I can not find any benchmarks to demonstrate that though. This would mean: CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fstack-check" Opinions?Seems sound given our focus on IA32 (don't know about other architectures). +1 from me.
Our focus on IA32? -- Sincerely, Johannes Löthberg PGP Key ID: 0x50FB9B273A9D0BB5 https://theos.kyriasis.com/~kyrias/
