Function Documentation

checkasm_get_cpu_flags()

CheckasmCpu checkasm_get_cpu_flags

(

void

)

Get the current active set of CPU flags.

Returns the currently active (masked) set of CPU flags. During test execution, this reflects which CPU features are currently being tested. May be called from within test functions to choose an implementation to test.

Returns

Current CPU feature flags as a bitmask

Note

The returned value changes as checkasm iterates through different CPU feature sets during testing.

Definition at line 122 of file checkasm.c.

checkasm_get_cpu_info()

const CheckasmCpuInfo * checkasm_get_cpu_info

(

void

)

Get the CPU flag currently being tested.

Returns the CheckasmCpuInfo structure for the CPU flag currently being tested, or NULL if testing the baseline configuration with no additional CPU flags.

Returns

Currently active CPU flag info, or NULL

Note

Unlike checkasm_get_cpu_flags(), this only reflects the currently running test, and does not include any information about previously tested CPU flags.

checkasm_list_tests()

void checkasm_list_tests

(

)

Print available tests.

Prints a list of all test functions registered in the configuration. Useful for discovering what tests are available and for use with test pattern filtering.

void checkasm_list_functions

(

config

)

Print available functions within tests.

Prints a detailed list of all functions being tested across all registered tests. Useful for discovering what can be filtered with function patterns.

Parameters

[in]

config

Configuration containing test definitions

Note

This requires executing all tests to gather information about the available functions. During this process, checkasm_check_func() always returns 0 to skip the actual testing. However, any side effects from test functions will still occur, unless properly guarded. In particular, CheckasmTest.init() and CheckasmTest.uninit() will still be executed.

checkasm_run()

int checkasm_run

(

const CheckasmConfig *

config

)

Run all tests and benchmarks matching the specified patterns.

Executes the checkasm test suite according to the configuration. Tests and functions are filtered according to test_pattern and function_pattern if specified. Benchmarks are run if bench is enabled.

Parameters

[in]

config

Configuration structure with all test parameters

Returns

0 on success (all tests passed), negative error code on failure

Note

This is the lower-level entry point. Most users should use checkasm_main() instead, which handles argument parsing.

Warning

This function may override the processor state in subtle ways, including enabling high-precision performance timers, installing signal handlers and configuring the terminal output.

checkasm_should_fail()

int checkasm_should_fail

(

CheckasmCpu

cpu_flags

)

Mark a block of tests as expected to fail.

Marks the following test functions as expected to fail when any of the specified CPU flags are set. Returns whether these functions should be executed.

Parameters

[in]

cpu_flags

CPU flags for which failure is expected (or -1 for all)

Returns

1 if functions should be executed, 0 if they should be skipped

Note

All functions inside such a block must fail, otherwise the whole test will be considered failed. This is used for testing that known-broken implementations are properly detected as broken.

This is not normally useful for end users; it is mainly defined for use inside checkasm's internal test suite.

if (checkasm_should_fail(CPU_FLAG_SSE2)) {
    // This implementation is known to be broken on SSE2
    if (checkasm_check_func(broken_func_sse2, "broken_func")) {
        checkasm_call_new(); // should fail

checkasm_main()

int checkasm_main	(	CheckasmConfig *	config,
		int	argc,
		const char *	argv[] )

Main entry point for checkasm test programs.

Convenience wrapper around checkasm_run() that parses command-line arguments and updates the config accordingly. This is the recommended entry point for most checkasm test programs. Call this from your main() function.

Before calling this function, initialize config with the minimum set of project-specific fields:

• config.cpu_flags: Array of CPU features to test
• config.tests: Array of test functions
• config.cpu: Detected CPU capabilities

Command-line arguments like –bench, –test, –function, –seed, etc. are automatically parsed and applied to the config.

Parameters

[in,out]	config	Configuration structure (will be modified by argument parsing)
[in]	argc	Argument count from main()
[in]	argv	Argument vector from main()

Returns

0 on success, non-zero on failure (suitable for return from main())

int main(int argc, const char *argv[]) {
    CheckasmConfig config = {
        .cpu_flags     = my_cpu_flags,
        .tests         = my_tests,
        .cpu           = my_get_cpu_flags(),
        .set_cpu_flags = my_set_cpu_flags,
    };
    return checkasm_main(&config, argc, argv);
