#
# assembler source files are now handled in a radically different
# fashion. We build a pre-processor program, asmtrans, that
# takes the .spp files, merges them with an include file that
# gives various offsets into structures of interest, and produces
# the .s files as output. This has two major advantages:
# (1) it lets us use the same source for both the Lattice and
#     gcc assembler files (the translator will convert), and
# (2) if we change the CONTEXT or PROC structures, we don't
#     have to dig through the source code looking for
#     magic numbers

# the asm translator program
# Note that this must be compiled with the native CC of whatever
# system you're using; see the definitions at the top of this
# file.
