Progress (another short week, May is full of bank holidays :-)):
* UM-2 [QEMU upstream maintainership]
- usual background level of code review etc
- investigated a bug reported by Mozilla where people running x86 Firefox
on QEMU on Arm hardware were seeing crashes; narrowed down the cause
(aided by Mozilla kindly providing a minimal repro test case),
and Paolo produced a fix.
* QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG]
- Started looking at what is required for FEAT_MOPS (the
memcpy/memset/memmove insns), what they do and how QEMU ought
to implement them.
- The new insns are in the load/store part of the A64 instruction
space. To make this easier to do, we should really convert at
least the integer parts of the A64 decoder to decodetree (a
refactoring we've been putting off for a long time). Started on
the conversion: sent out a first 20-patch patchset that converts
the dp-immediate and branch insns.
