Need a test case that tests DWARF with .o in .a files test/functionalities/archives: Produces libfoo.a from a.o and b.o. Test breaking inside functions defined inside the libfoo.a BSD Archive. test/make/makefile.rules: Some additional rules to sepcify archive building. For example: ARCHIVE_NAME := libfoo.a ARCHIVE_C_SOURCES := a.c b.c llvm-svn: 148066
