The support for accessing the ARMv8.1 PSTATE field PAN allows instructions of the form MSR PAN, #<imm> with <imm> any unsigned 4-bit integer. However, the architecture specification requires that the immediate is either 0 or 1. This patch implements the constraint on the immediate, generating an error if the immediate operand is invalid, and adds tests for the illegal forms. opcodes/ 2015-11-19 Matthew Wahab <matthew.wahab@arm.com> * aarch64-opc.c (operand_general_constraint_met_p): Check validity of MSR PAN immediate operand. gas/testsuite/ 2015-11-19 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/pan-illegal.d: New. * gas/aarch64/pan-illegal.l: New. * gas/aarch64/pan.s: Add tests for invalid immediates.
