From 7dd009d8656c0f5c1c633f3764746335a6feefa7 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 3 Jan 2014 17:08:10 +0000 Subject: Mark various libm tests with xfail-rounding:ldbl-128ibm. This patch marks various libm tests with xfail-rounding:ldbl-128ibm, where the failures appear to relate to GCC bug 59666 (bad libgcc handling of directed rounding), so as to allow clean libm-test-ulps regeneration without needing to edit out large ulps for various functions manually. Note that this only deals with the cases problematic for ulps regeneration. There are plenty of test failures left that do not affect ulps regeneration - results that are infinities or NaNs but should be finite, or vice versa, and missing and spurious exceptions - which should also be resolved during the release testing period. Tested for powerpc32 (hard float). * math/auto-libm-test-in: Mark various tests with xfail-rounding:ldbl-128ibm. * math/auto-libm-test-out: Regenerated. --- math/auto-libm-test-in | 61 +++++++++++++++++++++++++++++--------------------- 1 file changed, 35 insertions(+), 26 deletions(-) (limited to 'math/auto-libm-test-in') diff --git a/math/auto-libm-test-in b/math/auto-libm-test-in index c09089bc5d..cc2890553d 100644 --- a/math/auto-libm-test-in +++ b/math/auto-libm-test-in @@ -503,8 +503,9 @@ cosh 0x1p-5 cosh 0x1p-20 cosh -1 cosh 50 -cosh max no-test-inline -cosh -max no-test-inline +# GCC bug 59666: results on directed rounding may be incorrect. +cosh max no-test-inline xfail-rounding:ldbl-128ibm +cosh -max no-test-inline xfail-rounding:ldbl-128ibm # Bug 16354: spurious underflow may occur. cosh min spurious-underflow cosh -min spurious-underflow @@ -515,22 +516,23 @@ cosh 0x5.96a7ep+4 cosh 0x5.96a7e8p+4 cosh -0x5.96a7ep+4 cosh -0x5.96a7e8p+4 -cosh 0x2.c679d1f73f0fap+8 -cosh 0x2.c679d1f73f0fcp+8 -cosh -0x2.c679d1f73f0fap+8 -cosh -0x2.c679d1f73f0fcp+8 -cosh 0x2.c679d1f73f0fb624d358b213a7p+8 -cosh 0x2.c679d1f73f0fb624d358b213a8p+8 -cosh -0x2.c679d1f73f0fb624d358b213a7p+8 -cosh -0x2.c679d1f73f0fb624d358b213a8p+8 -cosh 0x2.c5d37700c6bb03a4p+12 no-test-inline -cosh 0x2.c5d37700c6bb03a8p+12 no-test-inline -cosh -0x2.c5d37700c6bb03a4p+12 no-test-inline -cosh -0x2.c5d37700c6bb03a8p+12 no-test-inline -cosh 0x2.c5d37700c6bb03a6c24b6c9b494cp+12 no-test-inline -cosh 0x2.c5d37700c6bb03a6c24b6c9b494ep+12 no-test-inline -cosh -0x2.c5d37700c6bb03a6c24b6c9b494cp+12 no-test-inline -cosh -0x2.c5d37700c6bb03a6c24b6c9b494ep+12 no-test-inline +# GCC bug 59666: results on directed rounding may be incorrect. +cosh 0x2.c679d1f73f0fap+8 xfail-rounding:ldbl-128ibm +cosh 0x2.c679d1f73f0fcp+8 xfail-rounding:ldbl-128ibm +cosh -0x2.c679d1f73f0fap+8 xfail-rounding:ldbl-128ibm +cosh -0x2.c679d1f73f0fcp+8 xfail-rounding:ldbl-128ibm +cosh 0x2.c679d1f73f0fb624d358b213a7p+8 xfail-rounding:ldbl-128ibm +cosh 0x2.c679d1f73f0fb624d358b213a8p+8 xfail-rounding:ldbl-128ibm +cosh -0x2.c679d1f73f0fb624d358b213a7p+8 xfail-rounding:ldbl-128ibm +cosh -0x2.c679d1f73f0fb624d358b213a8p+8 xfail-rounding:ldbl-128ibm +cosh 0x2.c5d37700c6bb03a4p+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh 0x2.c5d37700c6bb03a8p+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh -0x2.c5d37700c6bb03a4p+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh -0x2.c5d37700c6bb03a8p+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh 0x2.c5d37700c6bb03a6c24b6c9b494cp+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh 0x2.c5d37700c6bb03a6c24b6c9b494ep+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh -0x2.c5d37700c6bb03a6c24b6c9b494cp+12 no-test-inline xfail-rounding:ldbl-128ibm +cosh -0x2.c5d37700c6bb03a6c24b6c9b494ep+12 no-test-inline xfail-rounding:ldbl-128ibm cpow 1 0 0 0 cpow 2 0 10 0 @@ -727,21 +729,26 @@ exp10 -36 exp10 305 exp10 -305 # Bug 16284: results on directed rounding may be incorrect. -exp10 4932 xfail-rounding:flt-32 +# GCC bug 59666: results on directed rounding may be incorrect. +exp10 4932 xfail-rounding:flt-32 xfail-rounding:ldbl-128ibm # Bug 16361: underflow exception may be misssing exp10 -4932 missing-underflow:ldbl-96-intel:x86 missing-underflow:ldbl-96-intel:x86_64 # Bug 16284: results on directed rounding may be incorrect. -exp10 1e5 xfail-rounding:flt-32 +# GCC bug 59666: results on directed rounding may be incorrect. +exp10 1e5 xfail-rounding:flt-32 xfail-rounding:ldbl-128ibm exp10 -1e5 # Bug 16284: results on directed rounding may be incorrect. -exp10 1e6 xfail-rounding:flt-32 +# GCC bug 59666: results on directed rounding may be incorrect. +exp10 1e6 xfail-rounding:flt-32 xfail-rounding:ldbl-128ibm exp10 -1e6 # Bug 16284: results on directed rounding may be incorrect. -exp10 max xfail-rounding:flt-32 +# GCC bug 59666: results on directed rounding may be incorrect. +exp10 max xfail-rounding:flt-32 xfail-rounding:ldbl-128ibm exp10 -max exp10 0.75 # Bug 16284: results on directed rounding may be incorrect. -exp10 0x1.348e45573a1dd72cp+8 xfail-rounding:flt-32 xfail-rounding:dbl-64 +# GCC bug 59666: results on directed rounding may be incorrect. +exp10 0x1.348e45573a1dd72cp+8 xfail-rounding:flt-32 xfail-rounding:dbl-64 xfail-rounding:ldbl-128ibm exp2 0 exp2 -0 @@ -768,7 +775,8 @@ expm1 0.75 expm1 50.0 expm1 127.0 expm1 500.0 -expm1 11356.25 +# GCC bug 59666: results on directed rounding may be incorrect. +expm1 11356.25 xfail-rounding:ldbl-128ibm expm1 -10.0 expm1 -16.0 expm1 -17.0 @@ -789,8 +797,9 @@ expm1 -100.0 expm1 -1000.0 expm1 -10000.0 expm1 -100000.0 -expm1 100000.0 -expm1 max +# GCC bug 59666: results on directed rounding may be incorrect. +expm1 100000.0 xfail-rounding:ldbl-128ibm +expm1 max xfail-rounding:ldbl-128ibm expm1 -max expm1 0x1p-2 expm1 -0x1p-2 -- cgit 1.4.1
