- JALR64 is not needed since N64 does not emit jal. 
- Add template parameter to BranchLink that sets the rt field. 
- Fix the set of temporary registers for O32 and N64.

Stub out the Sema interface for lambda expressions, and change the parser to use it.  Unconditionally error on lambda expressions because they don't work in any meaningful way yet.

(x > y) ? x : y
=>
(x >= y) ? x : y

So for something like
(x - y) > 0 : (x - y) ? 0
It will be
(x - y) >= 0 : (x - y) ? 0

This makes is possible to test sign-bit and eliminate a comparison against
zero. e.g.
subl   %esi, %edi
testl  %edi, %edi
movl   $0, %eax
cmovgl %edi, %eax
=>
xorl   %eax, %eax
subl   %esi, $edi
cmovsl %eax, %edi

Get rid of an unnecessary check; the AST for init-lists is the same independent of whether we're in C++11 mode.

llvm-svn: 147503

Before we'd get:

$ clang t.c 
fatal error: error in backend: Invalid operand for inline asm constraint 'i'!

Now we get:

$ clang t.c
t.c:16:5: error: invalid operand for inline asm constraint 'i'!
    "movq         (%4), %%mm0\n"
    ^

Which at least gets us the inline asm that is the problem.

Enhance UnixAPIChecker to also warn about zero-sized allocations to calloc() and realloc().  Patch by Cyril Roelandt!

llvm-svn: 147500

Minor tweak to name lookup for C/Objective-C: after the first name, still consider whether this is a redeclaration lookup when determining whether to look for the visible declaration

llvm-svn: 147499

the AST reader doesn't actually perform a merge, because name lookup
knows how to merge identical typedefs together.

As part of this, teach C/Objective-C name lookup to return multiple
results in all cases, rather than first digging through the attributes
to see if the value is overloadable. This way, we'll catch ambiguous
lookups in C/Objective-C.

Initialise constant Objective-C string isa pointers with a weak reference to the class, so that they are usable in +load methods if the string class has been compiled with clang - if it's been compiled with GCC, the ABI makes this impossible.  (GNU runtimes)

that if two modules A and B both contain a declaration of a tag such
as

and those two modules are unrelated, the two declarations of X will be
merged into a single redeclaration chain.

This patch caused a miscompilation of oggenc because a frame pointer was
suddenly needed halfway through register allocation.

This can only happen if the set of reserved registers changes during
register allocation.
