[PATCH v6 1/2] x86: Convert CONST_WIDE_INT/CONST_VECTOR to broadcast
H.J. Lu
hjl.tools@gmail.com
Mon Jun 28 22:16:24 GMT 2021
1. Update move expanders to convert the CONST_WIDE_INT and CONST_VECTOR
operands to vector broadcast from an integer with AVX.
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.
A small benchmark:
https://gitlab.com/x86-benchmarks/microbenchmark/-/tree/vpaddd/broadcast
shows that integer broadcast is faster than embedded memory broadcast:
$ make
gcc -g -I. -O2 -march=skylake-avx512 -c -o test.o test.c
gcc -g -c -o memory.o memory.S
gcc -g -c -o broadcast.o broadcast.S
gcc -o test test.o memory.o broadcast.o
./test
memory : 425538
broadcast : 375260
