Extract Linux-specific portitions of cris-tdep.c to a new file.
This brings in some standard functionality hitherdo missing from the CRIS/CRISv32 port thanks to the new call to gdbarch_init_osabi, as well as clearly showing that there is Linux support for this platform by virtue of the existence of a cris-linux-tdep.c file. 2013-09-06 Ricard Wanderlof <ricardw@axis.com> * Makefile.in (ALL_TARGET_OBS): Add cris-linux-tdep.o. * configure.tgt: Add cris-linux-tdep.o and linux-tdep.o to gdb_target_obs for cris target. * cris-tdep.c (struct gdbarch_tdep): Move to cris-tdep.h. (cris_gdbarch_init): Move calls to set_gdbarch_fetch_tls_load_module_address and set_solib_svr4_fetch_link_map_offsets to cris-linux-tdep.c. Add call to gdbarch_init_osabi. * cris-linux-tdep.c: New file. * cris-tdep.h: New file.
