| # Dynamic Initialization Guard Library |
| |
| This library provides kernel implementations of C++ compiler callouts |
| for acquiring/releasing static initializer guard variables: |
| * __cxa_guard_acquire |
| * __cxa_guard_release |
| * __cxa_guard_abort |
| |
| The purpose of implementing these functions is to detect, at runtime, |
| the use of function scoped static variables. In development builds |
| (i.e. builds where ZX_DEBUG_ASSERT_IMPLEMENTED is true), calling one |
| of these functions after global constructors have executed will result |
| in a kernel panic. |
