Author: jhb Date: Wed Aug 23 23:30:25 2017 New Revision: 322824 URL: https://svnweb.freebsd.org/changeset/base/322824 Log: Improve the coverage of debug symbols for MK_DEBUG_FILES. - Include debug symbols in static libraries. This permits binaries to include debug symbols for functions obtained from static libraries. - Permit the C/C++ compiler flags added for MK_DEBUG_FILES to be overridden by setting DEBUG_FILES_CFLAGS. Use this to limit the debug information for llvm libraries and binaries.
