+ * Backtracing functions for ARM.
+ *
+ * This implementation uses the exception unwinding tables provided by
+ * the compiler to unwind call frames. Refer to the ARM Exception Handling ABI
+ * documentation (EHABI) for more details about what's going on here.
+ *
+ * An ELF binary may contain an EXIDX section that provides an index to
+ * the exception handling table of each function, sorted by program
+ * counter address.
+ *
+ * This implementation also supports unwinding other processes via ptrace().
+ * In that case, the EXIDX section is found by reading the ELF section table
+ * structures using ptrace().
+ *
+ * Because the tables are used for exception handling, it can happen that
+ * a given function will not have an exception handling table. In particular,
+ * exceptions are assumed to only ever be thrown at call sites. Therefore,
+ * by definition leaf functions will not have exception handling tables.
+ * This may make unwinding impossible in some cases although we can still get
+ * some idea of the call stack by examining the PC and LR registers.
+ *
+ * As we are only interested in backtrace information, we do not need
+ * to perform all of the work of unwinding such as restoring register
+ * state and running cleanup functions. Unwinding is performed virtually on
+ * an abstract machine context consisting of just the ARM core registers.
+ * Furthermore, we do not run generic "personality functions" because
+ * we may not be in a position to execute arbitrary code, especially if
+ * we are running in a signal handler or using ptrace()!
