From df7248039553b3ebd338380c3ef0428b0e046e79 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Fri, 14 Aug 2020 09:38:45 -0400 Subject: common: Make use of [[nodiscard]] where applicable Now that clang-format makes [[nodiscard]] attributes format sensibly, we can apply them to several functions within the common library to allow the compiler to complain about any misuses of the functions. --- src/common/bit_field.h | 19 ++++++------------- 1 file changed, 6 insertions(+), 13 deletions(-) (limited to 'src/common/bit_field.h') diff --git a/src/common/bit_field.h b/src/common/bit_field.h index 26ae6c7fc..0f0661172 100644 --- a/src/common/bit_field.h +++ b/src/common/bit_field.h @@ -36,13 +36,6 @@ #include "common/common_funcs.h" #include "common/swap.h" -// Inlining -#ifdef _WIN32 -#define FORCE_INLINE __forceinline -#else -#define FORCE_INLINE inline __attribute__((always_inline)) -#endif - /* * Abstract bitfield class * @@ -142,8 +135,8 @@ public: * containing several bitfields can be assembled by formatting each of their values and ORing * the results together. */ - static constexpr FORCE_INLINE StorageType FormatValue(const T& value) { - return ((StorageType)value << position) & mask; + [[nodiscard]] static constexpr StorageType FormatValue(const T& value) { + return (static_cast(value) << position) & mask; } /** @@ -151,7 +144,7 @@ public: * (such as Value() or operator T), but this can be used to extract a value from a bitfield * union in a constexpr context. */ - static constexpr FORCE_INLINE T ExtractValue(const StorageType& storage) { + [[nodiscard]] static constexpr T ExtractValue(const StorageType& storage) { if constexpr (std::numeric_limits::is_signed) { std::size_t shift = 8 * sizeof(T) - bits; return static_cast(static_cast(storage << (shift - position)) >> @@ -175,7 +168,7 @@ public: constexpr BitField(BitField&&) noexcept = default; constexpr BitField& operator=(BitField&&) noexcept = default; - constexpr operator T() const { + [[nodiscard]] constexpr operator T() const { return Value(); } @@ -183,11 +176,11 @@ public: storage = static_cast((storage & ~mask) | FormatValue(value)); } - constexpr T Value() const { + [[nodiscard]] constexpr T Value() const { return ExtractValue(storage); } - constexpr explicit operator bool() const { + [[nodiscard]] constexpr explicit operator bool() const { return Value() != 0; } -- cgit v1.2.3
