Hi Ulrich. The saturated work you're doing at the moment - is it the saturated add/subtract QADD/QSUB/QDADD/QDSUB or the ARMv6 saturate-word-with-shift SSAT/USAT?
Hi Michael, it's the latter (SSAT/USAT).
I've updated the old blueprint and added a new one for SSAT/USAT: https://blueprints.launchpad.net/gcc-linaro/+spec/armv6-saturation- instructions https://blueprints.launchpad.net/gcc-linaro/+spec/armv5-saturated-ops
and was wondering which to put against your name.
I've added myself to the armv6-saturation-instructions blueprint and updated its status.
B.t.w. note that there are also USAT16/SSAT16 (which operate on vectors of two 16-bit integers). My current patch does *not* address those; I'd suggest this to be done in a follow-on blueprint (if at all), possibly in conjunction with other core-register vector operations.
Mit freundlichen Gruessen / Best Regards
Ulrich Weigand
