Hal Finkel c20a08d25b Add PPC FP rounding instructions fri[mnpz]
These instructions are available on the P5x (and later) and on the A2. They
implement the standard floating-point rounding operations (floor, trunc, etc.).
One caveat: frin (round to nearest) does not implement "ties to even", and so
is only enabled in fast-math mode.

“process attach” should ask the same questions as process launch if there is a current process.
“process connect” then “process launch” or “process attach” should actually work.

Greg Clayton 3faf47c462 <rdar://problem/11730263>
PC relative loads are missing disassembly comments when disassembled in a live process.

This issue was because some sections, like __TEXT and __DATA in libobjc.A.dylib, were being moved when they were put into the dyld shared cache. This could also affect any other system that slides sections individually.

The solution is to keep track of wether the bytes we will disassemble are from an executable file (file address), or from a live process (load address). We now do the right thing based off of this input in all cases.

Michael Liao 5fff5c7b26 Enhance boolean simplification to handle 16-/64-bit RDRAND
- RDRAND always clears the destination value when a random value is not
  available (i.e. CF == 0). This value is truncated or zero-extended as
  the false boolean value to be returned. Boolean simplification needs
  to skip this 'zext' or 'trunc' node.

Anna Zaks 333481b90b [analyzer] Add support for escape of const pointers and use it to allow “newed” pointers to escape
Add a new callback that notifies checkers when a const pointer escapes. Currently, this only works
for const pointers passed as a top level parameter into a function. We need to differentiate the const
pointers escape from regular escape since the content pointed by const pointer will not change;
if it’s a file handle, a file cannot be closed; but delete is allowed on const pointers.

This should suppress several false positives reported by the NewDelete checker on llvm codebase.

Anna Zaks 05fb371efc [analyzer] Apply the suppression rules to the nil receiver only if the value participates in the computation of the nil we warn about.
We should only suppress a bug report if the IDCed or null returned nil value is directly related to the value we are warning about. This was
not the case for nil receivers - we would suppress a bug report that had an IDCed nil receiver on the path regardless of how it’s
related to the warning.

1) Thread EnableNullFPSuppression parameter through the visitors to differentiate between tracking the value which
is directly responsible for the bug and other values that visitors are tracking (ex: general tracking of nil receivers).
2) in trackNullOrUndef specifically address the case when a value of the message send is nil due to the receiver being nil.

Michael Liao 96b42608ab Skip moving call address loading into callseq when targets prefer register indirect call.
To enable a load of a call address to be folded with that call, this
load is moved from outside of callseq into callseq. Such a moving
adds a non-glued node (that load) into a glued sequence. This non-glue
load is only removed when DAG selection folds them into a memory form
call instruction. When such instruction selection is disabled, it breaks
DAG schedule.

To prevent that, such moving is disabled when target favors register
indirect call.

Previous workaround disabling CALL32m/CALL64m insn selection is removed.

Chad Rosier dbac025d84 [fast-isel] Add a preemptive fix for the case where we fail to materialize an
immediate in a register.  I don't believe this should ever fail, but I see no
harm in trying to make this code bullet proof.

I've added an assert to ensure my assumtion is correct.  If the assertion fires
something is wrong and we should fix it, rather then just silently fall back to
SelectionDAG isel.
