Detailed Description

`compiler` — Compiler Detection & Intrinsics

Header-only module providing compiler-specific macros and feature-detection. Leaf module with no dependencies.

Public API

Macros only — no classes, structs, or functions.

Usage

#include <helios/compiler/compiler.hpp>
 
if (HELIOS_EXPECT_TRUE(ptr != nullptr)) {
  // __builtin_expect hints the branch predictor on GCC/Clang
}
 
#if HELIOS_MOVEONLY_FUNCTION_AVAILABLE
  using Fn = std::move_only_function<void()>;
#else
  using Fn = std::function<void()>;
#endif

Macros

Macro	Purpose
HELIOS_EXPECT_TRUE(x)	Branch-predictor hint for likely-true paths.
HELIOS_EXPECT_FALSE(x)	Branch-predictor hint for likely-false paths.
HELIOS_FORCE_INLINE	Always inline (equivalent to __attribute__((always_inline))).
HELIOS_ALWAYS_INLINE	Same as HELIOS_FORCE_INLINE.
HELIOS_NO_INLINE	Prevent inlining.
HELIOS_MOVEONLY_FUNCTION_AVAILABLE	Feature-test for std::move_only_function.
HELIOS_CONTAINERS_RANGES_AVAILABLE	Feature-test for C++23 <ranges> on containers.
HELIOS_STL_FLAT_MAP_AVAILABLE	Feature-test for std::flat_map.
