f9c9d1b4d0 capitalize project name, reference bugzilla
And fix the double-[]. It was including the [] as part of
the project name somehow, resulting in PACKAGE_TARNAME "-llvm-"
and a strange docdir default:

  --docdir=DIR           documentation root [DATAROOTDIR/doc/-llvm-]

d9a793d332 Add an optional separate install prefix for internal components. rdar://10217046
Some files installed by clang are not relevant for general users and we'd like
to be able to install them to a different location.  This adds a new
--with-internal-prefix configure option and a corresponding PROJ_internal_prefix
makefile variable, which defaults to the standard prefix.  A tool makefile
can specify that it should be installed to this internal prefix by defining
INTERNAL_TOOL.

9751c17d0d rename ENABLE_THREADS to LLVM_ENABLE_THREADS
Now that it needs to be exported in a public header (Valgrind.h)
it should be prefixed to avoid collision with other projects.
Add it to llvm-config.h as well.

This'll require regenerating the configure script after this
commit, but I don't have the required autoconf version.

381ec749e0 Move the AC_PROG_CC checks earlier in the configure file. The lateness
of the original check meant that configure was caching the default
CC check and using that instead of the result of AC_PROG_CC in both
configure checks and during compilation.

This wasn't affecting C++ so it was hard to notice.

Regenerate configure.

b2cd1f27c1 Update config.sub, config.guess and configure.
The motivation to do that:

1. Now, llvm would use the stock config.sub. Before that we had an
uncommitted FreeBSD-related patch. Now, it has been upstreamed and
comes back. It means that it would be easier to update these files in
the next time (less magic knowledge)

2. Fix a typo for pseudo-CPUs: 32e[lb] -> [lb]e32, 64e[lb]->[lb]64.
One of these CPUs is used for PNaCl and it was not really convenient
to have a CPU that starts with a digit.

311fcc9b92 Add NativeClient operating system support.
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

0b6c512312 Update autoconfig/config.{sub,guess} to the latest version
from the GNU upstream: git://git.savannah.gnu.org/config.git

1. It eliminates a local LLVM patch for auroraux (because, the
mainline config.sub has already got support of auroraux)
2. It adds several new recognized target cpus and operating systems
(in particular, PNaCl)

00f50519b6 Add new configure option, --disable-timestamps, intended to turn off anything which would mess up binary/object comparisons. Currently:
- Disables 'Built on ...' in 'foo --version'.
 - Disables timestamps from being embedded into .dir files.

6b8861e9f6 Overhauled llvm/clang docs builds. Closes PR6613.
NOTE: 2nd part changeset for cfe trunk to follow.

*** PRE-PATCH ISSUES ADDRESSED

- clang api docs fail build from objdir
- clang/llvm api docs collide in install PREFIX/
- clang/llvm main docs collide in install
- clang/llvm main docs have full of hard coded destination
  assumptions and make use of absolute root in static html files;
  namely CommandGuide tools hard codes a website destination
  for cross references and some html cross references assume
  website root paths

*** IMPROVEMENTS

- bumped Doxygen from 1.4.x -> 1.6.3
- splits llvm/clang docs into 'main' and 'api' (doxygen) build trees
- provide consistent, reliable doc builds for both main+api docs
- support buid vs. install vs. website intentions
- support objdir builds
- document targets with 'make help'
- correct clean and uninstall operations
- use recursive dir delete only where absolutely necessary
- added call function fn.RMRF which safeguards against botched 'rm -rf';
  if any target (or any variable is evaluated) which attempts
  to remove any dirs which match a hard-coded 'safelist', a verbose
  error will be printed and make will error-stop.

f4f4ce1e3c Default OPTIMIZE_OPTION to -O2 on FreeBSD, at the request of the Clang/FreeBSD
folks. LLVM/Clang is miscompiled by the standard GCC at -O3.

b533fafb38 Fix an autoconf bug: The second argument to AC_LANG_PROGRAM is code that
gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail, 
leaving their options disabled.

This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.

This also includes a regenerated configure, as the diff is small and telling.
