re PR middle-end/68146 (ice in gimple_stmt_nonnegative_warnv_p with -O2)
PR middle-end/68146
PR tree-optimization/69155
* tree-complex.c: Include cfganal.h.
(phis_to_revisit): New variable.
(extract_component): Add phiarg_p argument. Assert that returned
SSA_NAME has non-NULL SSA_NAME_DEF_STMT unless phiarg_p is true.
(update_phi_components): Partly rewrite to use loop over real/imag
components instead of code duplication. If extract_component returns
SSA_NAME with NULL SSA_NAME_DEF_STMT, store SSA_NAME_VAR or
create_tmp_reg into the PHI node instead, and mention the phi triplet
in phis_to_revisit.
(tree_lower_complex): Walk bbs in rpo order. Adjust phis recorded
in phis_to_revisit at the end.
* gfortran.dg/pr68146.f: New test.
* gfortran.dg/pr69155.f90: New test.
