<pre>Sorry, the patch previously did nothing because when I upgraded bfgminer I
forgot to add "-S opencl:auto" to the command line parameters.
I applied
0001-SelectionDAG-Factor-ISD-MUL-lowering-code-out-of-DAG.patch
0002-SelectionDAG-Use-helper-function-to-improve-legaliza.patch
0001-R600-SI-Custom-select-64-bit-ADD.patch
With "UP.Threshold = 500" it still doesn't work, while with "UP.Threshold =
100" it works but it's terribly slow: on my HD 7950 10 KH/s compared to 440
KH/s with Catalyst 14.1_beta.
GPU_MAX_ALLOC_PERCENT=100 GPU_USE_SYNC_OBJECTS=1 bfgminer -g 2 --scrypt -o
stratum+tcp://hot.wemineltc.com:3335 -u user.1 -p password -I 13 -S opencl:auto
These are the parameters which give me the best results with Catalyst and they
simply hang my system with radeon.</pre>
