ICE: QImode(not SImode) operand should be passed to gen_vec_initv16qiqi in ashlv16qi3.
ix86_expand_vector_init expects vals to be a parallel containing
values of individual fields which should be either element mode of the
vector mode, or a vector mode with the same element mode and smaller
number of elements.
But in the expander ashlv16qi3, the second operand is SImode which
can't be directly passed to gen_vec_initv16qiqi.
gcc/ChangeLog:
PR target/104451
* config/i386/sse.md (<insn><mode>3): lowpart_subreg
operands[2] from SImode to QImode.
gcc/testsuite/ChangeLog:
PR target/104451
* gcc.target/i386/pr104451.c: New test.
