* Set errno for scalb errors (bug 6803, bug 6804).Joseph Myers2014-03-311-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the default mode of scalb to set errno (bugs 6803 and 6804). Previously, the _LIB_VERSION == _SVID_ mode would set errno but only in some relevant cases, and with various peculiarities (such as errno setting when an exact infinity or zero result arises with an argument to scalb being an infinity). This patch leaves this mode bug-compatible, while making the default mode set errno in accordance with normal practice (so an exact infinity from an infinite argument is not an error, and nor is an exact zero result). gen-libm-test.pl is taught new notation such as ERRNO_PLUS_OFLOW to facilitate writing the tests of errno setting for underflow / overflow in libm-test.inc. Note that bug 6803 also covers scalbn and scalbln, but this patch only addresses the scalb parts of that bug (along with the whole of bug 6804). Tested x86_64 and x86. [BZ #6803] [BZ #6804] * math/w_scalb.c (__scalb): For non-SVID mode, check result and set errno as appropriate. * math/w_scalbf.c (__scalbf): Likewise. * math/w_scalbl.c (__scalbl): Likewise. * math/gen-libm-test.pl (parse_args): Handle ERRNO_PLUS_OFLOW, ERRNO_MINUS_OFLOW, ERRNO_PLUS_UFLOW and ERRNO_MINUS_UFLOW. * math/libm-test.inc (scalb_test_data): Add errno expectations.

Where there were separate functions in libm-test.inc to test a function in each rounding mode, using AUTO_TESTS_* to list the tests for each rounding mode, those are converted to using ALL_RM_TEST (so generally this patch doesn't change the sets of tests run in each rounding mode, except that in various cases special-case tests given directly in libm-test.inc were previously run only for round-to-nearest, and now are run for all rounding modes).

* Test scalbn and scalbln in all rounding modes, add more tests of negative ↵Joseph Myers2014-03-181-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arguments. Continuing the move to systematically testing libm functions in all rounding modes with ALL_RM_TEST, this patch converts the tests of scalbn and scalbln to use that macro. Those tests include cases of underflow and overflow, meaning the expected results depend on the rounding mode. For convenience in writing such tests manually, the patch adds the notation plus_oflow, minus_oflow, plus_uflow and minus_uflow for overflowing / underflowing results of each sign appropriate to the rounding mode being used, and gen-libm-test.pl is made to substitute in the appropriate values. The tests of underflow and overflow are extended to include negative arguments to provide better coverage (otherwise minus_oflow and minus_uflow wouldn't have been used at all). (A subsequent patch will make ldexp use the scalbn tests, as those functions are equivalent for binary floating point.) Tested x86_64 and x86. * math/gen-libm-test.pl (parse_args): Handle plus_oflow, minus_oflow, plus_uflow and minus_uflow in expected results. * math/libm-test.inc (scalbn_test_data): Add more tests of negative arguments. Use plus_oflow, minus_oflow, plus_uflow and minus_uflow. (scalbn_test): Use ALL_RM_TEST. (scalbln_test_data): Add more tests of negative arguments. Use plus_oflow, minus_oflow, plus_uflow and minus_uflow. (scalbln_test): Use ALL_RM_TEST.
* Add libm-test support for per-rounding-mode manually specified results.Joseph Myers2014-03-171-64/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues the libm-test move towards automatic testing of all test inputs in all rounding modes by adding gen-libm-test.pl support for tests specifying results in each rounding mode manually. Previously a TEST_* line could specify arguments and results, or arguments, results and flags. Now there is the option of (arguments, results-rd, flags-rd, results-rn, flags-rn, results-rz, flags-rz, results-ru, flags-ru). This is used to replace the separate arrays of results in each rounding mode for lrint, llrint and rint. (In the case of rint, some tests were only in rint_test_data and needed to have expectations for non-default rounding modes added, which I did manually. In various cases there were slight differences in things such as the ordering of tests in the arrays for each mode.) Tested x86_64 and x86. * math/gen-libm-test.pl (parse_args): Handle results specified for each rounding mode separately. * math/libm-test.inc (lrint_test_data): Merge in per-rounding-mode tests and results from lrint_tonearest_test_data, lrint_towardzero_test_data, lrint_downward_test_data and lrint_upward_test_data.

