size of int 24

[brahmaiah vallabhaneni]

Hi,
 I am new to gcc.I am trying to pick up rtl to get
 ready for prting gcc.I have a few doubts. If one of
you could answer I am greatful to you.
 
  1)  Can I have gcc for a machine
where integers are 24 bit long ??

  All other data types float,double and long are 32
bit.

    BITS_PER_WORD also 24
   If so  in which mode should I access them  ??
 (SI,PSI  ??)
   
  2) Can I change the mode sizes in gcc
     (machmode.def)   ??




  thanks and regards

  V.Brahmaiah
