within the codegen EK_GPRel64BlockAddress. This was not 
supported for direct object output and resulted in an assertion.

This change adds support for EK_GPRel64BlockAddress for 
direct object.

One fallout from this is to turn on rela relocations 
for mips64 to match gas.

SelectionDAG's 'init' has not been called when the SelectionDAGBuilder is
constructed (in SelectionDAGISel's constructor), so this was previously always
initialized with 0.

Reduce alignment of SmallVector<T> to the required amount, rather than forcing 16-byte alignment. This fixes misaligned SmallVector accesses via ExtractValueInst's SmallVector data member.

strict weak ordering, and don't pass possibly-null pointers to dyn_cast.

llvm-svn: 162314

int64_t, Symbol64TableEntry is actually only stored with 4-byte alignment
within the file.

The usage of #pragma pack here is copied from the corresponding code in
Support/Endian.h, so shouldn't introduce any new portability problems.

llvm-svn: 162312

no cost to using memcpy here: the fixed code is optimized by LLVM to perfect
machine code.

According to http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
it's suggested that compile_commands.json in the root of the LLVM source tree
should be a symlink to the json file produced by your build system of choice.

So here's a patch so it doesn't turn up in git status, etc.

Thanks to Duncan Sands for catching this random file in code review.

Even looking at the revision history I couldn't quite piece together why this
cast was ever written in the first place, but I assume it was because of some
change in the inheritance, perhaps this function was reimplemented in a
derived type & this caller was meant to get the base version (& it wasn't
virtual)?

on a patch by Andy/PaX. I added the support for dot and dollar.

llvm-svn: 162298

this is the index of the operand that failed to match.

Note: This may cause a buildbot failure due to an API mismatch in clang.  Should
recover with my next commit to clang.

consistent with the other "expected identifier" errors.
Extracted from the Andy/PaX patch. I added the test.

The MCJIT doesn't need or want a TargetJITInfo. That's vestigal from the old
JIT, so just remove it.

number of bits was bigger than 32.  I checked every use of this function
that I could find and it looks like the maximum number of bits is 32, so I've
added an assertion checking this property, and a type cast to (hopefully) stop
PVS-Studio from warning about this in the future.

This optimization is really just replacing allocas wholesale with
globals, there is no scalarization.

The underlying motivation for this patch is to simplify the SROA pass
and focus it on splitting and promoting allocas.

The getSumForBlock function was quadratic in the number of successors
because getSuccWeight would perform a linear search for an already known
iterator.

This patch was originally committed as r161460, but reverted again
because of assertion failures. Now that duplicate Machine CFG edges have
been eliminated, this works properly.

llvm-svn: 162233

IR that hasn't been through SimplifyCFG can look like this:

  br i1 %b, label %r, label %r

Make sure we don't create duplicate Machine CFG edges in this case.

Fix the machine code verifier to accept conditional branches with a
single CFG edge.

llvm-svn: 162230

LLVM IR has labeled duplicate CFG edges, but since Machine CFG edges
don't have labels, it doesn't make sense to allow duplicates. There is
no way of telling what the edges mean.

Duplicate CFG edges cause confusion when dealing with edge weights. It
seems that code producing duplicate CFG edges usually does the wrong
thing with edge weights.
