New Revision: 187962
URL: http://svn.freebsd.org/changeset/base/187962
Log:
Add tests for conj{,f,l}() that I wrote some time ago. These test the
versions in libm, not the gcc builtins.
Added:
head/tools/regression/lib/msun/test-conj.c (contents, props changed)
head/tools/regression/lib/msun/test-conj.t (props changed)
- copied unchanged from r181102,
head/tools/regression/lib/msun/test-csqrt.t
Modified:
