7a9bb4d47f Expand relocation type field to 64 bits. MachO scattered relocations require 33 bits of type info.

69d98376b9 Add support for the notion of "hidden" relocations. On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves. 
I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden.

c551c1c5f9 Add support for a new extension to the .file directive: 
.file filenumber "directory" "filename"

This removes one join+split of the directory+filename in MC internals. Because
bitcode files have independent fields for directory and filenames in debug info,
this patch may change the .o files written by existing .bc files.

321335142c Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance 
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

de2d3cf093 use 64-bit types instead of off_t/size_t to avoid the issue when 
gold plugin is built with Large File Support (sizeof(off_t) == 64 on i686)

(sizeof(off_t) == 32 on i686) which corrupts the stack.

- Add enum SymbolType and function getSymbolType()
- Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions.
- Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address.
- Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

c4e7a56915 Sketch out a DWARF parser. 
This introduces a new library to LLVM: libDebugInfo. It will provide debug information

It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an
object file. It can be used to write tests for DWARF input and output easily.

26d5603f54 llvm-objdump: Use help of CFG to print assembly when --cfg is passed. 
This way we can avoid printing unreachable code (data).

fdea9930ac Remove the LowerSetJmp pass. It wasn't used effectively by any of the targets. 
This is some of my original LLVM code. *wipes tear*

73efcf56f6 move PassManagerBuilder.h to IPO. This is a non intuitive place to put it, 
but it solves a layering violation since things in Support are not supposed to
use things in Transforms.

f7890e34b9 Rewrite the CMake build to use explicit dependencies between libraries, 
specified in the same file that the library itself is created. This is
more idiomatic for CMake builds, and also allows us to correctly specify
dependencies that are missed due to bugs in the GenLibDeps perl script,
or change from compiler to compiler. On Linux, this returns CMake to
a place where it can relably rebuild several targets of LLVM.

I have tried not to change the dependencies from the ones in the current
auto-generated file. The only places I've really diverged are in places
where I was seeing link failures, and added a dependency. The goal of
this patch is not to start changing the dependencies, merely to move
them into the correct location, and an explicit form that we can control
and change when necessary.

This also removes a serialization point in the build because we don't
have to scan all the libraries before we begin building various tools.
We no longer have a step of the build that regenerates a file inside the
source tree. A few other associated cleanups fall out of this.

This isn't really finished yet though. After talking to dgregor he urged
switching to a single CMake macro to construct libraries with both
sources and dependencies in the arguments. Migrating from the two macros
to that style will be a follow-up patch.

Also, llvm-config is still generated with GenLibDeps.pl, which means it
still has slightly buggy dependencies. The internal CMake
'llvm-config-like' macro uses the correct explicitly specified
dependencies however. A future patch will switch llvm-config generation
(when using CMake) to be based on these deps as well.

This may well break Windows. I'm getting a machine set up now to dig
into any failures there. If anyone can chime in with problems they see
or ideas of how to solve them for Windows, much appreciated.
