9c674bb012 An array of chars of length 8 will also cause the stack protector to be inserted 
into the function. Reflect that here so that the array will be placed next to
the SP.

81550dc0a8 Fix the issue that r143552 was trying to address the _right_ way. One-register lists are legal on LDM/STM instructions, but we should not print the PUSH/POP aliases when they appear. This fixes round tripping on this instruction.

05a484b909 Add back the top-level target for 'llvm-config' and the dependency edge 
to force it to build after all library targets so it has complete
dependency information. This should fix broken 'make install' with
CMake.

This is a partial revert of r143540, but it doesn't revert the most
important part of that change: removing the dependency edge from LLVM
tools to the llvm-config script.

d3714b60b5 Rewrite LinearFunctionTestReplace to handle pointer-type IVs.

combintions of modes (iv-rewrite/no-iv-rewrite) and IV types. This
second rewrite of the code attempts to deal with these cases systematically.

37efc9fe42 Begin collecting some of the statistics for block placement discussed on 
the mailing list. Suggestions for other statistics to collect would be
awesome. =]

Currently these are implemented as a separate pass guarded by a separate
flag. I'm not thrilled by that, but I wanted to be able to collect the
statistics for the old code placement as well as the new in order to
have a point of comparison. I'm planning on folding them into the single
pass if / when there is only one pass of interest.

1bfc9f8ff2 The TableGen parts of the CMake build are seriously broken. This fixes 
one aspect of them by having them use the (annoying, if not broken)
proper library dependency model for adding the LLVMTableGen library as
a dependency. This could manifest as a link order issue in the presence
of separate LLVM / Clang source builds with CMake and a linker that
really cares about such things.

Also, add the Support dependency to llvm-tblgen itself so that it
doesn't rely on TableGen's transitive Support dependency. A parallel
change for clang-tblgen will be forthcoming.

9af37a3de8 Add support to the linker to lazily link in functions. This change only links functions marked with specific linkage (internal, private, linker_private, linker_private_weak, linker_private_weak_def_auto, linkonce, linkonce_odr, and available_externally) if they have uses in the destination module. Instead of automatically linking, these functions are placed onto a worklist to be processed in the final stage of linking. We iterate over the list and if any functions on the list have uses in the destination module, we link them in and repeat the process until no changes in the state (uses) has changed. This means that any functions in the LazilyLink worklist that have a use in the destination module will be linked in and none that don't.

064e48a3dc Fixed a bug in the code to create a dwarf file and directory table entires when 
it is separating the directory part from the basename of the FileName.  Noticed 
that this:

  .file 1 "dir/foo"

when assembled got the two parts switched.  Using the Mac OS X dwarfdump tool
it can be seen easily:

% dwarfdump -a a.out
include_directories[  1] = 'foo'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 dir
...

Which should be:
...
include_directories[  1] = 'dir'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
