Various libm functions have inadequate test coverage in libm-test.inc / auto-libm-test-in - failing to cover all the usual special cases (infinities, NaNs, zero, large and small finite values, subnormals) as well as a reasonable range of ordinary inputs and, where appropriate, inputs close to the thresholds for underflow and overflow. This patch improves test coverage for real functions [a-c]* (with the expectation of adding more coverage for other functions later). Tested x86_64 and x86 and ulps updated accordingly (and eight glibc bugs and one C11 DR filed for issues found in the process). * math/auto-libm-test-in: Add more tests of acos, acosh, asin, asinh, atan, atan2, atanh, cbrt, cos and cosh. * math/auto-libm-test-out: Regenerated. * math/libm-test.inc (acosh_test_data): Add more tests. (atanh_test_data): Likewise. (ceil_test_data): Likewise. (copysign_test_data): Likewise. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise. |
