2020-04-21Disallow PC relative for CMPI on MC68000/10Andreas Schwab1-6/+12
The MC68000/10 decodes the second operand of CMPI strictly as destination operand, which disallows PC relative addressing, even though the insn doesn't write to the operand. This restriction has only been lifted for the MC68020+ and CPU32. opcodes: PR 25848 * m68k-opc.c (m68k_opcodes): Allow pc-rel for second operand of cmpi only on m68020up and cpu32. gas: PR 25848 * testsuite/gas/m68k/operands.s: Add tests for cmpi. * testsuite/gas/m68k/operands.d: Update. * testsuite/gas/m68k/op68000.d: Update for new error messages.

2017-09-26Allow the macw and macl instructions to be used on CPUs that have emacs support.Nick Clifton1-0/+14
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).
