From 94538b6545be9613ee25c80325e3cebf518730cf Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Fri, 16 Aug 2019 16:28:12 +0200 Subject: [PATCH] mmx.md (mmxdoublemode): New mode attribute. * config/i386/mmx.md (mmxdoublemode): New mode attribute. (mmx_uavg3): Macroize expaner from mmx_uavgv8qi3 and mmx_uavgv4hi3 using MMXMODE12 mode iterator. (uavg3_ceil): New expander. * config/i386/sse.md (uavg3_ceil): Use ssedoublemode mode iterator when creating CONST1_RTX. (_uavg3): Ditto. (*_uavg3): Use ssedoublemode mode iterator for const1_operand predicate.
