-Cinstrument-coverageis a per-crate setting, which makes it possible for instrumented and uninstrumented crates to be mixed during compilation. This must be supported to some extent, because the standard libraries are built without coverage instrumentation, and instrumenting them would be unwanted in ...
a : b; } int c = max(1,3); //实际上 max 被替换 int c = 1 > 3 ? 1 : 3; 如果inline 函数有多条(也不能太多,太多的话编译器不会把其当作 inline 函数),代码就膨胀得很快。如果代码膨胀而造成程序体积过大,inline 会导致额外的内存换页(paging),降低指令还俗缓存装置的命中率(instruction cach...
函数调用的成本:堆栈操作,包括函数地址以及变量的保存等等。inlining函数可以通过将函数体直接内嵌到调用该函数的函数内部,因此可以不用支付这一成本。 但是这回造成代码量的增大,inlining造成的代码膨胀亦会导致额外的换页行为,降低指令高速缓冲装置的命中率,而造成效率的降低。
