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