iterator-to-pointer conversion to an infinite for loop.  Now it's clear
that the condition doesn't terminate.

The only change in behaviour is if an invalid iterator (holding nullptr)
was passed into AMDGPUCFGStructurizer::reversePredicateSetter.  There
are only two callers, and they both dereference the iterator before
sending it in, so rather than adding an early return to avoid the loop
I've just asserted (using a static_cast, to avoid an implicit conversion
to pointer).

Stop using an implicit conversion from the return of
MachineBasicBlock::getFirstTerminator to MachineInstr*.  In two cases,
directly dereference to a MachineInstr& since later code assumes it's
valid.  In a third case, change to an iterator since later code checks
against MachineBasicBlock::end.

Although the fix for the third case avoids undefined behaviour, I expect
this doesn't cause a functionality change in practice (since the basic
block already has a terminator).

ARM: support high registers in __builtin_longjmp on WoA

Windows on ARM uses a pure thumb-2 environment.  This means that it can select a
high register when doing a __builtin_longjmp.  We would use a tLDRi which would
truncate the register to a low register.  Use a t2LDRi12 to get the full
register file access.  Tweak the code to just load into PC, as that is an
interworking branch on all supported cores anyways.

Peter Collingbourne [Thu, 7 Jul 2016 18:31:51 +0000 (18:31 +0000)]
ThinLTO: Do not take into account whether a definition has multiple copies when promoting.

We currently do not touch a symbol's linkage in the case where a definition
has a single copy. However, this code is effectively unnecessary: either
the definition is not exported, in which case the internalize phase sets
its linkage to internal, or it is exported, in which case we need to promote
linkage to weak. Those two cases are already handled by existing code.

I believe that the only real functional change here is in the case where we
have a single definition which does not prevail (e.g. because the definition
in a native object file prevails). In that case we now lower linkage to
available_externally following the existing code path for that case.

As a result we can remove the isExported function parameter from the
thinLTOResolveWeakForLinkerInIndex function.
