* Move target_signal_from_host, target_signal_to_host, and store_waitstatus from inftarg.c to target.c. procfs needs them. * target.c: Include "wait.h" and <signal.h>. * target.h, infrun.c (proceed), proceed callers: Pass new code TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with enums being treated as unsigned and is cleaner. * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or TARGET_SIGNAL_0. * infcmd.c (signal_command), infrun.c (signals_info): Don't allow user to specify numeric equivalent of TARGET_SIGNAL_DEFAULT.

1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-20/+20
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.
1993-10-27 * fork-child.c (fork_inferior): Set inferior_pid before callingJim Kingdon1-0/+3
init_trace_fun. Move the code which gets us through the shell to new function startup_inferior. * inferior.h: Declare startup_inferior. * procfs.c (procfs_init_inferior), inftarg.c (ptrace_him): Call startup_inferior. * m3-nat.c (m3_trace_him): Call intercept_exec_calls. * config/nm-m3.h: Don't define STARTUP_INFERIOR. * config/i386/tm-i386m3.h, config/ns32k/tm-ns32k.h, config/mips/tm-mipsm3.h: Don't define START_INFERIOR_TRAPS_EXPECTED.
1993-10-22 * Makefile.in (init.c): Generate using the source, not munch. ThisJim Kingdon1-17/+0
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.
