From 2bd5c6d529e5038f81575d59f3b2d1b36ec2abaa Mon Sep 17 00:00:00 2001 From: Ray Lu Date: Tue, 8 Jan 2019 17:59:03 -0600 Subject: Merge pull request #1450 in HDFFV/hdf5 from ~SONGYULU/hdf5_ray:TRILAB-98-dt_arith-and-cpp_testhdf5-tests to develop * commit 'b02de315b93ac29d2483a91d526b110a25073505': NNSA Tri-LabsTRILAB-98: Another two test cases out. NNSA Tri-Labs TRILAB-98: Taking out a few more test cases. NNSA Tri-Labs TRILAB-98 dt_arith and cpp_testhdf5 tests fail on sierra.llnl.gov: According to the group decision, simply provide a macro to disable some failing test cases on sierra (IBM power9 cpu). All failing cases involve long double data type. --- config/cmake/ConfigureChecks.cmake | 5 +++ config/cmake/ConversionTests.c | 24 +++++++++++ config/cmake/H5pubconf.h.in | 3 ++ configure.ac | 24 +++++++++++ test/dt_arith.c | 81 +++++++++++++++++++++++++++++++++----- 5 files changed, 128 insertions(+), 9 deletions(-) diff --git a/config/cmake/ConfigureChecks.cmake b/config/cmake/ConfigureChecks.cmake index 459346e..c1abeed 100644 --- a/config/cmake/ConfigureChecks.cmake +++ b/config/cmake/ConfigureChecks.cmake @@ -247,6 +247,11 @@ H5ConversionTests (${HDF_PREFIX}_LDOUBLE_TO_LLONG_ACCURATE "Checking IF correctl # H5ConversionTests (${HDF_PREFIX}_LLONG_TO_LDOUBLE_CORRECT "Checking IF correctly converting (unsigned) long long to long double values") # ---------------------------------------------------------------------- +# Set the flag to indicate that the machine can accurately convert +# some long double values +# +H5ConversionTests (${HDF_PREFIX}_DISABLE_SOME_LDOUBLE_CONV "Checking IF the cpu is power9 and cannot correctly converting long double values") +# ---------------------------------------------------------------------- # Check if pointer alignments are enforced # H5ConversionTests (${HDF_PREFIX}_NO_ALIGNMENT_RESTRICTIONS "Checking IF alignment restrictions are strictly enforced") diff --git a/config/cmake/ConversionTests.c b/config/cmake/ConversionTests.c index c2748b2..6d597a0 100644 --- a/config/cmake/ConversionTests.c +++ b/config/cmake/ConversionTests.c @@ -287,3 +287,27 @@ main () #endif +#ifdef H5_DISABLE_SOME_LDOUBLE_CONV_TEST + +#include +#include +#include + +int HDF_NO_UBSAN main(void) +{ + FILE *fp;
