From 1631ebd26712b2f5f41285c8cada819bebed294c Mon Sep 17 00:00:00 2001 From: Denys Vlasenko Date: Sat, 30 Oct 2010 19:40:35 +0200 Subject: test/math/*: unbreak 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 --- test/Test.mak | 2 ++ 1 file changed, 2 insertions(+) (limited to 'test/Test.mak') diff --git a/test/Test.mak b/test/Test.mak index 43562f2d7..dd3fcc387 100644 --- a/test/Test.mak +++ b/test/Test.mak @@ -74,6 +74,8 @@ define exec_test test -z "$$expected_ret" && export expected_ret=0 ; \ if ! test $$ret -eq $$expected_ret ; then \ echo "ret == $$ret ; expected_ret == $$expected_ret" ; \ + echo "The output of failed test is:"; \ + cat "$(binary_name).out"; \ exit 1 ; \ fi $(SCAT) "$(binary_name).out" -- cgit v1.2.3
