This time the warning found an actual bug, we don't want to handle
force_align_arg_pointer differently than __force_align_arg_pointer__.

InstCombine was incorrectly considering the conversion of the constant
zero to be unsafe.

We want to transform:
define float @bar(float %x) nounwind readnone optsize ssp {
  %conv = fpext float %x to double
  %cmp = fcmp olt double %conv, 0.000000e+00
  %conv1 = zext i1 %cmp to i32
  %conv2 = sitofp i32 %conv1 to float
  ret float %conv2
}

Into:
define float @bar(float %x) nounwind readnone optsize ssp {
  %cmp = fcmp olt float %x, 0.000000e+00   ; <---- This
  %conv1 = zext i1 %cmp to i32
  %conv2 = sitofp i32 %conv1 to float
  ret float %conv2
}

This matches clang, so default options in llc and friends are now closer to
clang's defaults.

Remove an assert that was expecting only the relevant 16bit portion for
the fixup being handled. Also kill some dead code in the T2 portion.

Also take this opportunity to clean up the rounding mode pass.

Remove the conditional that avoided passing the Objective-C runtime specification flags to cc1.  This fixes PR10369 (__builtin_NSStringMakeConstantString() selecting the wrong runtime in C / C++ code and crashing, although it doesn't fix the problem that instantiating the Mac runtime for non-Darwin targets was crashing.)

catch or repeated filter clauses.  Teach instcombine a bunch
of tricks for simplifying landingpad clauses.  Currently the
code only recognizes the GNU C++ and Ada personality functions,
but that doesn't stop it doing a bunch of "generic" transforms
which are hopefully fine for any real-world personality function.
If these "generic" transforms turn out not to be generic, they
can always be conditioned on the personality function.  Probably
someone should add the ObjC++ personality function.  I didn't as
I don't know anything about it.

us to manually provide Pat<> definitions for all FP instruction patterns.

This helps with porting code from 2.9 to 3.0 as TargetSelect.h changed location,
and if you include the old one by accident you will trigger this assert.

Fix a bug in the token caching for inline constructors in C++11, and improve error recovery in both dialects. This should fix the GCC test suite failures as well.

llvm-svn: 140847

CoreFoundation object-transfer properties audited, and add a #pragma
to cause them to be automatically applied to functions in a particular
span of code.  This has to be implemented largely in the preprocessor
because of the requirement that the region be entirely contained in
a single file;  that's hard to impose from the parser without registering
for a ton of callbacks.
