5fc1e951f6 make -filetype=obj default to emitting its output to foo.obj 
when on windows instead of foo.o.  Patch by Nathan Jeffords!

7edf493591 Fixed a sign-extension bug in the X86 disassembler 
that was causing PC-relative branch targets to be
evaluated incorrectly.  Also added support for
checking operand values to the llvm-mc tester.

153ad3b903 Remove the -enable-sjlj-eh option, which doesn't do anything. 
Remove the -enable-eh option which is only used by the JIT,
and replace it with -jit-enable-eh.

8a16d236db r98363 deleted a '!' when cleaning up whitespace. This caused globals which are 
*not* declarations to *not* be placed in the "preserve" list.

6a038be777 introduce a new CallGraphSCC class, and pass it around 
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,

bfbdc27d54 Generalize the EXPORTED_SYMBOL_FILE concept in the Makefiles to work with 
native linking export files, including running sed to prepend underscores
on darwin, and make use of it in libLTO and libEnhancedDisassembly.

Remove the leading underscores from library export files so that they
work with the new EXPORTED_SYMBOL_FILE support.

a672ffc669 Unbreak CMake build by improving the EnhancedDisassembly makefile a 
bit (we're not trying to build a shared library yet) and generating
the X86GenEDInfo.inc and ARMGenEDInfo.inc files as necessary.

29a7152676 Fixed a nasty layering violation in the edis source 
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

5066bc60be Build system fix to make llvm-mc properly build 
after edis.  Really, there ought to be some
mechanism to ensure that PARALLEL_DIRS get built
after DIRS.

7d250f2b65 Build system fixes. llvm-mc depends on 
libEnhancedDisassembly, so we now build the
static library in all cases (although the shared
library is only built when requested/possible).

Also, fixed a bug where edis wasn't properly
initializing the targets it uses.

033fde84b5 Second try at integrating the edis tester. This 
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

736f3ecc4c Bugfixes for edis. Code to initialize instruction 
state was being executed too lazily, and the LLVM
assembly syntax for the disassembler was not being
written into the proper disassembler state variable.

dcd7a375dd Added support for ARM disassembly to edis. 
I also added a rule to the ARM target's Makefile to
build the ARM-specific instruction information table
for the enhanced disassembler.

I will add the test harness for all this stuff in
a separate commit.

5b4c7591ac 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
$ 

don't stop at inc!

c2f273b52d Add special case bitcode support for DebugLoc. This avoids 
having the bitcode writer materialize mdnodes for all the
debug location tuples when writing out the bc file and 
stores the information in a more compact form.  For example,
the -O0 -g bc file for combine.c in 176.gcc shrinks from
739392 to 512096 bytes.

This concludes my planned short-term debug info work.
