--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Note it is already postreload that propagates the %rsi register directly into
vec_concatv2di.  And the reason why DSE does nothing is that since LRA
introduction the DSE spill removal has been disabled and last year even removed
altogether.
Removing the * from the first alternative fixes this.
Uros, what is the purpose of those two *s and can't they be replaced by say ^
or $ ?
