CVS commit: src/gnu/dist/gcc4/gcc

[Nick Hudson <skrll%netbsd.org@localhost>]

Module Name:    src
Committed By:   skrll

        src/gnu/dist/gcc4/gcc: config.gcc

Log Message:
Our userland space register convention isn't as flat as it needs to be
for MASK_NO_SPACE_REGS. The assumption is that sr4-sr7 == process space
id, but we have sr7 = kernel space id (0). This was inherited from
OpenBSD.

If sr4-sr7 == process space id, then

        ldw     %r1(,%r2),%r3
and
        ldw     %r2(,%r1),%r3

are equivlent for all values of %r1 and %r2.

If the right compat stuff is in place we can change the space register
convention and turn MASK_NO_SPACE_REGS back on.
