The following definitions make use of extended asm, which is not supported by Arm Compiler 5.

void mmu_configure(void *tlb)
{
assert(!mmu_is_enabled());
/* Translation Table Base Register 0 */
cp15_write_ttbr0((unsigned int)tlb);
/* Domain Access Register */
/* only domain 15: access are not checked */
cp15_write_dacr(0xC0000000);
dsb();
isb();
}

Can these instructions be replaced by the intrinsics __dmb(0xF), __dsb(0xF) and __isb(0xF) to achieve same behavior of the compiler?
