   4 Subject: [PATCH] fix compatibility with CPUs not supporting SSE 4.1
   5  instructions
   6
   7 Building without -O1 causes gcc-12 to emit SSE 4.1 instructions which
   8 are not supported on older CPU architectures. This leads to Ceph
   9 crashing on older CPU architectures. -O1 causes those optimizations to
  10 be implemented manually via runtime dispatch.
