>It's a nice reminder that for the ultimate performance, there is no substitute for knowing exactly what the assembler is doing.
I didn't realize viewing the assembly of a compiled binary was something reserved for C. Someone should tell rust.godbolt.org that it's not supposed to exist.
I think their point is that C is sufficiently close to assembler that you know exactly what assembly any given line of C will produce. This is an old canard which is not really true (https://zenhack.net/2015/08/02/c-is-not-portable-assembly.ht...), but it's common among people who derive a sense of identity from writing C.
