Hi! The following test addition has helped me find and fix type conversion issues in QEMU's MIPS hardware emulation. While certainly glibc is not the best place for such tests, I'm proposing them anyway, as it's just an enhancement of tests already present. Tested for several MIPS multilibs, x86, x86_64, PowerPC -m64. * math/basic-test.c (TEST_CONVERT): New macro, renamed from TEST_TRUNC. (convert_dfsf_test, convert_tfsf_test, convert_tfdf_test): New functions, renamed from truncdfsf_test, trunctfsf_test, trunctfdf_test. (convert_sfdf_test, convert_sftf_test, convert_dftf_test): New functions. (do_test): Run all these. diff --git math/basic-test.c math/basic-test.c index 9e9b848..44145a7 100644 --- math/basic-test.c +++ math/basic-test.c @@ -148,7 +148,7 @@ NAME (void) \ check (#FLOAT " isinf (-HUGE_VALx) == -1", isinf (x1) == -1); \ } -#define TEST_TRUNC(NAME, FLOAT, DOUBLE, SUFFIX) \ +#define TEST_CONVERT(NAME, FLOAT, DOUBLE, SUFFIX) \ void \ NAME (void) \ { \ @@ -189,11 +189,14 @@ NAME (void) \ TEST_FUNC (float_test, float, f, FLT_EPSILON, HUGE_VALF) TEST_FUNC (double_test, double, , DBL_EPSILON, HUGE_VAL) -TEST_TRUNC (truncdfsf_test, float, double, ) +TEST_CONVERT (convert_dfsf_test, float, double, ) +TEST_CONVERT (convert_sfdf_test, double, float, f) #ifndef NO_LONG_DOUBLE TEST_FUNC (ldouble_test, long double, l, LDBL_EPSILON, HUGE_VALL) -TEST_TRUNC (trunctfsf_test, float, long double, l) -TEST_TRUNC (trunctfdf_test, double, long double, l) +TEST_CONVERT (convert_tfsf_test, float, long double, l) +TEST_CONVERT (convert_sftf_test, long double, float, f) +TEST_CONVERT (convert_tfdf_test, double, long double, l) +TEST_CONVERT (convert_dftf_test, long double, double, ) #endif int @@ -201,12 +204,15 @@ do_test (void) { float_test (); double_test (); - truncdfsf_test(); + convert_dfsf_test(); + convert_sfdf_test(); #ifndef NO_LONG_DOUBLE ldouble_test (); - trunctfsf_test(); - trunctfdf_test(); + convert_tfsf_test(); + convert_sftf_test(); + convert_tfdf_test(); + convert_dftf_test(); #endif return errors != 0; GrÃÃe, Thomas
