Reported by a sun . * libc.map: Add _rpc_dtablesize. Reported by Thorsten Kukuk. * db/makedb.c: Exit with error if number of option is incorrect. * math/Makefile (tests): Add test-fenv. * math/test-fenv.c: New file. Test for exception handling functions. Written mainly by Andreas Jaeger. * sysdeps/i386/fpu/fraiseexcpt.c: Correct implementation. * sysdeps/mach/hurd/abi-tag.h: Set tag to 1 for Hurd and kernel compatibility version to 0. Reported by Roland McGrath. 1997-06-27 18:49 Philip Blundell * sysdeps/standalone/brk.c (__NONE_set_memvals): Correct typo. * sysdeps/standalone/arm/bits/errno.h: Add ENOTDIR. * sysdeps/stub/sys/param.h: Add definition of MAX and MIN. 1997-06-27 10:44 Fila Kolodny * sysdeps/mach/hurd/dl-sysdep.c: Make _dl_sysdep_read_whole_file weak. 1997-06-27 00:51 Andreas Schwab * elf/dl-open.c (_dl_open): Check versions of all newly loaded objects, including dependencies. * elf/dl-runtime.c (fixup): Always use version information if available. 1997-06-26 12:25 Andreas Schwab * sysdeps/m68k/bits/nan.h: Renamed from sysdeps/m68k/nan.h. 1997-06-26 11:40 Andreas Schwab * posix/regex.c (DEBUG_POP): Assume parameter to be pointer to int, not pointer to fail_stack_elt_t. (PUSH_FAILURE_POINT): Fix all formats in debugging messages. Fix type of this_reg. (POP_FAILURE_POINT): Likewise. Fix type of failure_id. (re_match_2_internal): Pass NULL, not 0, to PUSH_FAILURE_POINT. 1997-06-27 02:17 Ulrich Drepper * sysdeps/unix/sysv/linux/syscalls.list: Add quotactl. Reported by a sun. * manual/lgpl.texinfo: Update copyright. --- math/test-fenv.c | 164 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 164 insertions(+) create mode 100644 math/test-fenv.c (limited to 'math/test-fenv.c') diff --git a/math/test-fenv.c b/math/test-fenv.c new file mode 100644 index 0000000..55114cc --- /dev/null +++ b/math/test-fenv.c @@ -0,0 +1,164 @@ +/* Test for exception handling functions of libm */ + +#ifndef _GNU_SOURCE +# define _GNU_SOURCE +#endif + +#include +#include +#include +#include + +#include +#include +#include +#include + +/* + Since not all architectures might define all exceptions, we define + a private set and map accordingly. +*/ +#define NO_EXC 0 +#define INEXACT_EXC 0x1 +#define DIVBYZERO_EXC 0x2 +#define UNDERFLOW_EXC 0x04 +#define OVERFLOW_EXC 0x08 +#define INVALID_EXC 0x10 +#define ALL_EXC \ + (INEXACT_EXC | DIVBYZERO_EXC | UNDERFLOW_EXC | OVERFLOW_EXC | \ + INVALID_EXC) + +static int count_errors; + +/* Test whether a given exception was raised. */ +static void +test_single_exception (short int exception, + short int exc_flag, + fexcept_t fe_flag, + const char *flag_name) +{ + if (exception & exc_flag) + { + if (fetestexcept (fe_flag)) + printf (" Pass: Exception \"%s\" is set\n", flag_name); + else + { + printf (" Fail: Exception \"%s\" is not set\n", flag_name); + ++count_errors; + } + } + else + { + if (fetestexcept (fe_flag)) + { + printf (" Fail: Exception \"%s\" is set\n", flag_name); + ++count_errors; + } + else + { + printf (" Pass: Exception \"%s\" is not set\n", flag_name); + } + } +} + +static void +test_exceptions (const char *test_name, short int exception) +{ + printf ("Test: %s\n", test_name); +#ifdef FE_DIVBYZERO + test_single_exception (exception, DIVBYZERO_EXC, FE_DIVBYZERO, + "DIVBYZERO"); +#endif +#ifdef FE_INVALID + test_single_exception (exception, INVALID_EXC, FE_INVALID, + "INVALID"); +#endif +#ifdef FE_INEXACT + test_single_exception (exception, INEXACT_EXC, FE_INEXACT, + "INEXACT"); +#endif +#ifdef FE_UNDERFLOW + test_single_exception (exception, UNDERFLOW_EXC, FE_UNDERFLOW, + "UNDERFLOW"); +#endif +#ifdef FE_OVERFLOW + test_single_exception (exception, OVERFLOW_EXC, FE_OVERFLOW, + "OVERFLOW"); +#endif +} + + +static void +set_single_exc (const char *test_name, int fe_exc, fexcept_t exception) +{ + char str[200]; + + strcpy (str, test_name); + strcat (str, ": set flag, with rest not set"); + feclearexcept (FE_ALL_EXCEPT); + feraiseexcept (exception); + test_exceptions (str, fe_exc); + + strcpy (str, test_name); + strcat (str, ": clear flag, rest also unset"); + feclearexcept (exception); + test_exceptions (str, NO_EXC); + + strcpy (str, test_name); + strcat (str, ": set flag, with rest set"); + feraiseexcept (FE_ALL_EXCEPT ^ exception); + feraiseexcept (exception); + test_exceptions (str, ALL_EXC); + + strcpy (str, test_name); + strcat (str, ": clear flag, leave rest set"); + feclearexcept (exception); + test_exceptions (str, ALL_EXC ^ fe_exc); +} + +static void +fe_tests (void) +{ + /* clear all exceptions and test if all are cleared */ + feclearexcept (FE_ALL_EXCEPT); + test_exceptions ("feclearexcept (FE_ALL_EXCEPT) clears all exceptions", + NO_EXC); + + /* raise all exceptions and test if all are raised */ + feraiseexcept (FE_ALL_EXCEPT); + test_exceptions ("feraiseexcept (FE_ALL_EXCEPT) raises all exceptions", + ALL_EXC); + feclearexcept (FE_ALL_EXCEPT); + + +#ifdef FE_DIVBYZERO + set_single_exc ("Set/Clear FE_DIVBYZERO", DIVBYZERO_EXC, FE_DIVBYZERO); +#endif +#ifdef FE_INVALID + set_single_exc ("Set/Clear FE_INVALID", INVALID_EXC, FE_INVALID); +#endif +#ifdef FE_INEXACT + set_single_exc ("Set/Clear FE_INEXACT", INEXACT_EXC, FE_INEXACT); +#endif +#ifdef FE_UNDERFLOW + set_single_exc ("Set/Clear FE_UNDERFLOW", UNDERFLOW_EXC, FE_UNDERFLOW); +#endif +#ifdef FE_OVERFLOW + set_single_exc ("Set/Clear FE_OVERFLOW", OVERFLOW_EXC, FE_OVERFLOW); +#endif +} + +int +main (void) +{ + fe_tests (); + /* _LIB_VERSION = _SVID;*/ + + if (count_errors) + { + printf ("\n%d errors occured.\n", count_errors); + exit (1); + } + printf ("\n All tests passed successfully.\n"); + exit (0); +} -- cgit v1.1
