aarch64: Add support for Armv8-R system registers
This patch adds support for the system registers introduced in Armv8-R
AArch64.
gas/ChangeLog:
2020-09-08 Alex Coplan <alex.coplan@arm.com>
* config/tc-aarch64.c (parse_sys_reg): Also pass sysreg name to
validation function.
(parse_sys_ins_reg): Likewise.
(print_operands): Pass CPU features to aarch64_print_operand().
* testsuite/gas/aarch64/v8-r-bad-sysregs.d: New test.
* testsuite/gas/aarch64/v8-r-bad-sysregs.l: Error output.
* testsuite/gas/aarch64/v8-r-bad-sysregs.s: Input.
* testsuite/gas/aarch64/v8-r-sysregs-need-arch.d: New test.
* testsuite/gas/aarch64/v8-r-sysregs-need-arch.l: Error output.
* testsuite/gas/aarch64/v8-r-sysregs.d: New test.
* testsuite/gas/aarch64/v8-r-sysregs.s: Input for previous two tests.
include/ChangeLog:
2020-09-08 Alex Coplan <alex.coplan@arm.com>
* opcode/aarch64.h (aarch64_sys_ins_reg_supported_p): Also take
system register name in order to simplify validation for v8-R.
(aarch64_print_operand): Also take CPU feature set, as disassembly for
system registers now depends on arch variant.
opcodes/ChangeLog:
2020-09-08 Alex Coplan <alex.coplan@arm.com>
* aarch64-dis.c (print_operands): Pass CPU features to
aarch64_print_operand().
* aarch64-opc.c (aarch64_print_operand): Use CPU features to determine
preferred disassembly of system registers.
(SR_RNG): Refactor to use new SR_FEAT2 macro.
(SR_FEAT2): New.
(SR_V8_1_A): New.
(SR_V8_4_A): New.
(SR_V8_A): New.
(SR_V8_R): New.
(SR_EXPAND_ELx): New.
(SR_EXPAND_EL12): New.
(aarch64_sys_regs): Specify which registers are only on
A-profile, add R-profile system registers.
(ENC_BARLAR): New.
(PRBARn_ELx): New.
(PRLARn_ELx): New.
(aarch64_sys_ins_reg_supported_p): Reject EL3 registers for
Armv8-R AArch64.
