--- Comment #19 from Michael Meissner <meissner at gcc dot gnu.org> ---
Power8 fusion is meant to transform:
ADDIS tmp,2,foo@toc@ha
LD reg,foo@toc@l(tmp)
into:
ADDIS reg,2,foo@toc@ha
LD reg,foo@toc@l(reg)
I.e. instead of using a random register for the upper 16-bits, it uses the same
register that is being loaded.
I haven't looked into detail at why this is failing.
