Hi; this is the second version of a64-third-fourth-set, which
implements support for more or less all A64 instructions except
* FP [we support simple FP register load/store and
transfer to/from the general purpose registers]
* Neon
* system instructions (either ones only available to system
mode or which only make sense for system mode like LDRT)
(There may also be one or two obscure gaps like the CRC32 instruction.)
Changes v1->v2:
* finally got the ld/st pair decode correct
* cleaned up the other ld/st decode to use extract32 rather than bitops
* special case the simple-multiply in 3-src data ops
* move set_pc in mrs/msr down to the end-of-loop handling
* fix use of tcg temp over bblk end and possible gcc warning in cond-compare
* use new qemu ld ops in ldst excl
* revised version of sysregs support:
+ new .state field to specify whether register is AA64, AA32 or both
+ support shared register definitions between both states
+ new patch pulling the inner loop body of the 'define a reginfo'
function out into its own function, for clarity
+ move the AA64 TLS register definitions to be together with the AA32
ones rather than in a completely different part of the file
* added a couple of minor bugfixes to aarch64 linux-user support found
in testing (the clone bugfix in particular is necessary for fork())
* added a patch to add the aarch64 targets to the travis test matrix
(That looks like a long list but it's mostly minor stuff apart from
the adjustments to sysregs support.)
This patchset sits on top of upstream master (yay); git tree
available at:
git://git.linaro.org/people/peter.maydell/qemu-arm.git a64-third-fourth-set
web UI:
https://git.linaro.org/people/peter.maydell/qemu-arm.git/shortlog/refs/heads/a64-third-fourth-set
(My plan for the next patchset is basically "softfloat
fixes and all of FP"; we have working and tested code
that basically just needs a touch more cleanup.)
thanks
