We rely on it when doing the transforms. This can happen when there is an
indirectbr in  the loop.

Fixes PR13892.

Make the 'get*AlignmentFromAttr' functions into member functions within the Attributes class. Now with fix.

llvm-svn: 164370

We inserted a placeholder that was never replaced because the function was
already visited. Assert that all placeholders have been resolved when tearing
down the bitcode reader.

Fixes PR13895.

Fix SymbolRef::getAddress implementation for ELF. The 'value' field in symbol table entry should be treated differently for relocatable and relocated files. This patch fixes symbol addresses printed by llvm-nm for executables and shared objects.

Quick review against the manual revealed a few obvious mistakes.

- Fix PR5145 and turn on test 8-bit atomic ops

llvm-svn: 164358

- Rewirte most atomic instructions in templates for both better
  maintenance and future extensions, such as HLE in TSX.

llvm/test/CodeGen/ARM/fast-isel.ll: Fix possible typos, s/@unaligned_i16_store/@unaligned_i16_load/g.

I guess this had apparently passed in +Asserts possibly due to verborsity.

The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

A PHI can't create interference on its own. If two live ranges interfere
at a PHI, they must also interfere when leaving one of the PHI
predecessors.

llvm-svn: 164330

The old-fashioned many-to-one value mapping doesn't always work when
merging vector lanes. A value can map to multiple different values, and
it can even be necessary to insert new PHIs.

When a value number is defined by a copy from a value number that
required SSa update, include the live range of the copied value number
in the SSA update as well. It is not necessarily a copy of the original
value number any longer.

We already have HoistThenElseCodeToIf, this patch implements
SinkThenElseCodeToEnd. When END block has only two predecessors and each
predecessor terminates with unconditional branches, we compare instructions in
IF and ELSE blocks backwards and check whether we can sink the common
instructions down.
