* gas/config/tc-arm.c (arm_ext_adiv): New variable.
(do_div): New function. (insns): Accept UDIV and SDIV in ARM state. (arm_cpus): The cortex-a15 option has all current v7-A extensions. (arm_extensions): Add 'idiv' extension. (aeabi_set_public_attributes): Update Tag_DIV_use values for the Integer Divide extension. * gas/doc/c-arm.texi: Document the idiv extension. * gas/testsuite/gas/arm/armv7-a+idiv.d: New test. * gas/testsuite/gas/arm/armv7-a+idiv.s: Likewise. * gas/testsuite/gas/arm/attr-march-all.d: Update for Integer divide extension. * gas/testsuite/gas/arm/attr-march-armv7-a+idiv.d: New test. * include/opcode/arm.h (ARM_AEXT_ADIV): New define. (ARM_ARCH_V7A_IDIV_MP_SEC): Likewise. * opcodes/arm-dis.c (arm_opcodes): Support disassembly of UDIV and SDIV in ARM state.
