["Borkar, Parag \(Parag\)" <borkar@xxxxxxxxx>]

Hi Mark,

Thanks for your quick reply. I am having problem with few instructions
which I would like to transfer from ARMASM to GNU as.

One is ENTRY instruction in ARMASM, how can I do same thing with GNU as?
Then AREA directive,How can do such things in GNU as,like I tried with
.section directive, but I don"t know exactlly, Would you please explain
me that? And last, How can I translate instruction like " {label} % expr
" ,in GNU as.

Please help me.
Thanks in advance,
parag

No; the assembly syntax is incompatible.

We've thought about adding support for the ARM syntax in GNU as, but
it's a substantial project, and we've never had a sufficiently motivated
customer.

Yes.

I'm not aware of such a chart.  However, if you have a specific
question, we can help.  And, we will add these suggestions to our FAQ as
they're developed.
