From 07f5f4c683879e844d20d0d4963bbaf1b7cd47b9 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 5 Oct 2018 11:41:41 +0900 Subject: or1k: Add the l.muld, l.muldu, l.macu, l.msbu insns Also fix the incorrect definitions of multiply and divide carry and overflow float. Changes to the instructions are made in the .cpu file, then we regenerate the binutils and sim files. The changes also required a few fixups for tests and additional sim helpers. cpu/ChangeLog: yyyy-mm-dd Richard Henderson Stafford Horne * or1korbis.cpu (insn-opcode-mac): Add opcodes for MACU and MSBU. (insn-opcode-alu-regreg): Add opcodes for MULD and MULDU. (l-mul): Fix overflow support and indentation. (l-mulu): Fix overflow support and indentation. (l-muld, l-muldu, l-msbu, l-macu): New instructions. (l-div); Remove incorrect carry behavior. (l-divu): Fix carry and overflow behavior. (l-mac): Add overflow support. (l-msb, l-msbu): Add carry and overflow support. opcodes/ChangeLog: yyyy-mm-dd Richard Henderson Stafford Horne * or1k-desc.c: Regenerate. * or1k-desc.h: Regenerate. * or1k-opc.c: Regenerate. * or1k-opc.h: Regenerate. * or1k-opinst.c: Regenerate. sim/common/ChangeLog: yyyy-mm-dd Stafford Horne * cgen-ops.h (ADDCFDI): New function, add carry flag DI variant. (ADDOFDI): New function, add overflow flag DI variant. (SUBCFDI): New function, subtract carry flag DI variant.
