Alexander Potapenko 6535f510a3 [ASan] Introduce SymbolizerPrepareForSandboxing(), which is a no-op on every platform except Linux (because we don't support sandboxing anywhere else yet)
On Linux we pre-cache the value of readlink("/proc/self/exe"), so that it can be later used when the sandbox has been turned on.

Manuel Klimek c573080d45 Stop aligning trailing comments which are aligned with the next line.
Previously we would align:
f(); // comment
     // other comment
g();

Even if // other comment was at the start of the line. Now we do not
align trailing comments if they have been already aligned correctly
with the next line.

Thus,
f(); // comment
// other comment
g();
will not be changed, while:
f(); // comment
  // other commment
g();
will lead to the two trailing comments being aligned.

Manuel Klimek 5c24cca0f0 Use a SourceRange for the whitespace location in FormatToken.
Replaces the use of WhitespaceStart + WhitspaceLength.
This made a bug in the formatter obvous where we would incorrectly
calculate the next column.

FIXME: There's a similar bug left regarding TokenLength. We should
probably also move to have a TokenRange instead.

Daniel Jasper e5777d25d6 Improve formatting of braced lists.
Before:
vector<int> x { 1, 2, 3 };
After:
vector<int> x{ 1, 2, 3 };

Also add a style option to remove the spaces inside braced lists,
so that the above becomes:
std::vector<int> v{1, 2, 3};

Manuel Klimek ab41991c07 Expand parsing of braced init lists.
Allows formatting of C++11 braced init list constructs, like:
vector<int> v { 1, 2, 3 };
f({ 1, 2 });

This involves some changes of how tokens are handled in the
UnwrappedLineFormatter. Note that we have a plan to evolve the
design of the token flow into one where we create all tokens
up-front and then annotate them in the various layers (as we
currently already have to create all tokens at once anyway, the
current abstraction does not help). Thus, this introduces
FIXMEs towards that goal.

Bill Wendling 353fbd3516 Performance improvement.
Using fwrite and fread was very *very* slow. The resulting code was multiple
times slower than GCC's implementation of gcov. Replace the fwrite/fread system
with an mmap() version.

If the `.gcda' file doesn't exist, we (re)allocate a buffer that we write
into. That gets written to the `.gcda' file in one chunk. If the `.gcda' file
already exists, we simply mmap() the file, modify the mapped data, and use
msync() to write the contents out to disk. It's much easier than implementing
our own buffering scheme, and we don't have to use fwrite's and fread's
buffering.

For those who are numbers-oriented, here are some timings:

GCC Verison
-----------

`.gcda' files don't exist:  23s
`.gcda' files do exist:     14s

LLVM Version (before this change)
---------------------------------

`.gcda' files don't exist:  28s
`.gcda' files do exist:     28s

LLVM Version (with this change)
-------------------------------

`.gcda' files don't exist:  18s
`.gcda' files do exist:      4s

It's a win-win-win-win-lose-win-win scenario!

Richard Smith 1d209d075b Fix bitcode desynchronization when loading a PCH containing a class template
specialization with modules enabled. Just don't merge them at all for now;
we'll revisit this when support for template merging is added.

In passing, make Decl::dump() a little safer to use with PCH/modules, by making
it not deserialize any additional declarations. From a debugger you can call
decls_begin() or similar first if you want to dump all child decls.

David Blaikie 5174c84add Solidify the assumption that a DW_TAG_subprogram's type is a DW_TAG_subroutine_type
There were bits & pieces of code lying around that may've given the
impression that debug info metadata supported the possibility that a
subprogram's type could be specified by a non-subroutine type describing
the return type of a void function. This support was incomplete &
unnecessary. Asserts & API have been changed to make the desired usage
more clear.

Sean Callanan fbf5c682cb Fixed a bug where persistent variables did not
live as long as they needed to.  This led to
equality tests involving persistent variables
often failing or succeeding when they had no
business doing so.

To do this, I introduced the ability for a
memory allocation to "leak" - that is, to
persist in the process beyond the lifetime of
the expression.  Hand-declared persistent
variables do this now.

Greg Clayton a1b5dd9a20 <rdar://problem/13956179>
Fixed ProcessMachCore to be able to locate the main executeable in the core file even if it doesn't start at a core file address range boundary. Prior to this we only checked the first bytes of each range in the core file for mach_kernel or dyld. Now we still do this, but if we don't find the mach_kernel or dyld anywhere, we go through all core file ranges and check every 0x1000 to see if we can find dyld or the mach_kernel.

Now that we can properly detect the mach_kernel at any address, we don't need to call "DynamicLoaderDarwinKernel::SearchForDarwinKernel(Process*)" anymore.

Bill Schmidt 9b703f9c5d Recognize ValueType operands in source patterns for fast-isel.
Currently the fast-isel table generator recognizes registers, register
classes, and immediates for source pattern operands.  ValueType
operands are not recognized.  This is not a problem for existing
targets with fast-isel support, but will not work for targets like
PowerPC and SPARC that use types in source patterns.

The proposed patch allows ValueType operands and treats them in the
same manner as register classes.  There is no convenient way to map
from a ValueType to a register class, but there's no need to do so.
The table generator already requires that all types in the source
pattern be identical, and we know the register class of the output
operand already.  So we just assign that register class to any
ValueType operands we encounter.

No functional effect on existing targets.  Testing deferred until the
PowerPC target implements fast-isel.
