Force broadcast constant to mem for vec_dup{v4di,v8si,v4df,v8df} when TARGET_AVX2 is not available.
vpbroadcastd/vpbroadcastq is avaiable under TARGET_AVX2, but
vec_dup{v4di,v8si} pattern is avaiable under AVX with memory operand.
And it will cause LRA/Reload to generate spill and reload if we put
constant in register.
gcc/ChangeLog:
PR target/112992
* config/i386/i386-expand.cc
(ix86_convert_const_wide_int_to_broadcast): Don't convert to
broadcast for vec_dup{v4di,v8si} when TARGET_AVX2 is not
available.
(ix86_broadcast_from_constant): Allow broadcast for V4DI/V8SI
when !TARGET_AVX2 since it will be forced to memory later.
(ix86_expand_vector_move): Force constant to mem for
vec_dup{vssi,v4di} when TARGET_AVX2 is not available.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr100865-7a.c: Adjust testcase.
* gcc.target/i386/pr100865-7c.c: Ditto.
* gcc.target/i386/pr112992.c: New test.
