1994-01-18 * config/pa/tm-hppa.h (unwind_table_entry): Use one of theJeff Law1-2/+14
reserved fields to hold a stub unwind entry type. Fix typo. (stub_unwind_entry): New structure for raw stub unwind entries. (stub_unwind_types): The types of stubs we may encounter.

(frame_chain_valid): Likewise. * paread.c (compare_unwind_entries): New function for sorting unwind table entries. (read_unwind_info): Rewrite to remove dependency on host endianness. Read in data from the $UNWIND_END$ subspace which contains linker stub unwind descriptors. Merge that data into the basic unwind table.

1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-9/+9
Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.
1993-10-22 * Makefile.in (init.c): Generate using the source, not munch. ThisJim Kingdon1-2/+3
cleans up all kinds of hassles (which nm to use in munch, etc). The new formatting conventions (mostly already followed) are that the name of the _initialize_* routines must start in column zero, and must not be inside #if. * munch: Removed. * Makefile.in: Remove references to munch. * serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c, alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c, procfs.c, remote-udi.c, ser-go32.c, ultra3-xdep.c, sh-tdep.c, i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c, z8k-tdep.c: Make sure the above conventions are followed. Make sure they are all declared as returning void. Clean up miscellaneous comments and such.
