ARM Compiler 6: Armclang

caotianxiang
  1. ARM Compiler 6 uses armclang, but armclang can't use the intrinsic functions(like __qadd) that has used in the previous compiler.How can I get the optimization code? (Does the intrinsic functions are better than the our codes,what are the codes in the function "_qadd"?
  2. Does the __saturate int the "dspfns.h" is error? it does not need to do double?

    Hi caotianxiang,

    regarding 1, it seems almost all the intrinsic were abandoned in the ARM Compiler 6. However, you can make the equivalent functions by using the __attribute__((always_inline)) function attribute and the __asm keyword (i.e. inline assembler).


    Regarding 2, I am afraid the "dspfns.h" is no longer supported in the ARM Compiler 6.
    Anyway, I am not familiar to the armcc or armclang and my answers might be wrong.

    Best regards,
    Yasuhiko Koumoto.
