+Subject: [PATCH] [test] Fix finding LLDB tools when building stand-alone
+
+Use both LLDB- and LLVM-specific tool/library directories when LLDB is
+being built stand-alone. This ensures that the freshly-built tools
+(and libraries) are used correctly.
+
+Without this patch, the test suite uses LLVM_TOOLS_DIR and LLVM_LIBS_DIR
+to locate lldb, and set PATH and LD_LIBRARY_PATH. When doing
+a stand-alone build, these variables represent the installed LLVM.
+As a result, tests either fail due to missing lldb executable
+or use an earlier installed LLDB version rather than the one being
+built.
+
+To solve this, additional LLDB_TOOLS_DIR and LLDB_LIBS_DIR variables
+are added and populated using LLVM_*_OUTPUT_INTDIR. Those variables
+contain directories used to output built executables and libraries.
+In stand-alone builds, they represent the build-tree directories
+used by LLDB. In integrated builds, they have the same values as
+LLVM_*_DIR and therefore using them does not harm.
+
+The new variables are prepended to PATH and LD_LIBRARY_PATH to ensure
+that freshly built binaries are preferred over potentially earlier
+installed ones. Furthermore, paths used to locate various tools are
+updated to match appropriate locations.
