Dear Sir,

   I am looking a way to do the vectorization of compiler 
on the gcc. Before I do that, I would like to have your opinion.

0). I study "gcc.info-8, gcc.info-9, gcc.info-10", 
    and trace flow.c a little, so I have basic understanding of RTL. 
    But, I must admit that the whole data structure is very complex.

1). If the routine which I need to write is in RTX level, since
    RTX_CODE doesn't support vector command, I will have to
    put some new codes in "rtx.def". For example,

	DEF_RTL_EXPR(VADD, "vadd", "ee", "c")
	DEF_RTL_EXPR(VSUB, "vsub", "ee", "c")

    where VADD is vector-addition. Is that right?

2). The routie loop.c seems to fit my most requirement. Is there any
    document about it except the comments inside the file loop.c ?

3)  Anyone has done it?


Thanks for your help!
