directories if it can't find them. Then, replace those values into the configure.ac script and pass them to the LLVM_CONFIG_PROJECT so that the values become the default for llvm_src and llvm_obj variables. In this way the user is required to input this exactly once, and the scripts take it from there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27798 91177308-0d34-0410-b5e6-96231b3b80d8
