I was excited to see new optimization option for library calls, but currently (21.1.0-rc1) it produces broken code:
https://godbolt.org/z/TazjTxfdz
It does generate REX-CALL and NOP, but
1) CALL type is wrong (relative instead of indirect).
2) NOP is slightly different to the one generated by MSVC: 0F 1F 44 00 08 instead of 0F 1F 44 00 00. Not sure if this is important to system loader or not.
