[PATCH 00/20] target/arm: Convert exception, system, loads and stores to decodetree

[Peter Maydell <peter.maydell@linaro.org>]

This patchseries does more of the conversion of the A64 decoder to
decodetree.  It covers the exception-generation, system, load and
store instructions.

After this the remaining legacy decoder pieces are:
 * data-processing (register)
 * data-processing (SIMD)
 * data-processing (floating-point)

I plan to take a break from conversion after this series to work on
FEAT_MOPS, but want to come back to the dp-register parts for this
release cycle.  The FP/SIMD stuff is a bigger job and I'm inclined to
leave it for the moment.

I include the LDSMIN/LDSMAX bugfix as patch 1 to avoid a conflict
later.  Speaking of conflicts, this is going to conflict with RTH's
LSE2 series, which I expect to get in to the tree first, but I'm
hoping the rebase of this series won't be too painful.

thanks
