test/Transforms/SimplifyLibCalls/SPrintF.ll: Suppress this for now. r168677 unveiled another failure.

FYI, this test makes no sense with "not grep"... I saw "assertion failure" in stderr.

If the Src and Dst are the same instruction,
no loop-independent dependence is possible,
so we force the PossiblyLoopIndependent flag to false.

The test case results are updated appropriately.

This patch migrates the sprintf optimizations from the simplify-libcalls
pass into the instcombine library call simplifier.

open("/dev/fd/1-foobar") fails with EEXIST on cygwin.

ELF ABI.

Complex values are to be passed in registers as though the real and
imaginary parts were passed as separate parameters.  Prior to this
patch, complex values were passed as byval aggregates.  It turns out
that specifying getDirect() for all complex types when classifying the
argument type results in the desired behavior.

The new Clang test case verifies that the correct LLVM IR is generated
for caller and callee for each of the underlying types for _Complex.

Allow the expression parser to see more than just data symbols. We now accept any symbol that has an address. We take precautions to only accept symbols by their mangled or demangled names only if the demangled name was not synthesized. If the demangled name is synthesized, then we now mark symbols accordingly and only compare against the mangled original name.

The skipOnLinux decorator wasn't calling the test method correctly (no need to pass in the "self") resulting
in errors on MacOS X for the tests so decorated.

fewer issues.

Applied the patch, rather than committing it.

Detect the new fixed clang that properly supports bitfields in objc classes.

Revert r168635 "Step towards implementation of pass manager with doInitialization and doFinalization per module detangled from runOn?? calls, still has temporary code not to break ASAN to be removed when that pass conforms to the proposed model".
It appears to have broken at least one buildbot.

Added in first optimization using fast-math flags to serve as an example for following optimizations. SimplifyInstruction will now try to optimize an fmul observing its FastMathFlags to see if it can fold multiply by zero when 'nnan' and 'nsz' flags are set.

llvm-svn: 168648

llvm-svn: 168647

Added in bitcode enum for the serializing of fast-math flags. Added in the reading/writing of fast-math flags from the OptimizationFlags record for BinaryOps.

llvm-svn: 168646

Added in the ability to read LLVM IR text that contains fast-math flags as a sequence of capital letters separated by spaces in any order. Added in the printing of the fast-math flags in a canonical order, and don't print the other flags when 'fast' is specified, as 'fast' implies all the others.

Add in getter/setter methods for Instructions, allowing them to be the interface to FPMathOperator similarly to now NUS/NSW is handled.

llvm-svn: 168642

Created FastMathFlags convenience struct for the getting and setting of fast-math flags en masse. Added SubclassOptionalData bitfields and corresponding getters/setters to FPMathOperator for the various fast-math flags.
