1. Update move expanders to convert the CONST_WIDE_INT and CONST_VECTO operands to vector broadcast from an integer with AVX2. 2. Add ix86_gen_scratch_sse_rtx to return a scratch SSE register which won't increase stack alignment requirement and blocks transformation by the combine pass.
A small benchmark: https://gitlab.com/x86-benchmarks/microbenchmark/-/tree/memset/broadcast shows that broadcast is a little bit faster on Intel Core i7-8559U: $ make gcc -g -I. -O2 -c -o test.o test.c gcc -g -c -o memory.o memory.S gcc -g -c -o broadcast.o broadcast.S gcc -g -c -o vec_dup_sse2.o vec_dup_sse2.S gcc -o test test.o memory.o broadcast.o vec_dup_sse2.o ./test memory : 147215 broadcast : 121213 vec_dup_sse2: 171366 $ broadcast is also smaller: $ size memory.o broadcast.o text data bss dec hex filename 132 0 0 132 84 memory.o 122 0 0 122 7a broadcast.o $ 3. Update PR 87767 tests to expect integer broadcast instead of broadcast from memory. 4. Update avx512f_cond_move.c to expect integer broadcast.
