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.

* Add --enable-debug-runtime option, defaults to disabled
* Pass the new config var, DEBUG_RUNTIME, to Makefiles
* Don't use -Wa,-strip-debug if debug-runtime is enabled

1. Get rid of TOOLLINKOPTS as it is a hold over from llvm-test and only
   used to communicate additional libraries to the linker. The *standard*
   way to do that is with the LIBS variable which this change supports.

2. Allow the TARGETS_TO_BUILD variable to be set from the configuration
   substitution. This is the result of the --enable-target= parameter to
   the configure script.

llvm-svn: 21449

* Consolidate all "install" usage to the install program/script found by
  autoconf which includes the autoconf/install-sh script if necessary
* Change Makefile.rules to not use the -D flag to install but use the
  MKDIR command as necessary.
* Change Makefile.rules to differentiate between installation of executable
  files and regular data files to get the permission modes correct.

llvm-svn: 20294

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

llvm-svn: 20216

a symbolic link making the autoconf name for the directory (LLVM_OBJ_ROOT)
and the "make" name for the directory (PROJ_OBJ_ROOT) different.

llvm-svn: 19607

* Get rid of variables that are duplicates of autoconf variables.
* Rename BUILD_* to PROJ_*
* Define some project related install locations
* Don't assume LLVM's configured values are the project's

llvm-svn: 19589

Make LLVM_ON_UNIX and LLVM_ON_WIN32 available in the makefiles

llvm-svn: 19205

* Use new configuration variables to compute LLVMGCC and LLVMGXX variables.

llvm-svn: 19094

llvm-svn: 18990

libdir for the CFE runtime libraries, not "all bytecode".

llvm-svn: 18881

names that have version numbers in it so this macro, DJ_AC_PATH_TCLSH will
make the necessary checks. The makefile variable TCLSH is set to the path
found.

llvm-svn: 18382

* Provide support for ENABLE_DOXYGEN
* New tools that documentation generation requires

llvm-svn: 18326

llvm-svn: 18254

tool runs Deja-gnu test suites. The 'make' variable RUNTEST is now set
automatically in the Makefile.config file.

llvm-svn: 17359

* "dist" target now builds tar.gz, tar.bz2, and zip files suitable for
  distribution. "dist" can only be run from $(BUILD_OBJ_ROOT) and implies
  a "check".

* made the preconditions not do a recursive make and ensured that they are
  executed sequentially.

* made the messages output by the makefile be prefixed with "llvm" and the
  make level (e.g. llvm[1]: ) in the same way that make does so that the
  messages are uniform and more readable.

* Fixed the tags target so that tags depends on TAGS which contains the
  rules to build a file named TAGS

* Implemented the EXTRA_DIST feature in a few directories to make sure it
  works.

Take settings of LCC and LCC1XX from configure.

llvm-svn: 10902

Remove checks for many common Unix programs. Our build process currently
assumes they are there and makes no provisions for any other world-views.
(We can add some of these checks back at some later time if it should prove
useful, but right now, we do not need to check to see whether "rm" exists.)

Remove checks for many common standard C headers and functions. We assume
ISO/ANSI C++, and we always use the <cfoo> versions of ANSI C's <foo.h>
headers, so these checks will not help anything.

Edit configure's warning messages for clarity and content.

Change checks for "optional" programs to default to using "true" instead of
"false", so that a failure to find, e.g., etags, will be less likely to result
in make failing.

No longer shall we check for --enable-purify or --with-purify options.
No longer shall we propagate these to the Makefiles.

configure regenerated using autoconf-2.57.

Please feel free to send me any questions or comments you have. :-)

YACC as bison -y.  In this way, we ensure that bison is being used, but
the Makefiles have macros for using bison itself and for getting bison to
act like it is traditional yacc.
