* tm-rs6000.h (BELIEVE_PCC_PROMOTION): Define, since AIX cc gets
it right.
(aix_framedata): added nosavedpc field.
(SAVED_PC_AFTER_CALL): Don't try to optimize; just call
read_register.
(FRAMELESS_FUNCTION_INVOCATION): Pass second argument of 0.
(FRAME_SAVED_PC): If PC not saved, use SAVED_PC_AFTER_CALL.
* rs6000-tdep.c (skip_prologue): Handle gcc generated stfd
instructions as function_frame_info does. Expand special case of
st r31,-4(r1) to be st r31,NUM(r1), since gcc can generate offsets
other than -4.
(pop_frame): Add 4 rather than sizeof (int) to avoid host
dependence.
(function_frame_info): Set frameless if the function has no frame,
and set nosavedpc if the PC was not saved. Handle gcc generated
stfd 31,-4(31); st 31, -12(31) correctly.
(frameless_function_invocation): New second argument pcsaved; if 0
return whether the function has a frame, if 1 return whether the
function saved PC.
(frame_initial_stack_address): Correct typo: cache registers for
callee_fi, not for fi, (avoids reading garbage memory locations).
* infptrace.c: remove #ifdef USG from around include ptrace.h.
machines without this header should not be compiling this file.
* nm-rs6000.h, rs6000-nat.c: new files for native support.
* rs6000-tdep.c: do not include sys/ptrace.h or sys/reg.h.
* rs6000-xdep.c: removed. all code now in rs6000-nat.c.
* xm-rs6000.h: do not include ptrace.h.
(ATTACH_DETACH, FETCH_INFERIOR_REGISTERS): moved to nm-rs6000.h.
* config/rs6000.mh (XDEPFILES): removed rs6000-xdep.o.
infptrace.o and inftarg.o move to NATDEPFIES.
(NAT_FILE, NATDEPFILES): new macro for native support.
* infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP
here; it is dealt with at a gdb-target-independent level.
* rs6000-tdep.c (single_step): Don't call ptrace, we are a
high toned routine. Fix return type to void.
* 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().
* All GDB files that #include defs.h: Removed stdio.h.
(defs.h): #include stdio.h.
This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion. (n.b.
many configurations don't build for other reasons.)
