Andreas Krebbel a4c6bd0821 S/390: libatomic: Fix 16 byte atomic exchange ... The compiler builtin will use the hardware instruction cdsg if the memory operand is properly aligned and will fall back to the library call otherwise. In case the compiler for one part is able to detect that the location is aligned and fails to do so for another usage of the hw instruction and the sw fall back would be mixed on the same memory location. To avoid this the library fall back also has to use the hardware instruction if possible. libatomic/ChangeLog: 2018-03-09 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/exch_n.c: New file. * configure.tgt: Add the config directory for s390.
