# asmcomp.depend contains the dependencies for all the backends, with ifeq used
# to select the correct one depending on the ARCH variable. In order to
# generate this file, we must temporarily replace the $(ARCH_SPECIFIC) files
# with the ones for each architecture. At the end of this process, the files for
# the active architecture (i.e. $(ARCH)) must be restored, but if we simply
# re-link the files we will trigger a complete rebuild of the native compiler
# and .opt binaries. The recipe for asmcomp.depend therefore begins by renaming
# the existing files, then it generates asmcomp.depend and then we rename the
# files back. This means their timestamps are unaltered, and the next invocation
# of make therefore correctly doesn't rebuild anything.
