lra.c (lra): Clear lra_optional_reload_pseudos before every constraint pass.
2013-09-10 Vladimir Makarov <vmakarov@redhat.com>
* lra.c (lra): Clear lra_optional_reload_pseudos before every
constraint pass.
* lra-constraints.c (curr_insn_transform): Switch on optional
reloads. Check destination too to check move insn.
(undo_optional_reloads): Add check that the original peudo did not
changed its allocation and the optional reload was inherited on
last inheritance pass. Break loop after deciding to keep optional
reload.
(lra_undo_inheritance): Add check that inherited pseudo still in
memory.
