Author: alfredo Date: Wed Nov 18 19:23:30 2020 New Revision: 367811 URL: https://svnweb.freebsd.org/changeset/base/367811 Log: msun tests: use standard floating-point exception flags on lrint and fenv tests Some platforms have additional architecture-specific floating-point flags. Msun test cases lrint and test_fegsetenv (fenv) expects only standard flags, so make sure to mask them appropriately. This makes test pass on PowerPC64.
