This patch adds support for x86 LynxOS (tested on LynxOS 5.0).
gdb/gdbserver/ChangeLog:
* lynx-i386-low.c: New file.
* configure.srv: Add handling of i[34567]86-*-lynxos* targets.
Some of the PTRACE_ macros/values were removed in LynxOS 5.x.
Since we have not use them so far, the chances that we will use them
one day are very small. So I decided to delete them.
gdb/gdbserver/ChangeLog:
* lynx-low.c (ptrace_request_to_str): Remove handling for
request values that have been removed in LynxOS 5.x.
This is one of the changes needed in order to build gdbserver on
LynxOS 5.x.
Really interesting: On LynxOS 4.x, there is a #warning when sys/ptrace.h
is used (explaining that ptrace.h will be used instead), whereas this
file was removed from LynxOS 5.x. The contents of sys/ptrace.h on 4.x
(or at least the meat of it):
#if defined(__GNUC__) || defined(__GNUG__)
#if !defined(__NO_INCLUDE_WARN__)
#warning Using <ptrace.h> instead of <sys/ptrace.h>
#endif /* defined(__NO_INCLUDE_WARN__) */
#endif /* defined(__GNUC__) || defined(__GNUG__) */
#include <ptrace.h>
The fix I went for, for now, is to just include <sys/ptrace.h>
unconditionally. I could have done some configury, but we already
have to build with -D__NO_INCLUDE_WARN__ to avoid the warnings
anyway, and that's unvoidable, due to system includes themselves
including the "wrong" header file.
Since <sys/ptrace.h> seems to be the choice that was made for LynxOS,
and since it works to include it on LynxOS 4.x, I think that's the simplest
solution.
gdb/gdbserver/ChangeLog:
* lynx-low.c, lynx-ppc-low.c: Include <sys/ptrace.h> instead of
<ptrace.h>
* corelow.c (core_open): Use target_signal_from_host if CORE_GDBARCH
is NULL.
* fork-child.c (startup_inferior) <resume_signal>: Use enum
target_signal type.
* linux-nat.c (linux_nat_resume): Use target_signal_to_host before
calling strsignal. Use enum target_signal type for saved_signo.
(linux_handle_extended_wait) <signo>: Use enum target_signal type.
(linux_nat_wait_1): Use enum target_signal type for signo. Use
target_signal_to_host before calling strsignal.
* remote-m32r-sdi.c (m32r_wait, m32r_detach): Replace 0 by
TARGET_SIGNAL_0.

* target.c (mywait) <TARGET_WAITKIND_EXITED>: Fix to use INTEGER.

vasprintf and vsnprintf are not available on LynxOS, at least not on
version 4.0.0. This patch updates the configury to import them from
libiberty if not available out of the box.

This patch moves all includes of malloc.h, which were introduced
purely to get access to alloca's declaration, to server.h, next
to the include of alloca.h.
There is one exception: gdbreplay.c, which does not include server.h.
In this case, the include of alloca.h was simply moved up a bit, next
to the include of malloc.h.
gdb/gdbserver/ChangeLog:
* gdbreplay.c: Move include of alloca.h up, next to include of
malloc.h.
* server.h: Add include of malloc.h.
* mem-break.c: Remove include of malloc.h.
* server.c, tracepoint.c, utils.c, win32-low.c: Likewise.
