# The script operates by iteratively applying the optimizations that gccas
# and gccld run until there is a difference in the assembly resulting
# from the optimization. The difference is then reported with the set of
# optimization passes that produce the difference.
# optimization passes that produce the difference. The processing
# continues until all optimization passes have been tried. The differences
# for each pass, if they do differ, are placed in a diffs.# file.

# To work around differences in the assembly language format, the script
# can also take two filter arguments that post-process the assembly
