+Subject: [PATCH] use schedule(static) for the dynamic and guided OpenMP loops
+
+Upstream-Status: Inappropriate [works around a libgomp defect on the riscv64 runners, riseproject-dev/python-wheels#617]
+
+libgomp's dynamic and guided work-share schedules fault on the riscv64
+machines these wheels are built and tested on (see CLAUDE.md gotcha 166).
+copy_fuji_uncropped/copy_bayer in raw2image.cpp run schedule(dynamic) on
+every single postprocess() call regardless of camera or demosaic
+algorithm, and ahd_demosaic.cpp (the default demosaic algorithm) and
+dht_demosaic.cpp (the optional DHT algorithm) run schedule(dynamic)/
+schedule(guided) too, so this is reachable by ordinary decoding, not an
+edge case.
+
+Moving all 16 affected loops in the vendored LibRaw copy to
+schedule(static) costs only load balancing on rows/columns whose
+iterations differ in cost, and buys a wheel that does not crash. Revert
+once the runners' toolchain is fixed.
