-// Various macros for C++ attributes
+// This header file defines macros for declaring attributes for functions,
+// types, and variables.
+//
+// These macros are used within Abseil and allow the compiler to optimize, where
+// applicable, certain function calls.
+//
// This file is used for both C and C++!
//
// Most macros here are exposing GCC or Clang features, and are stubbed out for
// other compilers.
+//
// GCC attributes documentation:
-// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Function-Attributes.html
-// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Variable-Attributes.html
-// https://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Type-Attributes.html
-//
-// Most attributes in this file are already supported by GCC 4.7.
-// However, some of them are not supported in older version of Clang.
-// Thus, we check __has_attribute() first. If the check fails, we check if we
-// are on GCC and assume the attribute exists on GCC (which is verified on GCC
-// 4.7).
-//
-// For sanitizer-related attributes, define the following macros
-// using -D along with the given value for -fsanitize:
-// - ADDRESS_SANITIZER with -fsanitize=address (GCC 4.8+, Clang)
-// - MEMORY_SANITIZER with -fsanitize=memory (Clang)
-// - THREAD_SANITIZER with -fsanitize=thread (GCC 4.8+, Clang)
-// - UNDEFINED_BEHAVIOR_SANITIZER with -fsanitize=undefined (GCC 4.9+, Clang)
-// - CONTROL_FLOW_INTEGRITY with -fsanitize=cfi (Clang)
-// Since these are only supported by GCC and Clang now, we only check for
-// __GNUC__ (GCC or Clang) and the above macros.

+// Sanitizer Attributes
+// -----------------------------------------------------------------------------
+//
+// Sanitizer-related attributes are not "defined" in this file (and indeed
+// are not defined as such in any file). To utilize the following
+// sanitizer-related attributes within your builds, define the following macros
+// within your build using a `-D` flag, along with the given value for
+// `-fsanitize`:
+//
+// * `ADDRESS_SANITIZER` + `-fsanitize=address` (Clang, GCC 4.8)
+// * `MEMORY_SANITIZER` + `-fsanitize=memory` (Clang-only)
+// * `THREAD_SANITIZER + `-fsanitize=thread` (Clang, GCC 4.8+)
+// * `UNDEFINED_BEHAVIOR_SANITIZER` + `-fsanitize=undefined` (Clang, GCC 4.9+)
+// * `CONTROL_FLOW_INTEGRITY` + -fsanitize=cfi (Clang-only)
+//
+// Example:
+//
+// // Enable branches in the Abseil code that are tagged for ASan:
+// $ bazel -D ADDRESS_SANITIZER -fsanitize=address *target*
+//
+// Since these macro names are only supported by GCC and Clang, we only check
+// for `__GNUC__` (GCC or Clang) and the above macros.
