Jakob Stoklund Olesen 2ae30e864d Avoid overflowing a signed integer which triggers undefined behaviour. 
Overflowing an unsigned integer is fine and behaves as you would expect.
Also fix a pasto, allowing SignExtend64 to take a 64-bit argument.

Zhongxing Xu 0f290ec0f0 Fix PR 6725. It looks like the copy constructor gets elided during inlining.

Chris Lattner 3b21e4d404 Give AsmParser an option to control whether it finalizes 
the stream.  New demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax
000000000000000b	movl	%eax,(%rsp)
000000000000000e	movl	%eax,0x04(%rsp)
0000000000000012	addq	$0x08,%rsp
0000000000000016	ret

Chris Lattner 8900ef1931 add .o file writing for inline asm in llc. Here's a silly 
demo:

$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
<inline asm>:1:2: error: unrecognized instruction
	abc incl    %eax
	^
LLVM ERROR: Error parsing inline asm

Only problem seems to be that the parser finalizes OutStreamer 
at the end of the first inline asm, which isn't what we want.
For example:

$ cat asm.c
int foo(int X) {
 __asm__ ("incl    %0" : "+r" (X));
 return X;
}
$ clang asm.c -S -o - -emit-llvm | llc
...
	subq	$8, %rsp
	movl	%edi, (%rsp)
	movl	%edi, %eax
	## InlineAsm Start
	incl    %eax
	## InlineAsm End
	movl	%eax, (%rsp)
	movl	%eax, 4(%rsp)
	addq	$8, %rsp
	ret
$ clang asm.c -S -o - -emit-llvm | llc -filetype=obj -o t.o
$ otool -tv t.o
t.o:
(__TEXT,__text) section
_foo:
0000000000000000	subq	$0x08,%rsp
0000000000000004	movl	%edi,(%rsp)
0000000000000007	movl	%edi,%eax
0000000000000009	incl	%eax
$

Chris Lattner adca608281 fix a really nasty bug that Evan was tracking in SCCP. When resolving 
undefs in branches/switches, we have two cases: a branch on a literal
undef or a branch on a symbolic value which is undef.  If we have a
literal undef, the code was correct: forcing it to a constant is the
right thing to do.

If we have a branch on a symbolic value that is undef, we should force
the symbolic value to a constant, which then makes the successor block
live.  Forcing the condition of the branch to being a constant isn't 
safe if later paths become live and the value becomes overdefined.  This
is the case that 'forcedconstant' is designed to handle, so just use it.

This fixes rdar://7765019 but there is no good testcase for this, the
one I have is too insane to be useful in the future.

Daniel Dunbar dc406b8e92 IRgen: Move BitField LValues to just hold a reference to the CGBitFieldInfo. 
- Unfortunately, this requires some horrible code in CGObjCMac which always
   allocats a CGBitFieldInfo because we don't currently build a proper layout
   for Objective-C classes. It needs to be cleaned up, but I don't want the
   bit-field cleanups to be blocked on that.

Douglas Gregor cf04b02d1d Extend the type printing policy to allow one to turn off the printing 
of file locations for anonymous tag types (e.g., "enum <anonymous at
t.h:15:6>"), which can get rather long.

Douglas Gregor d03e823fb4 Clarify the ownership semantics of the Diagnostic object used by 
ASTUnit. Previously, we would end up with use-after-free errors
because the Diagnostic object would be creating in one place (say,
CIndex) and its ownership would not be transferred into the
ASTUnit. Fixes <rdar://problem/7818608>.

Douglas Gregor 41e692dcf1 Introduce MaybeOwningPtr, a smart pointer that may (or may not) have 
ownership over the pointer it contains. Useful when we want to
communicate ownership while still having several clients holding on to
the same pointer *without* introducing reference counting.
