Jonathan Roelofs ebb83ea837 Deprecate in-source autotools builds This is a followup from: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20150323/268067.html Upgrade instructions: $ mv llvm/include/llvm/Config/config.h ./config.h.BACKUP # copy the configure line from line 7 of llvm/config.log # (for example: `$ ./configure --no-create --no-recursion`) $ mkdir build $ cd build # run the configure line, but this time with '../llvm' at the beginning: $ ../llvm/configure --no-create --no-recursion These warnings will soon be turned into hard errors after a week. Speak up now if this is going to be a problem for you. llvm-svn: 236399		2015-05-04 02:04:54 +00:00

Upgrading autoconf
===============================================================================

If you are in the mood to upgrade autoconf, you should:

 1. Consider not upgrading.
 2. No really, this is a hassle, you don't want to do it.
 3. Get the new version of autoconf and put it in <SRC>
 4. configure/build/install autoconf with --prefix=<PFX>
 5. Run autoupdate on all the m4 macros in llvm/autoconf/m4
 6. Run autoupdate on llvm/autoconf/configure.ac
 7. Regenerate configure script with AutoRegen.sh
 8. If there are any warnings from AutoRegen.sh, fix them and go to step 7.
 9. Test, test, test.
