Fariborz Jahanian 5a866c0bf2 Ir-gen the side-effect(s) when __builtin_expect is 
constant-folded. // rdar://9330105

Bob Wilson ee674fb73d Workaround buildbot failure by hacking up this test to emit llvm IR. 
This is not a real fix.  It needs some checks to make sure the IR is correct.

John McCall e0fda7377e The 0.98 revision of the x86-64 ABI clarified a lot of things, some 
of which break strict compatibility with previous compilers.  Implement
one of them and then immediately opt out on Darwin.

Chris Lattner 97bbee2fb4 Fix a miscompilation I introduced in r129652, thanks for Eli for tracking 
it down.  we effectively were compile the testcase into:

void test14(int x) {
  switch (x) {
    case 11: break;
    case 42: test14(97);  // fallthrough
    default: test14(42); break;

which is not the same thing at all.  This fixes a miscompilation of 
MallocBench/gs seen on the clang-x86_64-linux-fnt buildbot.

Chris Lattner bc204c8043 implement rdar://9289524 - case followed immediately by break results in empty IR block, 
a -O0 code quality issue.

Chris Lattner 30107ed600 fold memcpy/set/move_chk to llvm.memcpy/set/move when the sizes 
are trivial.  This exposes opportunities earlier, and allows fastisel
to do good things with these at -O0.

This addresses rdar://9289468 - clang doesn't fold memset_chk at -O0

Chris Lattner 56784f9de6 fix rdar://9289603 - clang should fold trivial ?: for enums as well as integer constants into select at -O0 
by making the isCheapEnoughToEvaluateUnconditionally predicate handle anything that folds to a constant.  In particular, we now fold enums.

Anton Korobeynikov 231e875b5c Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or 
AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86.

In particular, all library functions should always be AAPCS regardless of floating point ABI used.

Daniel Dunbar 417bf0f147 IRgen: Improve GCC compatibility when dealing with packed arrays by propagating 
the array alignment to the array access.
 - This is more or less the best we can do without having alignment present in
   the type system, but is a long way from truly matching how GCC handles this.

Douglas Gregor 1baf38f5a6 On Mac OS X, the presence of an 'availability' attribute for that 
platform implies default visibility. To achieve these, refactor our
lookup of explicit visibility so that we search for both an explicit
VisibilityAttr and an appropriate AvailabilityAttr, favoring the
VisibilityAttr if it is present.

Bill Wendling ec9d2633f1 When we adjust the inline ASM type, we need to take into account an early 
clobber with the 'y' constraint. Otherwise, we get the wrong return type and an
assert, because it created a '<1 x i64>' vector type instead of the x86_mmx
type.
