From 58a0b827444d0d6baad47f5fd010f33e541ed16e Mon Sep 17 00:00:00 2001 From: Nick Clifton Date: Tue, 26 Sep 2017 10:33:32 +0100 Subject: Allow the macw and macl instructions to be used on CPUs that have emacs support. From PR 22123: The common opcodes of emac and mac seem to be only implemented for mac. To reproduce: echo "macw %d3l,%a0l" > /tmp/dummy.S m68k-unknown-elf-as -m5208 /tmp/dummy.S Outputs something like: /tmp/dummy.S: Assembler messages: /tmp/dummy.S:1: Error: operands mismatch -- statement `macw %d3l,%a0l' ignored This behavior occurs only if the CPU supports only emac but not explicitly mac (but emac is a superset of mac). --- opcodes/ChangeLog | 6 ++++++ opcodes/m68k-opc.c | 14 ++++++++++++++ 2 files changed, 20 insertions(+) (limited to 'opcodes') diff --git a/opcodes/ChangeLog b/opcodes/ChangeLog index 082d755..e8061b3 100644 --- a/opcodes/ChangeLog +++ b/opcodes/ChangeLog @@ -1,3 +1,9 @@ +2017-09-26 do + + PR 22123 + * m68k-opc.c (m68k_opcodes): Allow macw and macl instructions to + be used on CPUs that have emacs support. + 2017-09-21 Sergio Durigan Junior * aarch64-opc.c (expand_fp_imm): Initialize 'imm'. diff --git a/opcodes/m68k-opc.c b/opcodes/m68k-opc.c index ecad2f4..a6c1a8a 100644 --- a/opcodes/m68k-opc.c +++ b/opcodes/m68k-opc.c @@ -1501,6 +1501,13 @@ const struct m68k_opcode m68k_opcodes[] = {"macw", 4, two(0xa000, 0x0200), two(0xf130, 0x0900), "uMumMheH", mcfemac },/* Ry,Rx,+1/-1,accX. */ {"macw", 4, two(0xa000, 0x0000), two(0xf130, 0x0f00), "uMumeH", mcfemac }, /* Ry,Rx,accX. */ +{"macw", 4, two(0xa080, 0x0000), two(0xf180, 0x0910), "uNuoiI4/Rn", mcfemac }, +{"macw", 4, two(0xa080, 0x0200), two(0xf180, 0x0910), "uNuoMh4/Rn", mcfemac }, +{"macw", 4, two(0xa080, 0x0000), two(0xf180, 0x0f10), "uNuo4/Rn", mcfemac }, +{"macw", 4, two(0xa000, 0x0000), two(0xf1b0, 0x0910), "uMumiI", mcfemac }, +{"macw", 4, two(0xa000, 0x0200), two(0xf1b0, 0x0910), "uMumMh", mcfemac }, +{"macw", 4, two(0xa000, 0x0000), two(0xf1b0, 0x0f10), "uMum", mcfemac }, + {"macl", 4, two(0xa080, 0x0800), two(0xf180, 0x0910), "RNRoiI4/Rn", mcfmac }, {"macl", 4, two(0xa080, 0x0a00), two(0xf180, 0x0910), "RNRoMh4/Rn", mcfmac }, {"macl", 4, two(0xa080, 0x0800), two(0xf180, 0x0f10), "RNRo4/Rn", mcfmac }, @@ -1515,6 +1522,13 @@ const struct m68k_opcode m68k_opcodes[] = {"macl", 4, two(0xa000, 0x0a00), two(0xf130, 0x0900), "RMRmMheH", mcfemac }, {"macl", 4, two(0xa000, 0x0800), two(0xf130, 0x0f00), "RMRmeH", mcfemac }, +{"macl", 4, two(0xa080, 0x0800), two(0xf180, 0x0910), "RNRoiI4/Rn", mcfemac }, +{"macl", 4, two(0xa080, 0x0a00), two(0xf180, 0x0910), "RNRoMh4/Rn", mcfemac }, +{"macl", 4, two(0xa080, 0x0800), two(0xf180, 0x0f10), "RNRo4/Rn", mcfemac }, +{"macl", 4, two(0xa000, 0x0800), two(0xf1b0, 0x0b10), "RMRmiI", mcfemac }, +{"macl", 4, two(0xa000, 0x0a00), two(0xf1b0, 0x0b10), "RMRmMh", mcfemac }, +{"macl", 4, two(0xa000, 0x0800), two(0xf1b0, 0x0910), "RMRm", mcfemac }, + /* NOTE: The mcf5200 family programmer's reference manual does not indicate the byte form of the movea instruction is invalid (as it is on 68000 family cpus).
