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>

2009-03-16Fixed makefiles inclusion flow to pass actual configuration variable values.Carmelo Amoroso
Test build system modified to be similar to uClibc one: * test custom logic moved from Makefile to a new Makefile.in (to be included by Makefile). * Makefile same for all tests and just used for including all other needed makefiles.
