The patterns for the following instructions are fixed:
* Rotate Left Doubleword then Clear Right (rldcr[.])
* Rotate Left Doubleword Immediate then Clear Right (rldicr[.])
* Rotate Left Doubleword Immediate then Mask Insert (rldimi[.])

Hello I have also done some work risu. My patches add ppc32 support.
Well my patches were made to work with Mac OS X but they are required
to work with Linux. Do you think you could help port these patches to
Linux?
ppc.risu:
https://patchwork.kernel.org/patch/9697489/
risu_ppc.c:
https://patchwork.kernel.org/patch/9697491/
risu_reginfo_ppc.c:
https://patchwork.kernel.org/patch/9697493/
risu_reginfo_ppc.h:
https://patchwork.kernel.org/patch/9697495/
risugen_ppc.pm:
https://patchwork.kernel.org/patch/9697497/
Add ppc support to configure:
https://patchwork.kernel.org/patch/9697499/
Add verbose option:
https://patchwork.kernel.org/patch/9697501/
Add end of test message:
https://patchwork.kernel.org/patch/9697503/
Add more descriptive comment for mismatch or end of test condition:
https://patchwork.kernel.org/patch/9697505/
