Query: gdb for target TX19

["Monika Chaddha" <monika@acmet.com>]

Hi Ian

Thanks for the information. Actually I need gdb for TX19 because I want
to add architecture which matches to TX39 and TX19.My architecture is
also based on R3000A as TX39 and TX19 but there are some differences
also as following:-

1. TX39 and TX19 have 32 general purpose registers but mine has 8 shadow
sets where each shadow set has 32 registers.
2. Exception handling is different in my architecture.
3. My architecture supports 32-bit instructions of TX39 as well as
16-bit instructions .

Now the following questions are arising in my mind:-

1. Can I use R3900 for my architecture because my architecture is also
based on R3000A or R3900 is only for TX39 family?
2. Which files are responsible for register specification?
3. Which are the main files for target specification in gdb? I mean
where I should change to add my target.

If u can give any information in this regard, I'll be really thankful to
u.

Monika

I don't think there is a version of gdb which explicitly supports the
TX19.  But is there anything special about the TX19?  Can't gdb
support it with a generic MIPS target?  The only thing I can really
see going wrong would be a failure to disassemble some special
multiply instruction or something along those lines.
