stli at linux dot ibm.com <stli at linux dot ibm.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |FIXED --- Comment #14 from stli at linux dot ibm.com <stli at linux dot ibm.com> --- I've tested this patch with help of glibc testsuite. Therefore I've disabled the current workaround: <glibc>/sysdeps/s390/fpu/fix-fp-int-compare-invalid.h: #define FIX_COMPARE_INVALID 0 All tests passed. As information: Without this patch there were fails like: math/test-ldouble-iseqsig.out: testing long double (without inline functions) Failure: iseqsig (-0, qNaN): Exception "Invalid operation" not set Failure: iseqsig (-0, -qNaN): Exception "Invalid operation" not set ... As soon as gcc 10 is released, I will post a glibc-patch which conditionally disables the current workaround. Thanks.
