Wide_Characters and Wide_Wide_Characters are incorrectly printed.
Consider for instance:
Medium : Wide_Character := Wide_Character'Val(16#dead#);
Trying to print the value of this variable yields:
(gdb) p medium
$1 = 57005 '["ad"]'
The integer value is correct (57005 = 0xdead), but the character
representation is not, it should be:
$1 = 57005 '["dead"]'
Same for Wide_Wide_Characters.
There were two issues:
(a) The first issue was in ada-valprint, where we were assuming
that character types were 1 byte long;
(b) The second problem was in c-valprint, where we were down-casting
the integer value of the character to type `unsigned char',
causing use to lose all but the lowest byte.
gdb/ChangeLog:
* ada-valprint. (ada_printchar): Use the correct type length
in call to ada_emit_char.
* c-valprint.c (c_val_print): Remove cast in call to LA_PRINT_CHAR.
gdb/ChangeLog:
* ia64-hpux-nat.c (ia64_hpux_fetch_register): Remove trailing
new-line at end of warning message.
(ia64_hpux_store_register): Remove trailing new-line at end of
error message.
* ia64-hpux-tdep.c: Rephrase comment.
* solib-ia64-hpux.c (struct dld_info): Change type of field
dld_flags from "long long" to ULONGEST.
This function is unused, and the default formatting routine does
just fine, I think. On pa-hpux:
[New process 12565, lwp 2513]
[New process 12565, lwp 2514]
So this patch deletes it.
gdb/ChangeLog:
* hpux-thread.c (hpux_pid_to_str): Delete.
This fixes the printing of Wide_Wide_String objects. For instance,
consider:
My_WWS : Wide_Wide_String := " helo";
Before this patch is applied, GDB prints:
(gdb) print my_wws
$1 = " ["00"]h["00"]e"
gdb/ChangeLog:
* ada-valprint.c (ada_emit_char): Remove strange code.
Check that c is <= UCHAR_MAX before passing it to isascii.
(char_at): Do not assume that TYPE_LEN is either 1 or 2.
When interactive-mode is not auto, GDB always uses that setting to
determine whether to act as if the input stream is a terminal or not.
However, this setting should only be honored if the input stream is
the standard input stream. Otherwise, we run into trouble while
source-ing a GDB script, as shown below (on x86_64-linux):
% cat script
print 1
print 2
% gdb -q
(gdb) set interactive-mode on
(gdb) source script
(gdb) print 3
$1 = 3
The lack of output and the fact that the "print 3" command returned
a value saved in $1 (as opposed to $3) indicates that the script was
not even evaluated at all.
gdb/ChangeLog:
* top.c (input_from_terminal_p): Restrict the use of interactive_mode
to the case where instream is stdin.
gdb/testsuite/ChangeLog:
* gdb.base/interact.exp: New testcase.
We have two stacks to deal with on ia64, when making a function call.
The first is the usual stack frame, and the second is the register
stack frame. On ia64-linux, the register frame is setup by adjusting
the BSP register. Unfortunately for us, the HP-UX kernel does not allow
the debugger to change the value of the BSP.
To work around that limitation, the method I am using here is to push
some assembly code on the stack. This assembly code contains, among
other things, a call to the alloc insn, which sets up our frame for us.
An extensive comment in ia64-hpux-tdep.c explains the entire procedure.
Despite this approach, most of the code in ia64-tdep.c which sets up
the function call is still applicable - and only a few things need
to be done differently: For instance, instead of changing the BSP,
we do nothing. We store the parameters at a different location, etc.
So this patch also adjusts the inf-call code in ia64-tdep.c to make it
a little more extensible: I create a new ia64_infcall_ops structure
which allows an ABI to define how the few things that need to be
differentiated.
Another element that turned out to be necessary but is more of a detail
is that the computation of the linkage pointer needs to be handled
specially for symbols inside shared libraries. This is especially
visible when calling malloc, which happens everytime memory needs to
be allocated in inferior memory... The special treatment included
again the necessity to use some routines only available on the host.
So another target object TARGET_OBJECT_HPUX_SOLIB_GOT was created for
that purpose.

* ia64-tdep.h (struct regcache): Forward declare.
(struct ia64_infcall_ops): New struct type.

for inferior function calls to work properly on ia64-hpux.
This fixes unwinding from a thread that is stopped inside a system call.
This can be seen when switching to a thread that is stopped doing a
pthread_cond_wait, for instance...
The comments inside the code should explain what is happening in our
case (the HP-UX exception in the case of system calls): Under certain
circumstances (program stopped inside syscall), the offset to apply to
the current BSP in order to compute the previous BSP is not the usual
CFM & 0x7f.
We parts in this patch:
1. Figuring out that we are stopped inside a syscal: This requires
a TT_LWP_RUREGS ttrace call, which is not directly possible from
ia64-tdep.c. So use defined a new TARGET_OBJECT_HPUX_UREGS object
to request it from the -nat side.
2. Add a gdbarch_tdep method that allows us to change the default
behavior on ia64-hpux, permitting us to have a different "size of
register frame" in that one particular case.
gdb/ChangeLog:
* target.h (enum target_object): Add TARGET_OBJECT_HPUX_UREGS.
* ia64-tdep.h (struct frame_info): forward declaration.
(struct gdbarch_tdep): Add field size_of_register_frame.
* ia64-tdep.c (ia64_access_reg): Use tdep->size_of_register_frame
to determine the size of the register frame.
(ia64_size_of_register_frame): New function.
(ia64_gdbarch_init): Set tdep->size_of_register_frame.
* ia64-hpux-tdep.c: Include "target.h" and "frame.h".
(IA64_HPUX_UREG_REASON): New macro.
(ia64_hpux_stopped_in_syscall, ia64_hpux_size_of_register_frame):
New functions.
(ia64_hpux_init_abi): Set tdep->size_of_register_frame.
* ia64-hpux-nat.c (ia64_hpux_xfer_uregs): New function.
(ia64_hpux_xfer_partial): Add handling of TARGET_OBJECT_HPUX_UREGS
objects.
