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.
