[VIRT-198 # QEMU: SVE Emulation Support ]
Fixed a couple of bugs uncovered by Alex's VQ16 traces.
[VIRT-249 # SVE System Mode ]
Tracked a phantom kernel crash for a while before it
magically went away with a qemu from-scratch rebuild.
(Plus other stuff, maybe? I tried a lot of things.)
Wrote a version of helper_sve_ldff1_bb_r that works
on pages, and works with softmmu.
time ./bld/tests/test-strlen
softmmu: 0m5.467s
linux-user (old): 0m2.016s
linux-user (new): 0m1.853s
Still need to generalize this to the other first-fault/
no-fault helpers. And possibly write some synthetic test
cases for them. Certainly they've not been tested so
far by anything.
[QEMU Upstream]
* tcg-next pull request.
* Review of some ppc fpu patches went too many rounds
before I broke down and wrote some patches myself.
* More nanomips review.
[GCC Upstream]
Fixed some problems with, and committed, the movprfx patches.
