These two patches implement the last four A64 Neon instructions: SQNEG, SQABS, USQADD, SUQADD meaning that we have complete coverage of the userspace instruction set, with the exception of the optional crypto and CRC instructions. As with the previous set, these are safe changes so I'm planning to get them into 2.0 even though they're not strictly speaking bugfixes. (Specifically, expect to see these plus a few other bugfixes in a pullreq tomorrow aiming at rc1.) Changes v1->v2: use extract32/deposit32 in the USATACC and SSATACC macros rather than raw bit-twiddling. thanks -- PMM Alex Bennée (2): target-arm: A64: Add saturating int ops (SQNEG/SQABS) target-arm: A64: Add saturating accumulate ops (USQADD/SUQADD) target-arm/helper.h | 34 ++++++--- target-arm/neon_helper.c | 187 +++++++++++++++++++++++++++++++++++++++++++++ target-arm/translate-a64.c | 160 +++++++++++++++++++++++++++++++++++--- 3 files changed, 359 insertions(+), 22 deletions(-) -- 1.9.0 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
