--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
One possibility would be to guard the
bitmap_set_bit (dce_worklist, SSA_NAME_VERSION (gimple_assign_lhs (stmt)));
on if (optimize && !optimize_debug)
or maybe just if (optimize).
For -Og -g it actually works fine, we get
- ci = COMPLEX_EXPR <_2, _4>;
+ ci_8 = COMPLEX_EXPR <_2, _4>;
+ # DEBUG ci => ci_8
from ssa pass and
- ci_8 = COMPLEX_EXPR <_2, _4>;
- # DEBUG ci => ci_8
+ # DEBUG ci => __complex__ (1.0e+0, 2.0e+0)
from fre1.
While for -Og we can get var-tracking-assignments for this, for -O0 we can't.
