Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls. This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.
* coffread.c (coff_end_symtab): Cast 2nd arg of complain() to
correct type.
* defs.h (NORETURN): Define away for Lucid compiler.
* remote.c (remote_timer, remote_interrupt): Signal handlers
take one int arg.
* ser-termios.c (serial_write, serial_close): Return whatever
value the write/close call returns, rather than falling off end.
* inferior.h (PTRACE_ARG3_TYPE): Third arg to ptrace is int on
more systems than it is "char *". Define PTRACE_ARG3_TYPE to
default to int.
* infptrace.c, hppabsd-xdep.c, hppahpux-xdep.c, i386-xdep.c,
inferior.h (call_ptrace): Use PTRACE_ARG3_TYPE to declare type
of third arg.
* a68v-xdep.c, arm-xdep.c, convex-xdep.c, hp300ux-xdep.c, infrun.c,
m88k-xdep.c, mach386-xdep.c, mips-xdep.c, os68k-xdep.c, pyr-tdep.c,
pyr-xdep.c, rs6000-xdep.c, sparc-xdep.c, sun3-xdep.c, sun386-xdep.c,
symm-xdep.c, ultra3-xdep.c: Use PTRACE_ARG3_TYPE to cast ptrace
argument 3.
* sparc-xdep.c, a68v-xdep.c (fetch_inferior_registers,
store_inferior_registers): Supply missing fourth argument to
ptrace().
basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
