[PATCH] Add POLY_INT_CST support to fold_ctor_reference in gimple-fold.cc
Add POLY_INT_CST support to code within
fold_ctor_reference. This code previously
only supported INTEGER_CST which caused a
bug when using VEC_PERM_EXPR with SVE vectors.
gcc/ChangeLog:
* gimple-fold.cc (fold_ctor_reference):
Add support for poly_int.
