+ * config/rs6000/rs6000.opt (-mvsx-align-128): Make options that
+ save to independent variables use the Save attribute. This will
+ allow these options to be modified with the #pragma/attribute
+ target support.
+ (-mallow-movmisalign): Likewise.
+ (-mallow-df-permute): Likewise.
+ (-msched-groups): Likewise.
+ (-malways-hint): Likewise.

+ (-mvectorize-builtins): Likewise.
+ (-msave-toc-indirect): Likewise.
+
+ * config/rs6000/rs6000.c (rs6000_opt_masks): Add more options that
+ can be set via the #pragma/attribute target support.
+ (rs6000_opt_vars): Likewise.
+ (rs6000_inner_target_options): If VSX was set, also set
