Now that we don't use libtool, we don't need to upgrade it :-)
Thanks to Patrik Hägglund H for noticing it!

Edit the ltdl.h file to #include "llvm/Config/config.h" at the very top. You - might also need to resolve some compiler warnings (typically about - comparison of signed vs. unsigned values). But, you won't find out about - those until you build LLVM (step 13). - 9. Edit the llvm/autoconf/m4/libtool.m4 file so that: - a) in AC_PROB_LIBTOOL macro, the value of LIBTOOL is set to - $(top_builddir)/mklib, not $(top_builddir)/libtool - b) in AC_LIBTOOL_SETUP macro, the variable default_ofile is set to - "mklib" instead of "libtool" - c) s/AC_ENABLE_SHARED_DEFAULT/enable_shared_default/g - d) s/AC_ENABLE_STATIC_DEFAULT/enable_static_default/g - e) s/AC_ENABLE_FAST_INSTALL_DEFAULT/enable_fast_install_default/g -10. 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. -11. Run AutoRegen.sh to get the new macros into configure script -12. If there are any warnings from AutoRegen.sh, go to step 9. -13. Rebuild LLVM, making sure it reconfigures -14.
