Abstract

This proposal uses pragmas to add hints to the compiler.

Rationale

Sometimes generating better code requires runtime profile information. But being a static compiler, not a JIT, the compiler could use such hints from the programmer.

Description

This adds a pragma 'inline' and two values for it: true and false, which influences the inlining of the function they appear in. 'true' means always inline, 'false' means never inline.

These are not attributes because they should not affect the semantics of the function. In particular, the function signature must not be affected.

Usage

pragma(inline, true);
pragma(inline, false);
