We now support two styles of debug information generation, the '.debug' style, which is the same as previously implemented. This style simply splits the debug information and makes it available in the same general directory. /bin/foo -> /bin/.debug/foo The new 'debug-file-directory' style splits the debug information and places it into the single debug-file-directory, /usr/lib/debug: /bin/foo -> /usr/lib/debug/bin/foo.debug Both also find and copy all referenced source code to a new /usr/src/debug directory. This allows the -dbg files to be used for stand-a-lone debugging on or off the target device. File stripping is now handled as a seperate operation from file splitting. This allows us to split the debug information, but also leave it in the original file -- or prevent the debug information from being split. Also enhance the comments within local.conf.sample to provide a better understanding of the control the user has over debug file generation. Signed-off-by: Mark Hatle <mark.hatle@windriver.com>
