Merge pull request #40 from AbsInt/inline-asm
GCC-style extended inline asm. The subset implemented is: - zero or one output - output constraints "=r" (to register) or "=m" (to memory) - zero, one or several inputs - input constraints "r" (in register), "m" (in memory), "i" and "n" (compile-time integer constant) - clobbered registers (the 3rd argument) - both anonymous (%3) and named (%[name]) operands - modifiers %R and %Q to refer to the most significant / least significant part of a register pair holding a 64-bit integer. (Undocumented GCC ARM feature.) All asm statements are treated as "volatile", possibly modifying memory and condition codes.
