Duncan Sands 4581ddc123 Teach InstructionSimplify about phi nodes. I chose to have it simply
offload the work to hasConstantValue rather than do something more
complicated (such handling mutually recursive phis) because (1) it is
not clear it is worth it; and (2) if it is worth it, maybe such logic
would be better placed in hasConstantValue.  Adjust some GVN tests
which are now cleaned up much further (eg: all phi nodes are removed).

Chris Lattner 4e44cb8bcb this test is pretty pointless and "propogation" isn't a word (or so Misha claims).

Rafael Espindola 7d0ba3464e Handle a peculiar comdat case: Creating a section with an undefined
signature symbol causes a local symbol to be created unless there is
some other use of the symbol.

Duncan Sands 8c58ba4199 Testcase to go along with commit 118923 ("Have GVN simplify instructions
as it goes").  Before -std-compile-opts only got it down to
  %a = tail call i32 @foo(i32 0) readnone
  %x = tail call i32 @foo(i32 %a) readnone
  %y = tail call i32 @foo(i32 %a) readnone
  %z = icmp eq i32 %x, %y
  ret i1 %z
while now -basicaa -gvn alone reduce it to
  %a = call i32 @foo(i32 0) readnone
  %x = call i32 @foo(i32 %a) readnone
  ret i1 true

Duncan Sands 641baf1646 Generalize the reassociation transform in SimplifyCommutative (now renamed to
SimplifyAssociativeOrCommutative) "(A op C1) op C2" -> "A op (C1 op C2)",
which previously was only done if C1 and C2 were constants, to occur whenever
"C1 op C2" simplifies (a la InstructionSimplify).  Since the simplifying operand
combination can no longer be assumed to be the right-hand terms, consider all of
the possible permutations.  When compiling "gcc as one big file", transform 2
(i.e. using right-hand operands) fires about 4000 times but it has to be said
that most of the time the simplifying operands are both constants.  Transforms
3, 4 and 5 each fired once.  Transform 6, which is an existing transform that
I didn't change, never fired.  With this change, the testcase is now optimized
perfectly with one run of instcombine (previously it required instcombine +
reassociate + instcombine, and it may just have been luck that this worked).

Dale Johannesen bee283837f This test stops after disassembling 1 instructions on
darwin and, judging from the buildbots, Linux.
Removing it for now, but this is not the right fix,
Wesley please look at it.

Daniel Dunbar 9589bf8a86 lli: Switch to using ParseIRFile, for consistency with other LLVM tools.
- Also, switch tests to not using llvm-as. They run 20% faster now, not that it matters.

Evan Cheng 2d59ee34f1 Add some missing isel predicates on def : pat patterns to avoid generating VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next.

Kalle Raiskila 0a9dd405a5 Fix memory access lowering on SPU, adding
support for the case where alignment<value size.

These cases were silently miscompiled before this patch.
Now they are overly verbose -especially storing is- and
any front-end should still avoid misaligned memory 
accesses as much as possible. The bit juggling algorithm
added here probably has some room for improvement still.
