#define LLVM_ATTRIBUTE_ALWAYS_INLINE |
LLVM_ATTRIBUTE_ALWAYS_INLINE - On compilers where we have a directive to do so, mark a method "always inline" because it is performance sensitive. GCC 3.4 supported this but is buggy in various cases and produces unimplemented errors, just use it in GCC 4.0 and later.

#define LLVM_BUILTIN_TRAP *(volatile int*)0x11 = 0 |
LLVM_BUILTIN_UNREACHABLE - On compilers which support it, expands to an expression which states that it is undefined behavior for the compiler to reach this point. Otherwise is not defined. LLVM_BUILTIN_TRAP - On compilers which support it, expands to an expression which causes the program to exit abnormally.
Definition at line 282 of file Compiler.h.
#define LLVM_CONSTEXPR |
Definition at line 123 of file Compiler.h.
#define LLVM_DELETED_FUNCTION |
LLVM_DELETED_FUNCTION - Expands to = delete if the compiler supports it. Use to mark functions as uncallable. Member functions with this should be declared private so that some behavior is kept in C++03 mode.
class DontCopy { private: DontCopy(const DontCopy&) LLVM_DELETED_FUNCTION; DontCopy &operator =(const DontCopy&) LLVM_DELETED_FUNCTION; public: ... };
Definition at line 117 of file Compiler.h.
Mark debug helper function definitions like dump() that should not be stripped from debug builds.

#define LLVM_EXPLICIT |

#define LLVM_EXTENSION |
LLVM_EXTENSION - Support compilers where we have a keyword to suppress pedantic diagnostics.

#define LLVM_FUNCTION_NAME __func__ |

Definition at line 355 of file Compiler.h.
#define LLVM_HAS_RVALUE_REFERENCE_THIS 0 |
Does the compiler support r-value reference *this?
Sadly, this is separate from just r-value reference support because GCC implemented everything but this thus far. No release of GCC yet has support for this feature so it is enabled with Clang only. FIXME: This should change to a version check when GCC grows support for it.
Definition at line 79 of file Compiler.h.
#define LLVM_HAS_VARIADIC_TEMPLATES 0 |
Does this compiler support variadic templates.
LLVM_HAS_VARIADIC_TEMPLATES Implies LLVM_HAS_RVALUE_REFERENCES and the existence of std::forward.
Definition at line 89 of file Compiler.h.
#define LLVM_IS_UNALIGNED_ACCESS_FAST 0 |
Is unaligned memory access fast on the host machine.
LLVM_IS_UNALIGNED_ACCESS_FAST Don't specialize on alignment for platforms where unaligned memory accesses generates the same code as aligned memory accesses for common types.
Definition at line 335 of file Compiler.h.
#define LLVM_LIBRARY_VISIBILITY |
LLVM_LIBRARY_VISIBILITY - If a class marked with this attribute is linked into a shared library, then the class should be private to the library and not accessible from outside it. Can also be used to mark variables and functions, making them private to any shared library they are linked into. On PE/COFF targets, library visibility is the default, so this isn't needed.

#define LLVM_LVALUE_FUNCTION |
Expands to '&' if r-value references are supported.
This can be used to provide l-value/r-value overrides of member functions. The r-value override should be guarded by LLVM_HAS_RVALUE_REFERENCE_THIS
Definition at line 99 of file Compiler.h.

__GNUC_PREREQ LLVM_MSC_PREREQ Is the compiler MSVC of at least the specified version? The common
version | values to check for are: 1700: Microsoft Visual Studio 2012 / 11.0 1800: Microsoft Visual Studio 2013 / 12.0 |
