Eric Christopher 4b0ae48614 Remove llvmc and assorted build machinery for it.
The problems that llvmc solved have largely been subsumed with the
tasks that the clang driver can accomplish, but llvmc lacks flexibility

Eric Christopher 5883971d00 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.

Ivan Krasin 05e609331c 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.

Ivan Krasin 44306e2e5f 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).

2011-08-18 22:54:21 +00:00
Ivan Krasin 764b0c1408 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)

mike-m e08af303a6 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.

Dan Gohman a1c94049c2 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.

Dan Gohman 91f8ad7bd3 Add an autoconf check for -retain-symbols-file and conditionalize
use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

Daniel Dunbar 4e06a5b8b3 configure: Fix default value for optimize_option, I messed up the test condition
in r86005 and unintentionally changed the default from -O3 to -O2.

 - It's odd the things automated perf testing turns up! :)

 - Also, the configure diff is messed up slightly. It looks like someone either
   didn't regenerate configure correctly (or I didn't), or autoconf has some
   funnyness in it. Eric, any ideas?

This has been at -O2 for so long, that I am slightly nervous that this change
will uncover miscompiles of LLVM on other systems. If that is the case, I think
we should just set the default universally at -O3, and let developers/vendors
use -O3 if they want it and have tested it.

John Criswell 4e61b255e2 Fixed spurious warning problem noticed by Daniel Dunbar. The configure script
now configures prerequisite projects individually but also ignores them in the
big project switch statement to avoid the incorrect warning.

John Criswell f369e779a8 Force configuration of some projects before others. In particular, some
projects rely upon llvm-gcc, the LLVM test suite, and poolalloc.  This ensures
that the aforementioned projects have their object trees created first so that
other projects can find their object trees when they themselves are configured.
