Currently all target dependent code for s390 is in one file, s390-linux-tdep.c. This includes code general for the architecture as well as code specific for uses in GNU/Linux (user space). Up until now this was OK as GNU/Linux was the only supported OS. In preparation to support the new Linux kernel 'OS' split up the existing s390 code into a general s390-tdep and a GNU/Linux-specific s390-linux-tdep. Note: The record-replay feature will be moved in a separate patch. This is simply due to the fact that the combined patch would be too large for the mailing list. This requires setting the process_record hook during OSABI init to keep the code bisectable. The patch moving record-replay cleans up this hack. gdb/ChangeLog: * s390-linux-nat.c (s390-tdep.h): New include. * Makefile.in (ALL_TARGET_OBS): Add s390-tdep.o. (HFILES_NO_SRCDIR): Add s390-tdep.h.
