Re: objcopy making a mess of converting kernels to a.out format

[Chuck Silvers <chuq%chuq.com@localhost>]

hi,

I put one in ftp://ftp.netbsd.org/pub/NetBSD/misc/chs/arm-aout/netbsd.

it's easy enough to make one yourself, though.
just add a global variable like:

        const char foo[0x800] = { 1 };

to some .c file, and adjust the 0x800 so that link_set sections extend
into another page after the .text section (like in the example below).
