# Translate SubX by running the self-hosted translator natively on Linux.
#
# Possible knobs:
#   Whether to run a phase natively or in emulated mode.
#     This script is for running natively.
#   Whether to stop after a phase.
#     This script assumes inputs are already working so doesn't easily show
#     which phase an error happens in.
#   Whether to trace a phase. Whether to always trace or rerun with tracing
#   enabled after an error.
#     Leave tracing to other scripts. We save intermediate files so it's easy
#     to rerun a single phase afterwards.
#   Whether to run a phase with debug information. (Need to juggle multiple
#   sets of debug files.)
#     Again, that's for subsequent scripts.

# A little hack. We want translate_subx to always emit identical binaries to
# the C++ translator. The C++ translator assorts segments before it processes
# string literals, so we follow the same order above.
#
# However, dquotes currently emits a separate data segment for string literals.
# So we need to run assort a second time to clean up after it.
#
# Potential solutions:
#   a) modify C++ translator to process string literals before assorting.
#   b) clean up dquotes to assume assorted segments, and append to the
#   existing data segment.
