# check-dirtymark.sh - Host-cc gate for the stage's dirty-band writers: the
# multi-row mark (surfaceMarkDirtyRows, whose four-row groups reuse a group's
# result for the next group that held the same bytes) and the whole-stage
# fills, held byte for byte to the plain per-row widen over randomized band
# states and marks of every height and phase (tests/host/dirtyMarkHost.c).
#
# This is the C marker, which the x86 ports run. The 68000 ports run its twin
# in src/m68k/stageBands.s; scripts/verify-atarist-dirtymark.sh runs the same
# harness against that under Hatari. A wrong mark is invisible to the UBER
# hashes (they hash the surface, not the bands), so this is where it shows.
#
# Built as a whole BLANK-port program (the check-blank.sh source set plus the
# harness). Exits nonzero on any mismatch.
