Variable DECL_SIZE

[Ilya Enkovich]

Hi,

I fall into ssa verification failure when try to pass field's
DECL_SIZE as an operand for CALL_EXPR. The fail occurs if field's size
is not a constant. In such case DECL_SIZE holds a VAR_DECL and I need
to find it's proper SSA_NAME. I thought it may be the default one but
gimple_default_def returns NULL. What is the right way to obtain
correct ssa_name in such case?

Thanks,
Ilya
