From a10a673ad1db72ecf626c12bc95de97369b590d0 Mon Sep 17 00:00:00 2001 From: hjl Date: Fri, 8 Feb 2019 11:30:53 +0000 Subject: [PATCH] i386: Use OI/TImode in *mov[ot]i_internal_avx with AVX512VL OImode and TImode moves must be done in XImode to access upper 16 vector registers without AVX512VL. With AVX512VL, we can access upper 16 vector registers in OImode and TImode.
