Added test to check that each thread reported by $q{f,s}ThreadInfo
can be switched to by $Hg, verified by a follow-up $qC.

Modified test exe to accept "thread:new" to create a new thread

@llgs_test/@debugserver_test now buffer output.
   
llgs and debugserver gdbremote protocol tests now collect $O notification
output into the context returned from expect_lldb_gdbserver_replay.
context["O_count"] is an integer indicating the number of $O packets
collected during the replay, and context["O_content"] contains the
accumulated hex-decoded text output by the inferior (stdout and stderr).

Modified the $O check test to check the accumulated output rather than
a direct $O packet.

Reid Kleckner 563f0e852c Use comdats to avoid double initialization of weak data
Initializers of global data that can appear multiple TUs (static data
members of class templates or __declspec(selectany) data) are now in a
comdat group keyed on the global variable being initialized.  On
non-Windows platforms, this is a code size and startup time
optimization.  On Windows, this is necessary for ABI compatibility with
MSVC.

Fixes PR16959.

David Blaikie 2f75351c02 DebugInfo: Generalize some tests to handle variations in attribute ordering.
In an effort to fix inlined debug info in situations where the out of
line definition of a function preceeds any inlined usage, the order in
which some attributes are added to subprogram DIEs may change. (in
essence, definition-necessary attributes like DW_AT_low_pc/high_pc will
be added immediately, but the names, types, and other features will be
delayed to module end where they may either be added to the subprogram
DIE or instead reference an abstract definition for those values)

These tests can be generalized to be resilient to this change. 5 or so
tests actually have to be incompatibly changed to cope with this
reordering and will go along with the change that affects the order.

Richard Smith 871cd4c131 [modules] If a referenced-but-not-instantiated class template specialization
gets explicitly specialized, don't reuse the previous class template
specialization declaration as a new declaration. The benefit here is fairly
marginal, it harms source fidelity, and this is horrible to model if the
specialization was imported from another module (without this change, it
asserts or worse).

Hans Wennborg a926d84c4b Emit used/dllexport inline method definitions in nested classes (PR19743, PR11170)
The previous code that was supposed to handle this didn't work
since parsing of inline method definitions is delayed to the end
of the outer class definition. Thus, when HandleTagDeclDefinition()
got called for the inner class, the inline functions in that class
had not been parsed yet.

Richard suggested that the way to do this is by handling inline
method definitions through a new ASTConsumer callback.

I really wanted to call ASTContext::DeclMustBeEmitted() instead of
checking for attributes, but doing that causes us to compute linkage,
and then we fail with "error: unsupported: typedef changes linkage
of anonymous type, but linkage was already computed" on tests like
this: (from SemaCXX/undefined-internal.cpp) :-/

  namespace test7 {
    typedef struct {
      void bar();
      void foo() { bar(); }
    } A;
  }

David Blaikie 169ffe41af DebugInfo: Put concrete definitions referencing abstract definitions in the same scope as the abstract definition.
This seems like a simple cleanup/improved consistency, but also helps
lay the foundation to fix the bug mentioned in the test case: concrete
definitions preceeding any inlined usage aren't properly split into
concrete + abstract (because they're not known to need it until it's too
late).

Once we start deferring this choice until later, we won't have the
choice to put concrete definitions for inlined subroutines in a
different scope from concrete definitions for non-inlined subroutines
(since we won't know at time-of-construction which one it'll be). This
change brings those two cases into alignment ahead of that future
chaneg/fix.

Hans Wennborg be4be16be3 Don't suppress warning about dllimport on typedefs etc. in MicrosoftExt mode
It's true the MSVC doesn't warn about dllimport when applied to e.g. a typedef,
but that applies to dllexport too. I'd like us to be consistent, and I think
the right thing to do is to warn.

The original test that came with implementing the old behaviour doesn't provide
a good motivation, and it said it was checking that we're not repoting an *error*,
which is still true since this is just a warning.

There are plenty of tests e.g. in Sema/dllimport.c to check that we do warn
about dllimport on non functions or variables.

This is a follow-up to r209358: PR19799: Indvars miscompile due to an
incorrect max backedge taken count from SCEV.

That fix was incomplete as pointed out by Arnold and Michael Z. The

unit tests. This version will also happen to optimize more cases.

Rafael Espindola a5bb2f61cf Use alias linkage and visibility to decide tls access mode.
This matches both what we do for the non-thread case and what gcc does.

With this patch clang would match gcc's behaviour in

static __thread int a = 42;
extern __thread int b __attribute__((alias("a")));
int *f(void) { return &a; }
int *g(void) { return &b; }

if not for pr19843. Manually writing the IL does produce the same access modes.

It is also a step in the direction of fixing pr19844.

Lang Hames 8e30e4b9b7 [RuntimeDyld] Remove relocation bounds check introduced in r208375 (MachO only).
We do all of our address arithmetic in 64-bit, and operations involving
logically negative 32-bit offsets (actually represented as unsigned 64 bit ints)
often overflow into higher bits. The overflow check could be preserved by
casting to uint32 at the callsite for applyRelocationValue, but this would
eliminate the value of the check.

The right way to handle overflow in relocations is to make relocation processing
target specific, and compute the values for RelocationEntry objects in the
appropriate types (32-bit for 32-bit targets, 64-bit for 64-bit targets). This
is coming as part of the cleanup I'm working on.

This fixes another i386 regression test.

Ben Langmuir 5de00f3b56 Stopgap fix for finding module for a file mapped in the VFS
If we lookup a path using its 'real' path first, we need to ensure that
when we run header search we still use the VFS-mapped path or we will
not be able to find the corresponding module for the header.

The real problem is that we tie the name of a file to its underlying
FileEntry, which is uniqued by inode, so we only ever get the first name
it is looked up by. This doesn't work with modules, which rely on a
specific file system structure.  I'm hoping to have time to write up a
proposal for fixing this more permanently soon, but as a stopgap this
patch updates the name of the file's directory if it comes from a VFS
mapping.

Manuel Klimek 5fbdc93d97 Make dead return statement detection more robust against changes in the CFG.
This change is a precondition to the proposed change to handle temporary
dtors correctly.

The idea is to explicitly search for the next return that doesn't have other
paths into it (that is, if the current block is dead, the block containing the
return must be dead, too). Thus, introducing non-control-flow block
transitions will not break the logic.