* Prepare libm-test.inc structures for multi-rounding-mode testing.Joseph Myers2014-03-061-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present, libm-test.inc tests are run in multiple rounding modes by having a separate array for each rounding mode (which might or might not have the same test inputs as the other such arrays), a separate function calling a RUN_TEST_LOOP_* macro over that array, and a separate call to that function in main. The number of functions tested in multiple rounding modes has gradually increased as rounding-mode-specific bugs have been found and fixed in different functions. It would be better to be able to use a single macro call, in a single function, to run tests for a function over all rounding modes, with this being done for all libm functions except in cases where it's deferred until some bugs can be fixed because XFAILing all affected tests would be painful (that's why the full set of pow tests isn't currently run in all rounding modes). This patch helps prepare for that by making the structures storing expected results for tests store results for all four rounding modes. After this patch, the results for all modes are just duplicates, but tests access the appropriate field in the structure, so helping to pave the way for when the fields stop being duplicates and multiple rounding modes can be tested from a single array. Tests might in future specify a single set of results, to be used in all rounding modes; separate results for each rounding mode, specified manually; or use of auto-libm-tests-* to generate results for each rounding mode. Tested x86_64. * math/libm-test.inc (struct test_f_f_data): Move expected results into structure for each rounding mode. (struct test_ff_f_data): Likewise.

* Adjust how gen-auto-libm-tests handles before-rounding/after-rounding cases.Joseph Myers2014-03-061-22/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes gen-auto-libm-tests so that, when generating test results that depend on whether the architecture has before-rounding or after-rounding tininess detection, the :before-rounding or :after-rounding conditions go on the exception / errno flags generated, rather than generating two separate lines in auto-libm-test-out for e.g. flt-32:before-rounding and flt-32:after-rounding. The rationale for this is as follows. It would be desirable for testing a libm function in all rounding modes to require just one function and array in libm-test.inc, not four (or five), with the array of test data including expected results for all rounding modes rather than separate arrays for each rounding mode that also need to repeat all the test inputs. For gen-libm-test.pl to generate data for such an array from auto-libm-test-out, it would be helpful if each (format, test input) pair has exactly four lines in auto-libm-test-out, one for each rounding mode, rather than some rounding modes having just one line and some having two because the exceptions depend on tininess detection. Tested x86_64 and x86. * math/gen-auto-libm-tests.c: Update comment on output format. (output_for_one_input_case): Generate before-rounding and after-rounding information as conditions on output flags not floating-point format. * math/auto-libm-test-out: Regenerated. * math/gen-libm-test.pl (cond_value): New function. (or_cond_value): Use cond_value. (generate_testfile): Handle conditional exceptions.
* Don't include individual test ulps in libm-test-ulps.Joseph Myers2014-03-051-73/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed <https://sourceware.org/ml/libc-alpha/2014-02/msg00670.html>, it doesn't seem particularly useful for libm-test-ulps files to contain huge amounts of data on ulps for individual tests; just the global maximum observed ulps for each function, together with the verification of exceptions, errno and special results such as infinities and NaNs for each test, suffices to verify that a function's behavior on the given test inputs is within the expected accuracy. Removing this data reduces source tree churn caused by updates to these files when libm tests are added, and reduces the frequency with which testsuite additions actually need libm-test-ulps changes at all. Accordingly, this patch removes that data, so that individual tests get checked against the global bounds for the given function and only generate an error if those are exceeded. Tested x86_64 (including verifying that if an ulps value is artificially reduced, the tests do indeed fail as they should and "make regen-ulps" generates the expected changes). * math/libm-test.inc (struct ulp_data): Don't refer to ulps for individual tests in comment.

* Disable libm-test test name beautification for M_* constants.Joseph Myers2013-12-191-17/+0
| | | | | | | | | | | | | | | | | | | | | math/gen-libm-test.pl has code to beautify names of various constants, transforming the source form in libm-test.inc into the version appearing in test names in libm-test-ulps files. This has become decreasingly relevant over time for the M_* constants, first as I changed the test names so only the arguments and not the expected results appeared in them, then as tests have moved to auto-libm-test-* so that automatically generated hex float constants get used instead of M_* in test inputs. This patch removes the beautification for all M_* constants. Tested x86_64 and x86 and ulps updated accordingly. Even the one case where this affected the name in the ulps files will disappear once complex function tests are moved to auto-libm-test-*. * math/gen-libm-test.pl (%beautify): Remove M_* constants. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
