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.

use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

variable TARGET_HAS_DYNAMIC_LIBS

We need this so can not bake DESTDIR into the O'Caml symlinks.

the examples shared to make sure the shared library keeps working.

llvm-svn: 96959

Comes in two parts:
 1. Use --with-clang=path/to/clang/compiler to select an installed clang, or
    --with-built-clang to have the makefiles use the clang which will be built
    as the LLVM capable compiler. If neither is given, --with-built-clang will
    be used if the Clang sources are checked out into the standard location
    (tools/clang).

 2. Use --with-llvmcc={llvm-gcc,clang,none} to specify which LLVM capable
    compiler to use. If not given, then llvm-gcc will be used if available,
    otherwise Clang.

Makefile support still to come.

Eric, Doug, Chris, seem reasonable?

--enable-shared configure flag to have the tools linked shared. (2.7svn is just
$(LLVMVersion) so it'll change to "2.7" in the release.)  Always link the
example programs shared to test that the shared library keeps working.

On my mac laptop, Debug libLLVM2.7svn.dylib is 39MB, and opt (for example) is
16M static vs 440K shared.

Two things are less than ideal here:
1) The library doesn't include any version information. Since we expect to break
the ABI with every release, this shouldn't be much of a problem. If we do
release a compatible 2.7.1, we may be able to hack its library to work with
binaries compiled against 2.7.0, or we can just ask them to recompile. I'm
hoping to get a real packaging expert to look at this for the 2.8 release.
2) llvm-config doesn't yet have an option to print link options for the shared
library. I'll add this as a subsequent patch.

--build=triple and other configure options are passed
to the BuildTools/ sub-invocation more consistently

llvm-svn: 80854

try to use i686-darwin to build for arm-eabi, you'll quickly run into
several false assumptions that the target OS must be the same as the
host OS. These patches split $(OS) into $(HOST_OS) and $(TARGET_OS) to
help builds like "make check" and the test-suite able to cross
compile. Along the way a target of *-unknown-eabi is defined as
"Freestanding" so that TARGET_OS checks have something to work with.

Patch by Sandeep Patel!

llvm-svn: 79296

Controlled via the --enable-llvmc-dynamic-plugins option.

llvm-svn: 74784

Controls whether libCompilerDriver should be loaded dynamically. By default this
is needed only on Win32, to make dynamic plugins work.

llvm-svn: 74759

Add a --enable-profiling option to configure to build Debug+Profile and
Opt+Profile tools.  Now we can profile any kind of flavor we build.

there.

This changes the interpreter to use libffi. After this patch, the interpreter
will barely be able to call any external functions if built on a system without
libffi installed (just enough to pass 'make check' really). But with libffi,
we can now call any function that isn't variadic or taking a struct or vector
parameter (but pointer to struct is fine). Patch by Alexei Svitkine!

runnable on the build machine.

There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.

Thanks to Eric C. and Devang P. for pre-commit review.
