2009-03-05Blackfin arch: fix bug - The SPORT_HYS bit is not set for BF561 0.5Enrik Berkhan
IMHO the setting should depend on ANOMALY_05000305 which is about the availability of the bit, not ANOMALY_05000265 which only describes the SPORT sensitivity to noise (checked for BF561 only, though). If that's not true for other BF variants, maybe the definition of ANOMALY_05000265 for BF561 should be changed to '(1)' instead.

2009-02-04Blackfin arch: Remove outdated codeMichael Hennerich
The removed version with the loop registers saved on the stack was originally intended to workaround the missing toolchain support for LoopReg Clobbers. Since our toolchain now supports these there is no point in keeping this workaround. And since we don't touch LoopRegs anymore we're no longer subject for ANOMALY_05000312.
