/*
* This file contains test code for ARM kprobes.
*
* The top level function run_all_tests() executes tests for all of the
* supported instruction sets: ARM, 16-bit Thumb, and 32-bit Thumb. These tests
* fall into two categories; run_api_tests() checks basic functionality of the
* kprobes API, and run_test_cases() is a comprehensive test for kprobes
* instruction decoding and simulation.
*
* run_test_cases() first checks the kprobes decoding table for self consistency
* (using table_test()) then executes a series of test cases for each of the CPU
* instruction forms. coverage_start() and coverage_end() are used to verify
* that these test cases cover all of the possible combinations of instructions
* described by the kprobes decoding tables.
*
* The individual test cases are in kprobes-test-arm.c and kprobes-test-thumb.c
* which use the macros defined in kprobes-test.h. The rest of this
* documentation will describe the operation of the framework used by these
* test cases.
