In the vector + case, use the loop variable to calculate a vector index and use the + referenced element as the dimension's index. Perform bounds checking + on this final index. + (gfc_conv_section_upper_bound): Return null for vector indexes. + (gfc_conv_section_startstride): Give vector indexes a start value + of 0 and a stride of 1. + (gfc_conv_ss_startstride): Adjust for new GFC_SS_VECTOR representation. + (gfc_conv_expr_descriptor): Expand comments.
