Installing Free Ssl Tls Certificates From Let S Encrypt On Iis In For o0, whether march=native or march= is the default still specifies the same family, so both are perfectly compatibly with o0; and whenever another optimization level is specified, march=native is beneficial to performance. so, for me, the fact that o0 is the default doesn't matter for march 's default. March=foo implies mtune=foo unless you also specify a different mtune. this is one reason why using march is better than just enabling options like mavx without doing anything about tuning. caveat: march=native on a cpu that gcc doesn't specifically recognize will still enable new instruction sets that gcc can detect, but will leave mtune=generic. use a new enough gcc that knows about.

Yes, gcc clang march=native detects isa extensions supported by the host system and enables all of them. is also detects what cpu it actually is, and enables mtune=icelake client or mtune=znver4 or whatever which can affect instruction selection choices and for example mprefer vector width=512 on zen 4 vs. 256 on other avx 512 cpus. Is there a way to get gcc to output the available march=arch options? i'm getting build errors (tried march=x86 64) and i don't know what my options are. the compiler i'm using is a proprietary.

I saw these two kinds of make parameters: make march=corei7 avx xxxx xxxx make march icelake server xxxx xxx arch is understood, what's the m meaning? where can i find which arch can be used. Error: bad value for march= switch asked 12 years, 6 months ago modified 9 years, 11 months ago viewed 8k times. There is no ` march=generic' option because ` march' indicates the instruction set the compiler can use, and there is no generic instruction set applicable to all processors. in contrast, ` mtune' indicates the processor (or, in this case, collection of processors) for which the code is optimized. I'm compiling my c app using gcc 4.3. instead of manually selecting the optimization flags i'm using march=native, which in theory should add all optimization flags applicable to the hardware i'm.
