c700c4d161 Update the non-pthreads fallback for RWMutex on Unix
Tested this by #if 0'ing out the pthreads implementation, which
indicated that this fallback was not currently compiling successfully
and applying this patch resolves that.

Patch by Andy Chien.

8744520b53 Removing the static initializer in ManagedStatic.cpp by using llvm_call_once to initialize the ManagedStatic mutex.
Summary:
This patch adds an llvm_call_once which is a wrapper around std::call_once on platforms where it is available and devoid of bugs. The patch also migrates the ManagedStatic mutex to be allocated using llvm_call_once.

These changes are philosophically equivalent to the changes added in r219638, which were reverted due to a hang on Win32 which was the result of a bug in the Windows implementation of std::call_once.

f0f98417ca Revert "r216914 - Revert: [APFloat] Fixed a bug in method 'fusedMultiplyAdd'"
Reapply r216913, a fix for PR20832 by Andrea Di Biagio. The commit was reverted
because of buildbot failures, and credit goes to Ulrich Weigand for isolating
the underlying issue (which can be confirmed by Valgrind, which does helpfully
light up like the fourth of July). Uli explained the problem with the original
patch as:

  It seems the problem is calling multiplySignificand with an addend of category
  fcZero; that is not expected by this routine.  Note that for fcZero, the
  significand parts are simply uninitialized, but the code in (or rather, called
  from) multiplySignificand will unconditionally access them -- in effect using
  uninitialized contents.

This version avoids using a category == fcZero addend within
multiplySignificand, which avoids this problem (the Valgrind output is also now
clean).

Original commit message:

[APFloat] Fixed a bug in method 'fusedMultiplyAdd'.

When folding a fused multiply-add builtin call, make sure that we propagate the
correct result in the case where the addend is zero, and the two other operands
are finite non-zero.

Example:
  define double @test() {
    %1 = call double @llvm.fma.f64(double 7.0, double 8.0, double 0.0)
    ret double %1
  }

Before this patch, the instruction simplifier wrongly folded the builtin call
in function @test to constant 'double 7.0'.
With this patch, method 'fusedMultiplyAdd' correctly evaluates the multiply and
propagates the expected result (i.e. 56.0).

Added test fold-builtin-fma.ll with the reproducible from PR20832 plus extra
test cases to verify the behavior of method 'fusedMultiplyAdd' in the presence
of NaN/Inf operands.

This fixes PR20832.

ee3948fdbe Use llvm-symbolizer to symbolize LLVM/Clang crash dumps.
This change modifies fatal signal handler used in LLVM tools.
Now it attempts to find llvm-symbolizer binary and communicates
with it in order to turn instruction addresses into
function/file/line info entries. This should significantly improve
stack traces readability in Debug builds.

This feature only works on selected platforms (including Darwin
and Linux). If the symbolization fails for some reason, signal
handler will fallback to the original behavior.

220c5ca8f4 Support: Don't call close again if we get EINTR
Most Unix-like operating systems guarantee that the file descriptor is
closed after a call to close(2), even if close comes back with EINTR.
For these systems, calling close _again_ will either do nothing or close
some other file descriptor open(2)'d by another thread. (Linux)

However, some operating systems do not have this behavior.  They require
at least another call to close(2) before guaranteeing that the
descriptor is closed. (HP-UX)

And some operating systems have an unpredictable blend of the two
behaviors! (xnu)

Avoid this disaster by blocking all signals before we call close(2).
This ensures that a signal will not be delivered to the thread and
close(2) will not give us back EINTR.  We restore the signal mask once
the operation is done.

N.B. This isn't a problem on Windows, it doesn't have a notion of EINTR
because signals always get delivered to dedicated signal handling
threads.

02474a32eb Move the complex address expression out of DIVariable and into an extra
argument of the llvm.dbg.declare/llvm.dbg.value intrinsics.

Previously, DIVariable was a variable-length field that has an optional
reference to a Metadata array consisting of a variable number of
complex address expressions. In the case of OpPiece expressions this is
wasting a lot of storage in IR, because when an aggregate type is, e.g.,
SROA'd into all of its n individual members, the IR will contain n copies
of the DIVariable, all alike, only differing in the complex address
reference at the end.

By making the complex address into an extra argument of the
dbg.value/dbg.declare intrinsics, all of the pieces can reference the
same variable and the complex address expressions can be uniqued across
the CU, too.
Down the road, this will allow us to move other flags, such as
"indirection" out of the DIVariable, too.

The new intrinsics look like this:
declare void @llvm.dbg.declare(metadata %storage, metadata %var, metadata %expr)
declare void @llvm.dbg.value(metadata %storage, i64 %offset, metadata %var, metadata %expr)

This patch adds a new LLVM-local tag to DIExpressions, so we can detect
and pretty-print DIExpression metadata nodes.

What this patch doesn't do:

This patch does not touch the "Indirect" field in DIVariable; but moving
that into the expression would be a natural next step.

af34c3a995 Fix llvm::huge_valf multiple initializations with Visual C++.
llvm::huge_valf is defined in a header file, so it is initialized
multiple times in every compiled unit upon program startup.

With non-VC compilers huge_valf is set to a HUGE_VALF which the
compiler can probably optimize out.

With VC numeric_limits<float>::infinity() does not return a number
but a runtime structure member which therotically may change 
between calls so the compiler does not optimize out the 
initialization and it happens many times. It can be easily seen by 
placing a breakpoint on the initialization line.

This patch moves llvm::huge_valf initialization to a source file
instead of the header.

e93da60ac4 [Support] Add type-safe alternative to llvm::format()
llvm::format() is somewhat unsafe. The compiler does not check that integer
parameter size matches the %x or %d size and it does not complain when a 
StringRef is passed for a %s.  And correctly using a StringRef with format() is  
ugly because you have to convert it to a std::string then call c_str().
 
The cases where llvm::format() is useful is controlling how numbers and
strings are printed, especially when you want fixed width output.  This
patch adds some new formatting functions to raw_streams to format numbers
and StringRefs in a type safe manner. Some examples:

   OS << format_hex(255, 6)        => "0x00ff"
   OS << format_hex(255, 4)        => "0xff"
   OS << format_decimal(0, 5)      => "    0"
   OS << format_decimal(255, 5)    => "  255"
   OS << right_justify(Str, 5)     => "  foo"
   OS << left_justify(Str, 5)      => "foo  "

66e6cd27a3 Windows/DynamicLibrary.inc: Remove 'extern "C"' in ELM_Callback.
'extern "C" static' is not accepted by g++-4.7. Rather to tweak, I just removed 'extern "C"', since it doesn't affect the ABI.

612d00a347 In this callback ModuleName includes the file path.
Comparing ModuleName to the file names listed will 
always fail. 

I wonder how this code ever worked and what its 
purpose was. Why exclude the msvc runtime DLLs
but not exclude all Windows system DLLs?

Anyhow, it does not function as intended.

clang-formatted as well.

0a277ea23d LineIterator: Provide a variant that keeps blank lines
It isn't always useful to skip blank lines, as evidenced by the
somewhat awkward use of line_iterator in llvm-cov. This adds a knob to
control whether or not to skip blanks.
