hashcat/src/modules/module_70200.c
Jens Steube b02b1b5033 - Add code to recognize Microsofts OpenCL D3D12 platform 
- Skip memory-free detection on MS OpenCL platform to avoid crashes
- Improve salt usage of 70100/70200, use decoder/kernels from 8900
- Add REPLACE bridge type support (eg. BRIDGE_TYPE_REPLACE_LOOP)
- Switch 70000, 70100 and 70200 to BRIDGE_TYPE_REPLACE_LOOP
- Add synchronization barriers on d2h copy when using bridges
- Improve speed status display updates when using bridges
- Set AMD_DIRECT_DISPATCH=0 to reduce CPU burning loop on AMD backends
- Set benchmark/selftest hash on 70100/70200 to 16:8:1
