Hmm, looks like it also causes below failures:
aarch64_be-none-elf:
FAIL: gcc.c-torture/execute/pr57130.c -O1 execution test
FAIL: g++.dg/torture/vshuf-v8si.C -O2 execution test

Lto is unnecessary to reproduce it:
./gcc bf64-1.c -fno-diagnostics-show-caret -fdiagnostics-color=never -O2 -w -lm
-o ./bf64-1.exe -march=armv7-a
Thanks,
bin
