ChangeLog says this is probably my fault...
c_build_vec_perm_expr is missing some code like we can find in build_x_unary_op
for instance:
if (processing_template_decl)
{
if (type_dependent_expression_p (xarg))
return build_min_nt_loc (loc, code, xarg, NULL_TREE);
xarg = build_non_dependent_expr (xarg);
}
RID_BUILTIN_SHUFFLE is handled very early in parser.c which directly calls
c_build_vec_perm_expr. I guess we could use build_min_nt(VEC_PERM_EXPR,...) to
store the template version, and make sure that c_build_vec_perm_expr is called
once the types are instantiated (in tsubst_copy(_and_build)?).
