[PATCH 00/10] target/arm: Various v8.1M minor features
Posted by Peter Maydell 3 years, 6 months ago
This patchseries implements various minor v8.1M new features,
notably the branch-future and low-overhead-loop extensions.

(None of this will get enabled until we have enough to implement
a CPU model which has v8.1M, which will be the Cortex-M55, but
as usual we can get stuff into the tree gradually.)

Patch 1 is a decodetree fix suggested by Richard that is
necessary to avoid wrong-decode of the changes to t32.decode
by later patches.

thanks
