Subject: Use the PPC no-r0 class on the TOC LD pseudos
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=6375e1b87b089093fecdb09f609251e91d1c2c4f;p=oota-llvm.git

Use the PPC no-r0 class on the TOC LD pseudos

The register parameter in these instructions becomes the base register in an
r+i ld instruction (and, thus, cannot be r0).

This is not yet testable because we don't yet allocate r0 (and even then any
test would be very fragile).
