050434f25b For PR848:
1. Get the path to the pwd binary (/bin/pwd usually) from configure.
2. Use that path to run pwd in all path variables set in Makefile.config.in
The hope is that these changes will resolve symlinks to physical paths. This
should work on all platforms where the binary pwd defaults to printing
physical paths. The shell version of pwd generally doesn't (it will print
the symlink path).

dc6201bb05 Changes to support cross-compiling LLVM. The GenLibDeps.pl script needs to
have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.

0b958878bb For PR619:
Make any header files that are automatically generated be preconditions of
the compilation. This ensures that if a *.h.in file is changed then its
corresponding *.h file gets updated on the next rebuild. Note that this can
lead to confusing (but correct) results if the *.h.in file changed
unsubstantially so that autoheader doesn't update the *.h file. In that case,
manually touch the *.h file in question to restore order. Moral of the story,
if you're going to "touch" a *.in file then modify it substantially.

These patches make threading optional in LLVM. The configuration scripts are now
modified to accept a --disable-threads switch. If this is used, the Mutex class

bd640a379e Add two new checks for use in LLVM configuration files:
* 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.

78910545f0 For PR540:
This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
  MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
  The implementation of MutexGuard.h is now based on sys::Mutex which hides
  its implementation and makes it unnecessary to have the -NoSupport.h and
  -PThreads.h versions of ThreadSupport.

* All places in ExecutionEngine that previously referred to "Mutex" now
  refer to sys::Mutex

* All places in ExecutionEngine that previously referred to "MutexLocker"
  now refer to MutexGuard (this is frivolous but I believe the technically
  correct name for such a class is "Guard" not a "Locker").

These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

1ae4c38124 Fix the "stacker doesn't build without llvm-gcc" problem. The configure
script was defaulting the LLVMGCC variable to "llvm-gcc" if it couldn't
find llvm-gcc and --with-llvmgccdir was not specified. In this case, there
is no llvm-gcc available on the system so we shouldn't assume that the
user's path will find it any better than configure could. The fix is to
default it to an empty string. If LLVMGCC is empty, the makefiles will
avoid building things that depend on llvm-gcc and give a nice warning
message to that effect.

options have been added to the configure script that control which targets
will be used. The options are:

--enable-target-this (default=disabled)
  This will specify that the target corresponding to the build host is
  the target that will be compiled/used. You can't use this with any of
  the other options (they'll be ignored). This is what most people want.

--disable-target-x86 (default=enabled)
  This will prevent the X86 target(s) from being compiled/used.

--disable-target-sparc (default=enabled)
  This will prevent both SparcV8 and SparcV9 from being compiled/used.

--disable-target-powerpc (default=enabled)
  This will prevent the PowerPC target from being compiled/used.

--disable-target-alpha (default=enabled)
  This will prevent the Alpha target from being compiled/used.

--disable-target-ia64 (default=enabled)
  This will prevent the IA64 target from being compiled/used.

Note that without any of these options, the default behavior is to build
all targets, as is the current practice.

All these options do is set up the substititution variable TARGETS_TO_BUILD
which contains the targets that should be compiled/used. The variable is
intended to be used in the makefiles. Those changes will come later.

ea15ab69ff Add a call to AC_CONFIG_COMMANDS to ensure that llvm_src is set properly
in the config.status script. This allows the AC_CONFIG_MAKEFILE macro to
work properly after it was changed to support sub-projects.

b48ff21894 This macro cannot assume that the location of install-sh and mkinstalldirs
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.

cb402c429a Add a new macro for configuring projects, LLVM_CONFIG_PROJECT. This 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).

The install target in Makefile.rules no longer uses pax but just uses find
and "install" instead.
