[PATCH v2 0/3] target/ppc: Implement Vector Expand/Extract Mask and Vector Mask

Posted by matheus.ferst@eldorado.org.br 4 years, 2 months ago

From: Matheus Ferst <matheus.ferst@eldorado.org.br>

This is a small patch series just to allow Ubuntu 21.10 to boot with
-cpu POWER10. Glibc 2.34 is using vextractbm, so the init is killed by
SIGILL without the second patch of this series. The other two insns. are
included as they are somewhat close to Vector Extract Mask (at least in
pseudocode).

v2:
- Applied rth suggestions to VEXTRACT[BHWDQ]M and MTVSR[BHWDQ]M[I]

I am planning to include these patches in the next ppc pull request
for QEMU 7.0 since they fix support for recent glibc/distros. Unless
something still needs to be done fpr patch 2+3.

Thanks,

C.
