◆ LLVM_GNUC_PREREQ

#define LLVM_GNUC_PREREQ (   maj,
  min,
  patch 
)    0

LLVM_GNUC_PREREQ Extend the default __GNUC_PREREQ even if glibc's features.h isn't available.

Definition at line 59 of file Compiler.h.

◆ LLVM_HAS_RVALUE_REFERENCE_THIS

#define LLVM_HAS_RVALUE_REFERENCE_THIS   0

Does the compiler support ref-qualifiers for *this?

Sadly, this is separate from just rvalue reference support because GCC and MSVC implemented this later than everything else.

Definition at line 86 of file Compiler.h.

◆ LLVM_LIBRARY_VISIBILITY

#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.

Definition at line 108 of file Compiler.h.

◆ LLVM_LIKELY

#define LLVM_LIKELY (   EXPR)    (EXPR)

◆ LLVM_LVALUE_FUNCTION

#define LLVM_LVALUE_FUNCTION

Expands to '&' if ref-qualifiers for *this are supported.

This can be used to provide lvalue/rvalue overrides of member functions. The rvalue override should be guarded by LLVM_HAS_RVALUE_REFERENCE_THIS

Definition at line 96 of file Compiler.h.

◆ LLVM_MEMORY_SANITIZER_BUILD

#define LLVM_MEMORY_SANITIZER_BUILD   0

LLVM_MEMORY_SANITIZER_BUILD Whether LLVM itself is built with MemorySanitizer instrumentation.

Definition at line 378 of file Compiler.h.

LLVM_MSC_PREREQ Is the compiler MSVC of at least the specified version? The common

Parameters
versionvalues to check for are:
  • 1900: Microsoft Visual Studio 2015 / 14.0

Definition at line 76 of file Compiler.h.

◆ LLVM_NO_SANITIZE

LLVM_NO_SANITIZE Disable a particular sanitizer for a function.

Definition at line 442 of file Compiler.h.

◆ LLVM_NODISCARD

LLVM_NODISCARD - Warn if a type or return value is discarded.

◆ LLVM_PACKED

#define LLVM_PACKED (   d)    d __attribute__((packed))

LLVM_PACKED Used to specify a packed structure.

LLVM_PACKED( struct A { int i; int j; int k; long long l; });

LLVM_PACKED_START struct B { int i; int j; int k; long long l; }; LLVM_PACKED_END

#define LLVM_PREFETCH (   addr,

Definition at line 114 of file Compiler.h.

◆ LLVM_PRETTY_FUNCTION

#define LLVM_PRETTY_FUNCTION   __func__

LLVM_PRETTY_FUNCTION Gets a user-friendly looking function signature for the current scope using the best available method on each platform.

The exact format of the resulting string is implementation specific and non-portable, so this should only be used, for example, for logging or diagnostics.

Definition at line 467 of file Compiler.h.

◆ LLVM_PTR_SIZE

#define LLVM_PTR_SIZE   sizeof(void *)

LLVM_PTR_SIZE A constant integer equivalent to the value of sizeof(void*).

Generally used in combination with LLVM_ALIGNAS or when doing computation in the preprocessor.

Definition at line 369 of file Compiler.h.

◆ LLVM_READNONE

#define LLVM_READNONE

◆ LLVM_READONLY

#define LLVM_READONLY

◆ LLVM_THREAD_LOCAL

#define LLVM_THREAD_LOCAL   __thread

LLVM_THREAD_LOCAL A thread-local storage specifier which can be used with globals, extern globals, and static globals.

This is essentially an extremely restricted analog to C++11's thread_local support, and uses that when available. However, it falls back on platform-specific or vendor-provided extensions when necessary. These extensions don't support many of the C++11 thread_local's features. You should only use this for PODs that you can statically initialize to some constant value. In almost all circumstances this is most appropriate for use with a pointer, integer, or small aggregation of pointers and integers.

Definition at line 491 of file Compiler.h.
