Hi all,

Can any one get me the information/implementation of  below mentioned
functions?

1. operands[0] = gen_rtx_REG (SImode,REGNO (set_dest));
2. operands[0] = gen_highpart (SImode, set_dest);

Are both functionalities similiar if i use the above functions to get
the 32 bit word from a 64 bit register?

Regards,
Rohit
