2010-10-30libm: fix rint/scalb testcase failuresDenys Vlasenko
These failures no longer happen: Failure: Test: scalb (2.0, 0.5) == NaN plus invalid exception Failure: Test: scalb (3.0, -2.5) == NaN plus invalid exception Failure: Test: rint (0.5) == 0.0 Failure: Test: rint (1.5) == 2.0 Failure: Test: rint (2.5) == 2.0 Failure: Test: rint (3.5) == 4.0 Failure: Test: rint (4.5) == 4.0 Failure: Test: rint (-0.5) == -0.0 Failure: Test: rint (-1.5) == -2.0 Failure: Test: rint (-2.5) == -2.0 Failure: Test: rint (-3.5) == -4.0 Failure: Test: rint (-4.5) == -4.0 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2010-10-30test/math/*: unbreakDenys Vlasenko
test/math was not running at all, presume it has bit rotted: It was trying to run libm-test.c as if it is a binary. It was looking for libm-test-ulps (file with allowed errors in lower bits) in arch-specific dirs which do not exist in uclibc, as a result wrong file (libm-test.inc) was used instead. Test failure was not showing the error result, user had to fish it out from some .out files. I added libm-test-ulps-ARCH files from recent glibc, this filtered out a lot of false positives. For example, cosf(M_PI_6l * 4.0) ideally should be -0.5, we are getting -0.50000005047356477217, and this isn't a failure (the difference is one lowest bit of mantissa). "make check UCLIBC_ONLY=1 VERBOSE=1" still fails, but not as catastrophically as before. For the record, the failure occurs on the stage where we check 32-bit float functions, these tests fail: Failure: Test: modf (NaN, &x) == NaN Failure: Test: ilogb (NaN) == FP_ILOGBNAN plus exceptions allowed Failure: Test: scalb (2.0, 0.5) == NaN plus invalid exception Failure: Test: scalb (3.0, -2.5) == NaN plus invalid exception Failure: Test: scalb (0, NaN) == NaN Failure: Test: scalb (1, NaN) == NaN Failure: Test: scalb (0, inf) == NaN plus invalid exception Failure: Test: scalb (-0, inf) == NaN plus invalid exception Failure: Test: scalb (1, inf) == inf Failure: Test: scalb (-1, inf) == -inf Failure: Test: scalb (inf, -inf) == NaN plus invalid exception Failure: Test: scalb (-inf, -inf) == NaN plus invalid exception Failure: Test: scalb (1, NaN) == NaN Failure: Test: scalb (0, NaN) == NaN Failure: Test: scalb (inf, NaN) == NaN Failure: Test: pow (1, NaN) == 1 Failure: Test: pow (1, inf) == 1 Failure: Test: pow (-1, inf) == 1 Failure: Test: pow (1, -inf) == 1 Failure: Test: pow (-1, -inf) == 1 Failure: Test: rint (0.5) == 0.0 Failure: Test: rint (1.5) == 2.0 Failure: Test: rint (2.5) == 2.0 Failure: Test: rint (3.5) == 4.0 Failure: Test: rint (4.5) == 4.0 Failure: Test: rint (-0.5) == -0.0 Failure: Test: rint (-1.5) == -2.0 Failure: Test: rint (-2.5) == -2.0 Failure: Test: rint (-3.5) == -4.0 Failure: Test: rint (-4.5) == -4.0 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2009-02-17libm/Makefile.in: reformat the list of wrappersDenis Vlasenko
so that it is easier to modify, sort, etc; use __ in filenames of wrappers which wrap __functions (it may be useful to have function and file names ALWAYS match); remove names of not implemented wrappers (it was generating useless empty .o files). libm/ldouble_wrappers.c: comment out the wrapper which is not compiled anyway test/math/compile_test.c: improve this test, it was optimizing out some calls, and we don't want that. No actual code changes.
