Since r274986 with the patch from
https://gcc.gnu.org/ml/gcc-patches/2019-08/msg02018.html, I've noticed ICEs on
armeb (arm big-endian cross compiler):
gcc.c-torture/execute/pr37573.c -O3 -fomit-frame-pointer -funroll-loops
-fpeel-loops -ftracer -finline-functions (internal compiler error)
gcc.c-torture/execute/pr37573.c -O3 -g (internal compiler error)
gcc.dg/vect/fast-math-pr35982.c (internal compiler error)
gcc.dg/vect/pr55857-1.c (internal compiler error)
gcc.dg/vect/pr55857-1.c -flto -ffat-lto-objects (internal compiler error)
