#pragma inline forced_no_body
Web5.4.6 #pragma [no]inline Directive. Function inlining is the inline expansion of function calls; it replaces the function call with the function code itself. Inline expansion of functions reduces execution time by eliminating function-call overhead and allowing the compiler's general optimization methods to apply across the expanded code. WebJan 8, 2024 · 4 Answers. Forced inlining in the embedded programming is a very handy tool. It is much safer than than macros (type checking, normal C syntax etc etc). Most of the compilers have extensions to force inlining (or ban it). gcc family compilers (clang, icc ...) in gcc the most common way is to use __attribute__ ( (always_inline))

WebIf you use either the #pragma inline or the #pragma noinline directive in your source, you can later override them with an appropriate IPA link control file directive during the IPA link step. The compiler uses the IPA link control file directive in the following cases: If you specify both the #pragma noinline directive and the IPA link control file inline directive for a function. WebJan 8, 2024 · It turns out that, yes, even though Go does not have macros, or a preprocessor, Go does indeed support pragmas. They are implemented by the compiler as comments. Just to drive home the point, they’re actually called pragmas in the source of the Go compiler. So, clearly the name pragma, along with the idea, isn’t going away.
