problems than it fixes.
* hppa-tdep.c (skip_prologue): If we exit the main loop without
finding all the register saves, retry again without looking for
the registers we could not find the first time.
Better fix for 7768.
calls "main" directly.
(skip_prologue): Always assume arguments were saved into the stack
since GCC will do so without setting the magic Args_Saved bit in
the unwind descriptor.
* config/rs6000/xm-rs6000.h (FIVE_ARG_PTRACE): Likewise.
So we can build under aix4 with an ansi compiler (should not effect aix3
since aix3 doesn't have a ptrace prototype).
of aix4 need different handling than aix3.
* configure: Updated.
* config/powerpc/{aix4.mh,aix4.mt,tm-ppc-aix4.h}: New files
specific to aix4 support on the power pc.
* config/powerpc/tm-ppc-aix.h (DONT_RELOCATE_SYMFILE_OBJFILE): Do
not defined. The aix4 specific target files will do that.
* config/rs6000/{aix4,mh,aix4,mt,tm-rs6000-aix4.h}: New files
specific to aix4 support on the rs6000.
* config/rs6000/tm-rs6000.h (CONVERT_FROM_FUNC_PTR_ADDR): Don't
do the conversion if the pointer is not a magic aix function
pointer.
* rs6000-tdep.c: Include objfiles.h and symtab.h.
(is_magic_function_pointer): New function.
* rs6000-tdep.c (skip_prologue): Refine check for frameless
functions. Handle b .+4 emitted by aix4 compilers. Only
allow one load of a minimal toc pointer. Handle aix4 compiler's
code for alloca.
* rs6000-tdep.c (find_toc_address): Report an error if no toc was
found rather than possibly core dumping.
* partial-stab.h: Handle extra field generated by the aix4 compiler
for enumerations.
* stabsread.c (read_enum_type): Likewise.
and target.
(powerpc-*-eabi*): Don't set configdirs.
(powerpcle-*-eabi*0: Likewise.
* configure: Updated.
* rs6000-nat.c (vmap_ldinfo): Don't relocate data addresses
for the main objfile if DONT_RELOCATE_SYMFILE_OBJFILE is
defined.
* config/powerpc/{aix.mh,aix.mh}: Host and target makefile fragments
for powerpc running aix4.
* config/powerpc/{nm-aix.h, tm-ppc-aix.h, xm-aix.h}: Native, target
and host include files for powerpc running aix4.
More of Mike's powerpc work + minor changes.
(SKIP_TRAMPOLINE_CODE): Define.
* alpha-tdep.c (alpha_frame_saved_pc): Use pc_reg field from
frame to find the saved pc register.
(alpha_saved_pc_after_call): Skip over shared library trampoline
before trying to find the saved pc register.
(find_proc_desc): Copy PROC_PC_REG from found proc_desc
to heuristic proc_desc.
(init_extra_frame_info): Initialize pc_reg field in frame.
values whose length is less than the register size for big endian
targets.
* alpha-tdep.c (alpha_extract_return_value,
alpha_store_return_value): Use alpha_convert_register_to_*
to handle functions returning "float" correctly.
read_next_frame_reg to alpha_find_saved_regs, handle saved
floating point registers.
* mips-tdep.c: Move sigtramp handling of saved registers from
read_next_frame_reg to mips_find_saved_regs, handle saved
floating point registers.
* config/mips/tm-irix3.h, config/mips/tm-irix5.h,
config/mips/tm-mipsv4.h (SIGFRAME_FPREGSAVE_OFF): Define.
* sparc-tdep.c (sparc_pc_adjust): Fix check for `unimp'
instruction to handle functions returning structures with
large sizes properly.
and for thread_alive change from a couple weeks ago.
(extended_remote_ops): Declare and define a new target vector
for the extended remote protocol.
(extended_remote_restart): New function to restart the remote
server & process.
(remote_open): Just a stub routine.
(extended_remote_open): New function to start a remote session
using the extended gdb remote protocol.
(remote_open_1): New function containing code common to both
remote_open and extended_remote_open.
(remote_mourn, extended_remote_mourn, remote_mourn_1): Similarly.
(extended_remote_create_inferior): New function for the extended
remote target.
(initialize_remote): Add the extended_remote_ops target vector.
* gdbserver/server.c (main, case '!'): Set extended_protocol.
(main, case 'k'): If the extended protocol is in use, kill the
inferior then start a new one.
(main, case 'R'): New command to restart the remote server and
inferior process. Only supported when using the extended
protocol.
(main, server loop): If the inferior terminates while using the
extended protocol then start a new one. If getpkt fails when
using the extended protocol then exit.
New extended remote gdb protocol support; intended mainly for use with
the gdbserver testing framework that I'll be checking in soon. Also
useful for interactive remote debugging since it supports "run".
