+# 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.
