s390.c: (s390_expand_builtin): Allow -mhtm to be enabled without -march=zEC12.
2013-07-17 Andreas Krebbel <Andreas.Krebbel@de.ibm.com> * config/s390/s390.c: (s390_expand_builtin): Allow -mhtm to be enabled without -march=zEC12. * config/s390/s390.h (TARGET_HTM): Do not require EC12 machine flags to be set. 2013-07-17 Andreas Krebbel <Andreas.Krebbel@de.ibm.com> * acinclude.m4: Add htm asm check for s390. * configure.tgt: Add -mhtm and -Wa,-march=zEC12 to the options. * configure: Regenerate. * config/s390/target.h: Remove __HTM__ check. (htm_available): Call getauxval to get hwcaps and check whether HTM is available or not. From-SVN: r201004
