VSQRT,VRSQRT,VRCP}r_Int forms and match the intrinsic
via INSERT_SUBREG+EXTRACT_SUBREG patterns. The same couldn't be done for
memory versions because sse_load_f32/sse_load_f64 operand need special
handling and don't work like regular "addr" operands.

There are right now 114 "*_Int" and 98 "Int_*" forms! I'm slowly
removing them as I step through, but hope we can get rid of these
someday, they are really annoying :)

Ivan Krasin 44306e2e5f Add NativeClient operating system support.
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

An example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 20 -p '-\[NSArray .+\]'

disassembles the first 20 NSArray instance methods found in the CoreFoundation module.

Anna Zaks f4dd4ae7cc Static Analyzer Diagnostics: Move custom diagnostic visitors from BugReporterContext to BugReport.
One API change: I added BugReporter as an additional parameter to the BugReporterVisitor::VisitNode() method to allow visitors register other visitors with the report on the fly (while processing a node). This functionality is used by NilReceiverVisitor, which registers TrackNullOrUndefValue when the receiver is null.

Chad Rosier 222e187e33 Temporarily revert r137925 to appease buildbots. Original commit message:
Teach ModuleManager::addModule() to check whether a particular module
has already been loaded before allocating a new Module structure. If
the module has already been loaded (uniquing based on file name), then
just return the existing module rather than trying to load it again.

This allows us to load a DAG of modules. Introduce a simple test case
that forms a diamond-shaped module graph, and illustrates that a
source file importing the bottom of the diamond can see declarations
in all four of the modules that make up the diamond.
