This facility allows LLVMLIBS to be specified with something like:
LLVMLIBS = config --libs jit
instead of:
LLVMLIBS = JIT
with the same effect. However, the llvm-config utility is much more versatile
than the single keyword approach. Note that "config" is the keyword after
which any arguments to llvm-config are allowed. When llvm-config is tested
and working well, we'll start using this and drop support for the JIT
keyword.

* Make runtimes and projects build with the new front-end by not relying on

2. Make LLVMTransformUtils a relinked object file and always link it before

pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.

Move the implementation of the fix from Makefile.rules to Makefile. This
ensures that it is only checked on a top-level rebuild, and not in every
single subdirectory. This removes some annoying messages from the build and
numerous executions of config.status if the .in file changes but not
substantively enough to cause the .h file to be modified by config.status.

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.

1. Allow DIST_CHECK_CONFIG_OPTION to specify a set of options to be passed
to the configure script during the dist-check target. This allows things
to be passed down on a project basis so the configure doesn't fail.
2. Use the tar | (cd ; tar ) idiom to copy files which is more flexible

When llvm-gcc is not available, bypass rules for Modules and Bytecode
Libraries that require llvm-gcc and emit instead a warning that llvm-gcc

passes the -module option on the libtool command line to ensure that the
shared library being built can be dlopened and dlsym can work on that
module. LOADABLE_MODULE should be sent only in conjunction with the
SHARED_LIBRARY directive. It should generally be used for any module that
is intended to be the target of an LLVM -load option. Note that loadable
modules will not have the lib prefix but otherwise look like shared
libraries. This is per the libtool recommendations and prevents these
special shared libraries from being linked in via -l option to the linker.

files that USE the .inc file unless the contents of the .inc file changes.
This should fix the problem where reconfiguring causes all targets to be
completely rebuilt (because config.h is usually modified, causing libsystem
to be rebuilt, causing tblgen to be rebuilt, causing .inc files to be
rebuilt, causing .o files to be rebuilt).
This patch also checks in a gross hack where .o files now explicitly depend
on $(BUILT_SOURCES), to avoid problems where the .inc files are not completely
generated before the .o files start to compile.

Change construction of bytecode libraries from producing a single bytecode
file to producing a library containing bytecode files. This gets around the
problem of multiple symbol definitions in the linker if something like
-lc -lc is attempted on the command line. Previously this happened because
the linker would find libc.bc as a "library". It will now find libc.a which
it can simply search for missing symbols instead of linking in wholesale.

Modified build rules so that source files generated during the build are placed
in the build directory and not the source directory (and not in a Debug
directory). This makes the system cleaner and allows us to have a read-only
source tree.

Moved Makefile.common to Makefile.rules. This makes project Makefiles easier
to support, and allows for easier overriding of default configuration values
that used to be in Makefile.common.
Modified Makefile.config.in to determine paths for directories (like
LLVM_SRC_ROOT) and to use the pwd binary as opposed to the shell builtin (this
works better for symbolic links).

and explicitly declare all the ones we're using for LLVM.
This quickly cancels many of GNU Make's implicit rules and reduces build time.
The only caveat is that any new suffixes may need to be explictly added to
the .SUFFIXES pseudo target.
Removed the -only-static option as it is no longer used.

broken by libtoolification anyways, and noone can use it because purify doesn't
support the 64-bit sparc compilers even if it weren't broken!

the pre-release 1.1 branch and pre-release 1.1.1).
Made the USE_SPEC option work.
Silenced unnecessary error output from the cmp command when checking for
updates to lex/yacc generated files. This fixes a problem where we get error
messages the first time the file is generated.
Fixed the distclean option. It is now in the Makefile (i.e. only runs in the
top level source directory), removes more files, and plays nicely with
external project Makefiles.

The shell AND/OR operators short-circuit on command success/failure, which is
the inverse of exit status (i.e. 0 means success, non-zero means failure).

o Not all versions of diff have the -q option
o The cmp program is probably faster than diff
Fixed the logic that only copies the file over if no differences are found.
