fold-const.h (get_array_ctor_element_at_index): Adjust.
2019-07-12 Richard Biener <rguenther@suse.de>
* fold-const.h (get_array_ctor_element_at_index): Adjust.
* fold-const.c (get_array_ctor_element_at_index): Add
ctor_idx output parameter informing the caller where in
the constructor the element was (not) found. Add early exit
for when the ctor is sorted.
* gimple-fold.c (fold_array_ctor_reference): Support constant
folding across multiple array elements.
* gcc.dg/tree-ssa/vector-7.c: New testcase.
