This patch teaches the AsmParser to accept some logical+immediate instructions and convert them as shown: bic Rd, Rn, #imm -> and Rd, Rn, #~imm bics Rd, Rn, #imm -> ands Rd, Rn, #~imm orn Rd, Rn, #imm -> orr Rd, Rn, #~imm eon Rd, Rn, #imm -> eor Rd, Rn, #~imm Those instructions are an alternate syntax available to assembly coders, and are needed in order to support code already compiling with some other assemblers. For example, the bic construct is used by the linux kernel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212722 91177308-0d34-0410-b5e6-96231b3b80d8
