ebf45ed0c9 Update bmake glue to build GCC 4.2. 
Also:
        Switch FreeBSD to use libgcc_s.so.1.

        Use dl_iterate_phdr to locate shared objects' exception frame
        info instead of depending on older register_frame_info machinery.
        This allows us to avoid depending on libgcc_s.so.1 in binaries
        that do not use exception handling directly. As an additional
        benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

        Build newly added libgomp.so.1 library, the runtime support
        bits for OpenMP.

        Build LGPLed libssp library. Our libc provides our own
        BSD-licensed SSP callbacks implementation, so this library
        is only built to benefit applications that have hadcoded
        knowledge of libssp.so and libssp_nonshared.a. When linked
        in from command line, these libraries override libc
        implementation.

f85d4141ea Minor Makefile cleanup. Do not use Makefile variables named 'version' and 
'target'. Latter is problematic in particular as apparently FreeBSD's
bsd.prog.mk re-defines it under some circumstances. This causes an
unexpected failures like -dumpmachine not working for cc while working
fine for c++.

Do not re-define IN_GCC in multipe places, it gets inherited from
Makefile.in anyway.

13b4da30e0 Avoid writing uninitialized stack data into a thread's MMX/SSE state by 
first getting the current state with td_thr_getxmmregs_p.  Without this,
debugging a threaded app that uses libthr resulted in kernel panics or
spurious SIGFPEs for me.

(As of revision 1.6, sys/i386/i386/ptrace_machdep.c masks off the
reserved bits in the mxcsr register, which prevents the kernel panics.)

Architectures without PT_GETXMMREGS are not affected.

3c925b07d6 Fix PowerPC-targeted cross-builds performed on 64-bit platforms. 
Only PowerPC supports both 32-bit and 64-bit targets and the
BFD_DEFAULT_TARGET_SIZE is used by the binutils code to reflect
the preferred ABI. We define BFD_DEFAULT_TARGET_SIZE for all
platforms, but based on the build machine. As such 64-bit build
machines defined BFD_DEFAULT_TARGET_SIZE incorrectly for 32-bit
targets, but since this only affects PowerPC it went unnoticed
for a long time.
The fix is to define BFD_DEFAULT_TARGET_SIZE based on the target
architecture.

6a5f85cc03 Remove GNU gzip left-offs, they are no longer necessary. 2007-01-31 03:44:42 +00:00
delphij
2089860135 Replace the GNU gzip with a slightly modified NetBSD gzip. The 
NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.

 - Because this is a piece of mature code and we want to make
   changes so it is added directly rather than importing to
   src/contrib.
 - Connect newly added code to src/usr.bin/ and rescue/rescue
   build.
 - Disconnect the GNU gzip code from build for now, they will
   be eventually removed completely.
 - Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
   WITHOUT_BZIP2.

d05b9c6e82 Add a kluge to allow kgdb(1) to inject its own frame sniffer in the 
list of frame sniffers so that trapframes can be detected. The kluge
is needed because this version of gdb only supports appending a
sniffer to the list of sniffers and the moment kgdb gets a chance to
add its own frame sniffer, the target's default frame sniffer is
already in the list. Since the default frame sniffer claims any
frame thrown at it, kgdb's frame sniffer never gets to smell (a
process much akin to tasting, but with lesser chance of hurling :-)

This commit adds dummy frame sniffers that never claim a frame and
as such don't fix anything yet. However, we now have frame sniffers
and they are being called, so it's just a matter of adding meat to
the bones and we'll be able to properly unwind across trapframes.

b8c1757032 o Remove the obscure tid command, because it does what the thread 
command does, but worse.
o  Remove the obscure proc command, because it does what the thread
   command does, but not unambigously.
o  Move the PID to the extra thread info, where it makes sense and
   where it doesn't confuse users. The extra thread info holds some
   process information, to which the PID belongs.
o  Implement the to_find_new_threads target method by having it call
   the target beneath us if we're not using KVM. This makes sure that
   new threads are found when using the remote target.

o  Fix various core dump scenarios:
   -  Implement the to_files_info target method. Previously the
      'info target' command would cause a NULL pointer dereference.
   -  Don't assume there's a current thread. We're not initialized
      in all cases. This prevents a NULL pointer dereference.
   -  When we're not ussing KVM, have the to_xfer_memory target
      method call the target beneath us. This avoids calling into
      KVM with a NULL pointer.

o  Register a function with atexit(3) to close the KVM object if
   we have one open.
o  Show the unread portion of the kernel's message buffer before
   presenting the prompt. It's bound to provide some useful info.
o  Don't call kgdb_target() twice. It results in having all threads
