From 7906847768613ea6b6e737f3295c77cdb4ff67f4 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 6 Sep 2022 10:34:11 +0200 Subject: [PATCH] target/i386: reimplement 0x0f 0x3a, add AVX The more complicated operations here are insertions and extractions. Otherwise, there are just more entries than usual because the PS/PD/SS/SD variations are encoded in the opcode rater than in the prefixes. These three-byte opcodes also include AVX new instructions, whose implementation in the helpers was originally done by Paul Brook .
