Edwin Vane 2032fb973b Don't include outer-most explicit cast in nullptr replacement
The outer-most explicit cast is now left alone by the Use-Nullptr transform to
maintain the type of the expression and avoid introducing ambiguities.

Fixes PR15395.

Arnold Schwaighofer 9d7a3827e4 ARM cost model: Fix costs for some vector selects
I was too pessimistic in r177105. Vector selects that fit into a legal register
type lower just fine. I was mislead by the code fragment that I was using. The
stores/loads that I saw in those cases came from lowering the conditional off
an address.

Changing the code fragment to:

%T0_3 = type <8 x i18>
%T1_3 = type <8 x i1>

define void @func_blend3(%T0_3* %loadaddr, %T0_3* %loadaddr2,
                         %T1_3* %blend, %T0_3* %storeaddr) {
  %v0 = load %T0_3* %loadaddr
  %v1 = load %T0_3* %loadaddr2
==> FROM:
  ;%c = load %T1_3* %blend
==> TO:
  %c = icmp slt %T0_3 %v0, %v1
==> USE:
  %r = select %T1_3 %c, %T0_3 %v0, %T0_3 %v1

  store %T0_3 %r, %T0_3* %storeaddr
  ret void
}

revealed this mistake.

Edwin Vane 52c326ec78 Prevent nullptr_t-typed exprs from being replaced
The Use-Nullptr transform was replacing nullptr_t-typed expressions because in

Adrian Prantl 5acf8a3ac5 Force column info only for direct inlined functions. This should strike
the balance between expected behavior and compatibility with the gdb
testsuite.
(GDB gets confused if we break an expression into multiple debug
stmts so we enable this behavior only for inlined functions. For the
full experience people can still use -gcolumn-info.)

Hal Finkel 8d7fbc9dad Enable unaligned memory access on PPC for scalar types
Unaligned access is supported on PPC for non-vector types, and is generally
more efficient than manually expanding the loads and stores.

A few of the existing test cases were using expanded unaligned loads and stores
to test other features (like load/store with update), and for these test cases,
unaligned access remains disabled.

Nico Weber 966b331251 Remove a pointless assertion.
FindNodeOrInsertPos() is called 10 lines earlier already, and the function
early-returns there if the result is != 0. InsertPos isn't recomputed after
that check, so this assert is always trivially true. (And it has nothing to
do with if T is canonical or not.)

Hal Finkel b0fac42987 Protect PPC Altivec patterns with a predicate
In preparation for the addition of other SIMD ISA extensions (such as QPX) we
need to make sure that all Altivec patterns are properly predicated on having
Altivec support.

No functionality change intended (one test case needed to be updated b/c it
assumed that Altivec intrinsics would be supported without enabling Altivec
support).

Rafael Espindola ef9d3494b2 Fix the FDE encoding to be relative on ELF.
This is a very late complement to r130637 which fixed this on x86_64. Fixes
pr15448.

Since it looks like that every elf architecture uses this encoding when using
cfi, make it the default for elf. Just exclude mips64el. It has a lovely
.ll -> .o test (ef_frame.ll) that tests that nothing changes in the binary
content of the .eh_frame produced by llc. Oblige it.

Hal Finkel bb420f10e9 Allocate the RS spill slot for any PPC function with spills and a large stack frame
For spills into a large stack frame, the FI-elimination code uses the register
scavenger to obtain a free GPR for use with an r+r-addressed load or store.
When there are no available GPRs, the scavenger gets one by using its spill
slot. Previously, we were not always allocating that spill slot and the RS
would assert when the spill slot was needed.

I don't currently have a small test that triggered the assert, but I've
created a small regression test that verifies that the spill slot is now
added when the stack frame is sufficiently large.
