+ [BZ #19677]
+ * sysdeps/ieee754/ldbl-128ibm/e_remainderl.c
+ (__ieee754_remainderl): Put zero low parts in canonical form.
+ * sysdeps/ieee754/ldbl-128ibm/test-fmodrem-ldbl-128ibm.c: New
+ file. Based on
+ sysdeps/ieee754/ldbl-128ibm/test-fmodl-ldbl-128ibm.c.
+ * sysdeps/ieee754/ldbl-128ibm/test-fmodl-ldbl-128ibm.c: Replace
+ with wrapper round test-fmodrem-ldbl-128ibm.c.
+ * sysdeps/ieee754/ldbl-128ibm/test-remainderl-ldbl-128ibm.c: New

+ * sysdeps/ieee754/ldbl-128ibm/test-remquol-ldbl-128ibm.c:
+ Likewise.
+ * sysdeps/ieee754/ldbl-128ibm/Makefile (tests): Add
