While working with some PPC instructions from a ISA 2.07 POV, I observed
the following :
1. Unlike ISA versions 2.05, 3.0 and 3.1 which have one specific flag
for usage in the insns_flags2 field in the CPUPPCState struct, ISA 2.07
and 2.06 have multiple flags. Upon further investigation, I see that
during CPU intialization (POWER 8+), all those variations of the ISA 2.07
flags are only ever used all together. There is no instance in the code
where a CPU is initialzed in a more granular level, using only a subset
of the ISA 2.07 flag variations.
This patch series hence consolidates the different 2.07 flags, and frees
up bits in the insns_flags2 field for future use. I intend to do the
same analysis for the ISA 2.06 flags as well.
2. The "Summary of changes in Power ISA 2.07B" section in the ISA
version 2.07B mentions : "The icbt instruction has been moved from
the Embedded category to the Base category."
This change has not been incorporated in the QEMU code resulting in
illegal instruction exception upon encountering ICBT instruction in
Power VMs where it should be recognized. Hence adding the necessary
flag to the instruction. Also correcting the invalid mask for the
decoding as per the ISA.
This series is based on top of the patches from another series that I
had posted :

Create a generic ISA 2.07 flag and switch usage of PPC2_VSX207 to it instead. Next commits would consolidate the remaining flags.

Hi Shivang, Thanks for the suggestion. I agree with you. Looking at the shift numbers and making sure they are in consecutive incremental order would make gaps less likely. However if we are to switch to this way, there are about 40 such flags in cpu.h which will have to be reset in this fashion. Hence should be a different patch in itself as the objective of this series is different. Plus it would also bring in the risk of someone shifting a bit by a value that might cause an overflow. So one would have to take care of that while adding a new flag. So this way or the original way, one does need to take care of couple things while adding future flags.
