Hi all,

  Is there anyone knows what's the difference between CodeSourcery's toolchain and ordinary ARM-GCC toolchain from GNU website specifies "-mabi=aapcs-linux"? Or are there outputs interchangeable?
  Also, Are there any documents specify differences between `apcs-gnu', `atpcs', `aapcs', `aapcs-linux' and `iwmmxt'?

Best wishes,
Meng Sun,
