Those should be fixed=C2=A0 in the latest version of = this patch (v3), so please take a look and let me know if there is anyt= hing else that should be changed. Kind Regards, Stefan -------- Original Message -------- Subject: [PATCH v3 0/8] target/ppc: Optimize emulation of some Altivec Date: Monday, June 24, 2019 12:10 CEST From: Stefan Brankovic To: stefan.brankovic@rt-rk.com =C2=A0Optimize emulation of ten Altivec instructions: lvsl, lvsr, vsl, = vsr, vpkpx, vgbbd, vclzb, vclzh, vclzw and vclzd. This series buils up on and complements recent work of Thomas Murta, Ma= rk Cave-Ayland and Richard Henderson in the same area. It is based on devi= sing TCG translation implementation for selected instructions rather than using = helpers. The selected instructions are most of the time idiosyncratic to ppc pla= tform, so relatively complex TCG translation (without direct mapping to host instruction that is not possible in these cases) seems to be the best o= ption, and that approach is presented in this series. The performance improvem= ents are significant in all cases. V3: Fixed problem during build. V2: Addressed Richard's Henderson's suggestions. Fixed problem during build on patch 2/8. Rebased series to the latest qemu code.
