This is useful for clients that want to maintain compatibility
across multiple releases of LLVM. Currently users like Klee and
Mesa all have to roll their own 'parse llvm-config --version
output and generate defines' solution.
Also reuse the new macros so that version information is less
redundant/likely to fall out of sync again in the future.

that just uses the new toolchain probing logic. This fixes linking with -m32 on
64 bit systems (the /32 dir was not being added to the search).

configure was silently failing to produce anything in the case
where clang wasn't at tools/clang/, resulting in compilation
errors much later in the build when config.h didn't exist.
llvm-svn: 149563
The CMake build already generated one. Follows clang r149497.
This brings us one step closer to compiling and configuring clang
separately from LLVM using the autoconf build, too.
(I lack the right version of autoconf et al. to regen, but it
was a simple change, so I just updated configure manually.)

Get back getHostTriple.
For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

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:
./configure --help | grep docdir
--docdir=DIR documentation root [DATAROOTDIR/doc/-llvm-]

Original commit message:
llvm-config: Replace with C++ version (was llvm-config-2).

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.
llvm-svn: 145234
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.
llvm-svn: 145214
The problems that llvmc solved have largely been subsumed with the
tasks that the clang driver can accomplish, but llvmc lacks flexibility
and depends too heavily on the EOL'd llvm-gcc.
llvm-svn: 140093
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.
llvm-svn: 139937
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.
llvm-svn: 138323
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).
llvm-svn: 138005
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)

Stefanovic. I removed the part that actually emits the instructions cause
I want that to get in better shape first and in incremental steps. This
also makes it easier to review the upcoming parts.

TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

This is important for the correct lowering of unwind instructions
(which doesn't matter at all) and llvm.eh.resume calls (which does).

AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h.
FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()).
FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future.

Update the cmake and autoconf build system to compile polly
as a shared library if it is checked out into tools/polly. In case
polly is not checked out, nothing changes.
This models the way clang can be added to llvm if checked out to tools/clang.
Also rebuild configure.
Patch contributed by ether.

strange packaging environments. The primary result of this is to expose
a (normally empty) CLANG_RESOURCE_DIR string in the autoconf and CMake builds.
This will in turn be used by a subsequent commit to Clang.
Regenerated configure and config.h.in thanks to Nick. =D

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.

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.

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.

big project switch statement to avoid the incorrect warning.

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.

The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htmhttp://en.wikipedia.org/wiki/MicroBlaze
The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.

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.
llvm-svn: 96559
HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
bison and flex are no longer used.
CAN_DLOPEN_SELF was never used either.
AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
libltdl checks for dlopen.
Add check for AR, it used to be done by AC_PROG_LIBTOOL.
AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
void.
Remove unused m4 files.
Configure can now be generated using autoconf 2.65 too, without any warnings!
