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.

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

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!

with a 64-bit kernel, which confuses LLVM. Make LLVM double-check this by
checking which defines the system gcc actually sets.

that all the Makefiles changed mode.
Fix this by tellint install-sh to chmod
only to 0644, these are not executable files after all!

plain wrong since $module was never defined so we always get .so which is
broken on Darwin. Just force it to .dylib.

Demote check for bison from error to warning and make sure that the
makefile can handle an empty definition for BISON variable.

Fix problem setting the USE_{program} variable. It should be set to a
Makefile variable definition line, not just "1". Problem noted by
Kenneth Hoste.

Fix problem noticed by Kenneth Hoste. The wrong name for a variable was
being set and subsequently uses of the correct name were empty.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)
Add configure options for getting the correct option for including a whole
archive when linking.

Add a macro for getting the build host extension for executable. Patch
contributed by Anton Korobeynikov. Thanks!

in projects/sample/autoconf.

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.
This version is now ready for testing by users.

* Make it possible to pass a fourth argument to the CHECK_PROGRAM_SANITY
macro that controls whether a non-sane program generates an error or
a warning.

for the command line options. This helps with situations where the executable
name sought is too generic and a more meaningful name needs to be used for
the command line options. It also helps satisfy picky project leaders.

* FIND_STD_PROGRAM will find a program in the path or using --with options
and verify that the path/bin/program is executable. Also allows checking
for include files and libraries. If found, USE_PROGRAM is set, otherwise
its not set. Also sets PROGRAM_BIN (bin directory), and PROGRAM_DIR (top
level directory). If headers are found, sets PROGRAM_INC. If libraries
are found, sets PROGRAM_LIB.
* CHECK_PROGRAM_SANITY can be used to run a program with some option that
only produces information output and requires no input. If the output
matches a regular expression, the program passes the sanity check.
Otherwise, an error occurs.

is in ${srcdir}/autoconf because that is only true if the project is LLVM.
For other projects (e.g. sample), we don't want to have to distribute the
mkinstalldirs or install-sh programs because it opens a window of breakage
for projects. So, this change requires that the llvm_src variable be set
up via another AC_CONFIG_COMMANDS call. For LLVM this is done in the
configure.ac. For projects its done in the LLVM_CONFIG_PROJECT macro.

takes care of the --with-llvmsrc and --with-llvmobj options for the project
It was moved here from the project's configure.ac file because there is
some tricky handling of the llvm_src variable to tell the project where the
llvm source tree is (for mkinstalldirs and install-sh commands).
