The finalizeObject method calls generateCodeForModule on each of the currently
'added' objects, but generateCodeForModule moves objects out of the 'added'
set as it's called. To avoid iterator invalidation issues, the added set is
copied out before any calls to generateCodeForModule.
This should fix http://llvm.org/PR20851 .

computation was totally wrong, but somehow it didn't really show up with
llc.
I've added an assert that triggers on multiple existing test cases and
updated one of them to show the correct value.
There appear to still be more bugs lurking around insertps's mask. =/
However, note that this only really impacts the new vector shuffle
lowering.

Previously llc would hit an llvm_unreachable when compiling an inline-asm
instruction with malformed constraint string "~x{21}". This commit enables
LLParser to catch the error earlier and print a more helpful diagnostic.

When linking llvm.global_ctors with the optional third element we have to handle

Summary:
Until r216870 LLVMCreateObjectFile returned nullptr in case of an error,
so callers could check if the call was successful. Now, it always
returns an OwningBinary wrapped as an LLVMObjectFileRef, so callers
can't check if the call was successul.
This results in a segfault running e.g.
llvm-c-test --object-list-sections < /dev/null
So the old behaviour should be restored.

This reverts commit r217211.
Both the bfd ld and gold outputs were valid. They were using a Rela relocation,
so the value present in the relocated location was not used, which caused me
to misread the output.

Fixes PR20523.
When spilling variables onto the stack, spillVirtReg() is setting the
parent pointer of the cloned DBG_VALUE intrinsic for the stack location
to the parent pointer of the original intrinsic. MachineInstr parent
pointers should however always point to the parent basic block.
MBB is shadowing the MBB member variable. The instruction still ends up
being inserted into the right basic block, because it's inserted after MI
which serves as the iterator.
I failed at constructing a reliable testcase for this, see
http://llvm.org/bugs/show_bug.cgi?id=20523 for a large testcases.

The header contains an offset to the DWARF line table for the CU. The offset
must be section relative for COFF and absolute for others. The non-assembly
code path for the DWARF header generation already has the correct emission for
the headers. This corrects the assembly input path.
This was identified by BFD objecting to the LLVM generated DWARF information.

Patched by Sergey Dmitrouk.
This pass tries to make consecutive compares of values use same operands to
allow CSE pass to remove duplicated instructions. For this it analyzes
branches and adjusts comparisons with immediate values by converting:
GE -> GT
GT -> GE
LT -> LE
LE -> LT
and adjusting immediate values appropriately. It basically corrects two
immediate values towards each other to make them equal.
