bfd/:
2009-09-07 Tristan Gingold <gingold@adacore.com> * bfd.m4 (BFD_HAVE_TIME_TYPE_MEMBER, BFD_HAVE_SYS_STAT_TYPE_MEMBER): Moved to gas/acinclude.m4 * configure.in: Move tests for tm_gmtoff, st_mtim.tv_sec and st_mtim.tv_nsec to gas/configure.in (bfd_elf64_ia64_vms_vec): Remove vmsutil.lo * configure: Regenerate. * config.in: Regenerate. * vmsutil.c: Moved to gas/config/te-vms.c * vmsutil.h: Removed. * Makefile.am (BFD32_BACKENDS_CFILES): Remove vmsutil.c (BFD32_BACKENDS): Remove vmsutil.lo * Makefile.in: Regenerate. gas/: 2009-09-07 Tristan Gingold <gingold@adacore.com> * Makefile.am (TARG_ENV_CFILES): New variable. Set to te-vms.c (POTFILES): Add $(TARG_ENV_CFILES) in definition. (EXTRA_as_new_SOURCES): Ditto. * Makefile: Regenerate. * acinclude.m4 (BFD_HAVE_TIME_TYPE_MEMBER, BFD_HAVE_SYS_STAT_TYPE_MEMBER): New macro created from bfd/bfd.m4. * configure.in: Add Tests for tm_gmtoff, st_mtim.tv_sec and st_mtim.tv_nsec (from bfd/configure.in). Check for time.h and sys/stat.h headers. Add te-vms.o in extra_objects if te_file is vms. * configure: Regenerate. * config.in: Regenerate. * config/te-vms.c: New file, from bfd/vmsutil.c (vms_dwarf2_file_time_name, vms_dwarf2_file_size_name) (vms_dwarf2_file_name): New functions. (vms_file_stats_name): Make it static, add a dirname parameter to locally create the full pathname. * config/te-vms.h: Add a copyright header. Declare the above functions. (DWARF2_FILE_TIME_NAME, DWARF2_FILE_SIZE_NAME, DWARF2_FILE_NAME): Use the above functions in the definition. * makefile.vms (OBJS): Add te-vms.obj. (te-vms.obj): Create a specific target. * configure.com: Create targ-env.h using a per target value. Compile te-vms.c for ia64.
