-Upgrading Libtool
-===============================================================================
-
-If you are in the mood to upgrade libtool, you must do the following:
-
- 1. Get the new version of libtool and put it in <SRC>
- 2. configure/build/install libtool with --prefix=<PFX>
- 3. Copy <SRC>/ltdl.m4 to llvm/autoconf/m4
- 4. Copy <PFX>/share/aclocal/libtool.m4 to llvm/autoconf/m4/libtool.m4
- 5. Copy <PFX>/share/libtool/ltmain.sh to llvm/autoconf/ltmain.sh
- 6. Copy <PFX>/share/libtool/libltdl/ltdl.c to llvm/lib/System
- 7. Copy <PFX>/share/libtool/libltdl/ltdl.h to llvm/lib/System
- 8. Adjust the llvm/autoconf/m4/libtool.m4 file to ensure that the variable
-    default_ofile is set to "mklib" instead of "libtool"
- 9. Run "autoupdate libtool.m4 ltdl.m4" in the llvm/autoconf/m4 directory.
-    This should correctly update the macro definitions in the libtool m4 
-    files to match the version of autoconf that LLVM uses. This converts
-    AC_HELP_STRING to AS_HELP_STRING and AC_TRY_LINK to AC_LINK_IFELSE, amongst
-    other things. You may need to manually adjust the files.
-10. Run AutoRegen.sh to get the new macros into configure script
-11. If there are any warnings from configure, go to step 9.
-12. Rebuild LLVM, making sure it reconfigured
-13. Test the JIT which uses libltdl
-14. If it all works, only THEN commit the changes.
