This object is meant to own the ObjectFiles and their underlying MemoryBuffer. It is basically the equivalent of an OwningBinary except that it efficiently handles Archives. It is optimized for efficiently providing mappings of members of the same archive when they are opened successively (which is standard in Darwin debug maps, objects from the same archive will be contiguous). Of course, the BinaryHolder will also be used by the DWARF linker once it is commited, but for now only the debug map parser uses it. With this change, you can run llvm-dsymutil on your Darwin debug build of clang and get a complete debug map for it.

/* This is the main file used to produce the basic* objects that are

used for the dsymutil tests.

These are compiled in a couple of different ways (always on a
|
|
Darwin system):
|
|
Basic compilation:
|
|
for FILE in basic1.c basic2.c basic3.c; do
|
|
clang -g -c $FILE -o ${FILE%.c}.macho.x86_64.o
|
|
done
|
|
clang basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o -o basic.macho.x86_64 -Wl,-dead_strip
|
|
|
|
LTO compilation:
|
|
for FILE in basic1.c basic2.c basic3.c; do
|
|
clang -g -c -flto $FILE -o ${FILE%.c}-lto.o
|
|
done
|
|
clang basic1-lto.o basic2-lto.o basic3-lto.o -o basic-lto.macho.x86_64 -Wl,-object_path_lto,$PWD/basic-lto.macho.x86_64.o -Wl,-dead_strip
|
|
rm basic1-lto.o basic2-lto.o basic3-lto.o
|
|
|
|
Archive compilation (after basic compilation):
|
|
ar -q libbasic.a basic2.macho.x86_64.o basic3.macho.x86_64.o
|
|
clang basic1.macho.x86_64.o -lbasic -o basic-archive.macho.x86_64 -Wl,-dead_strip -L.
