// Ground rules:
|
|
// - C++ run-time should not be used (static CTORs, RTTI, exceptions, static
|
|
// function-scope locals)
|
|
// - All functions/classes/etc reside in namespace __esan, except for those
|
|
// declared in esan_interface_internal.h.
|
|
// - Platform-specific files should be used instead of ifdefs (*).
|
|
// - No system headers included in header files (*).
|
|
// - Platform specific headers included only into platform-specific files (*).
|
|
//
|
|
// (*) Except when inlining is critical for performance.
