insn information.

insn information.

[Johan Rydberg]

hi!

I'm writing a backend for gcc 2.95.2 and have run into some
problems;  lots of the time I get the following error from 
the compiler.

getenv_r.c: In function `_findenv_r':
getenv_r.c:113: Internal compiler error in `find_reloads', at
reload.c:3751

.. I guess it's when it tries to match for insns, .. is
there a way to see on what RTL stmt it fails?  


Another question as well. Below you see and RTL statement.

(insn 4 3 5 (set (reg/v:SI 21)
        (reg:SI 4 %r4)) -1 (nil)
    (nil))

What does the "reg/v" mean? How does it differ from "reg" ?

IIRC, it means the reg is a user variable.
