------- Comment #9 from amodra at bigpond dot net dot au 2005-11-24 08:59 ------- Indeed it's not a stack slot. Instead, reg 1824 is an invariant, equal to sfp+16512. Code in reload1.c:eliminate_regs_1 substitutes r1 for sfp, then reorganises the order of the additions, so we get (r1+r11)+const not (r1+const)+r11. This of course isn't a valid address on powerpc, where indexed addresses can't take an offset.
In case it isn't obvious, I'm a little lost. Hopefully my analysis will let someone more familiar with reload sort this out. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24997
