# To run LTO in the xnu project while linking the final result in KCB, without losing debugging info,
# run ld -r on only the LTO bitcode object files to produce one mach-o for KCB to use, which is added
# to the static link archive, along with the non-LTO objects (not linked, since ld -r on mach-o objects
# does not preserve DWARF.)

# 1) $(KERNEL_FILE_NAME).unstripped    (raw linked kernel, unstripped)
# 2) $(KERNEL_FILE_NAME)               (stripped kernel, with optional CTF data)
# 3) $(KERNEL_FILE_NAME).dSYM          (dSYM)
# 4) $(KERNEL_FILE_NAME).link          (bits for static linking)
# 5) lib$(KERNEL_FILE_NAME).a          (static archive for testing)

# has its install target run serially with respect to other primary
