13fd7205fa [OCaml] Initialize local roots prior to raising.
On 4.02, the OCaml unwinder otherwise gets confused and segfaults.

cf0fe98b05 [OCaml] Avoid embedding absolute paths into executables.
Bindings built out-of-tree, e.g. via OPAM, should append
a line to META.llvm like the following:

linkopts = "-cclib -L$libdir -cclib -Wl,-rpath,$libdir"

where $libdir is the lib/ directory where LLVM libraries are
installed.

95a8dca3db [OCaml] Run tests twice, with ocamlc and ocamlopt (if available)
ocamlc and ocamlopt expose a distinct set of buildsystem bugs, e.g.
only ocamlc would detect -custom or -dllib-related bugs, and as all
buildbots will have ocamlopt, these bugs will stay hidden.

This change should add no more than 30 seconds of testing time.

2b6bd7aaf5 Use ErrorOr for the ::create factory on instrumented and sample profilers.
Summary:
As discussed in
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20141027/242445.html,
the creation of reader and writer instances is better done using
ErrorOr. There are no functional changes, but several callers needed to
be adjusted.

2220408e1a Support REG_SEQUENCE in tablegen.
The problem is mostly that variadic output instruction
aren't handled, so it is rejected for having an inconsistent
number of operands, and then the right number of operands
isn't emitted.

eaa221a23e Re-commit r221056 and others with fix, "[mips] Move F128 argument handling into MipsCCState as we did for returns. NFC."
sret arguments can never originate from an f128 argument so we detect
sret arguments and push false into OriginalArgWasF128.

0a6665ead5 Revert r221096 bringing back r221014 with a fix.
The issue was that linkAppendingVarProto does the full linking job, including
deleting the old dst variable. The fix is just to call it and return early
if we have a GV with appending linkage.

original message:

    Refactor duplicated code in liking GlobalValues.

    There is quiet a bit of logic that is common to any GlobalValue but was
    duplicated for Functions, GlobalVariables and GlobalAliases.

    While at it, merge visibility even when comdats are used, fixing pr21415.

67177d320d Add DwarfUnit::isDwoUnit and use it to generalize string creation
Currently we only need to emit skeleton strings into the CU header and
we do this by explicitly calling "addLocalString". With gmlt-in-fission,
we'll be emitting a bunch of other strings from other codepaths where
it's not statically known that these strings will be local or not.

Introduce a virtual function to indicate whether this unit is a DWO unit
or not (I'm not sure if we have a good term for this, the
opposite/alternative to 'skeleton' unit) and use that to generalize the
string emission logic so that strings can be correctly emitted in both
the skeleton and dwo unit when in split dwarf mode.

And to demonstrate that this works, switch the existing special callers
of addLocalString in the skeleton builder to addString - and they still
work. Yay.

1fcc568ebb Remove the last mention of LineTablesOnly from DwarfUnit, sinking it into DwarfCompileUnit
This is a useful distinction/invariant/delination to make because
LineTablesOnly mode is never relevant to type units, so it's clear that
we're not doing weird line-tables-only-with-types by making this API
choice.

It also lays the foundations nicely for adding gmlt-like data to fission
skeleton CUs while limiting the effects to CUs and not TUs.

3ee898c624 Don't bother creating LabelBegin for .dwo units
This would help catch cases where we might otherwise try to reference a
dwo CU label, which would be weird - because without relocations in the
dwo file it's not generally meaningful to talk about the CU offsets
there (or, if it is, we can do so in absolute terms without using a
relocation to compute it).

79e72dd73c Docs: update va_arg example with valid x86_64 va_list type.
The given example was overflowing its alloca and segfaulting if actually run on
x86, so it's a good idea to provide something that works there too.

d998d1cc56 Drop DwarfCompileUnit::getLocalLabel* in favor of just mapping through the skeleton explicitly.
Confusing to do this two different ways - I'm not too wedded to either
one, but here goes.

This allows the CU label to be emitted only for compile units, as
they're the only ones that need it (so they can be referenced from
pubnames)

ed297abb0a InstCombine: Don't assume that m_ZExt matches an Instruction
m_ZExt might bind against a ConstantExpr instead of an Instruction.
Assuming this, using cast<Instruction>, results in InstCombine crashing.

Instead, introduce ZExtOperator to bridge both Instruction and
ConstantExpr ZExts.

This fixes PR21445.

8ff48760a3 Remove DwarfUnit::LabelEnd in favor of computing the length of the section directly
This was a compile-unit specific label (unused in type units) and seems
unnecessary anyway when we can more easily directly compute the size of
the compile unit.
