Re: A bug in GCC 2.95.2 for SPARC

[James Cheng <James dot Cheng at eng dot sun dot com>]

Hi Alexandre,

Thanks for your quick reply. However, I do need to use ultrasparc 
instructions. I am wondering if you have a timetable for a better
support of ultrasparc. Is there any way I can track this bug, such
as a bug id number?

Regards,

-James
