Rem WARNING WARNING WARNING: This file needs to have DOS CRLF end-of-line
Rem format, or else stock DOS/Windows shells will refuse to run it.
Rem
Rem This batch file unpacks the GDB distribution while simultaneously
Rem renaming some of the files whose names are invalid on DOS or conflict
Rem with other file names after truncation to DOS 8+3 namespace.
Rem
Rem Invoke like this:
Rem
Rem djunpack gdb-XYZ.tar
Rem
Rem where XYZ is the version number. If the argument includes leading
Rem directories, it MUST use backslashes, not forward slashes.
Rem
Rem The following 2 lines need to be changed with each new GDB release, to
Rem be identical to the name of the top-level directory where the GDB
Rem distribution unpacks itself.
set GDBVER=gdb-5.0
if "%GDBVER%"=="gdb-5.0" GoTo EnvOk
Rem If their environment space is too small, re-exec with a larger one
command.com /e:4096 /c %0 %1
GoTo End
:EnvOk
if not exist %1 GoTo NoArchive
djtar -x -p -o %GDBVER%/gdb/config/djgpp/fnchange.lst %1 > fnchange.tmp
Rem The following uses a feature of COPY whereby it does not copy
Rem empty files. We need that because the previous line will create
Rem an empty fnchange.tmp even if the command failed for some reason.
copy fnchange.tmp junk.tmp > nul
if not exist junk.tmp GoTo NoDjTar
del junk.tmp

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

/* The following functions are provided for software stack checking.
If hardware stack-checking is being used then the code can be
compiled without the PCS entry checks, and simply rely on VM
management to extend the stack for a thread.
The stack extension event occurs when the PCS function entry code
would result in a stack-pointer beneath the stack-limit register
value. The system relies on the following map:
+-----------------------------------+ <-- end of stack block
| ... |
| ... |
| active stack |
| ... | <-- sp (stack-pointer) somewhere in here
| ... |
+-----------------------------------+ <-- sl (stack-limit)
| stack-extension handler workspace |
+-----------------------------------+ <-- base of stack block
The "stack-extension handler workspace" is an amount of memory in
which the stack overflow support code must execute. It must be
large enough to deal with the worst case path through the extension
code. At the moment the compiler expects this to be AT LEAST
256bytes. It uses this fact to code functions with small local
data usage within the overflow space.
In a true target environment We may need to increase the space
between sl and the true limit to allow for the stack extension
code, SWI handlers and for undefined instruction handlers of the
target environment. */

mov ip,sp @ Ensure we can calculate the stack required
@ and fall through to...
__rt_stkovf_split_big:
@ in: sp = current stack-pointer (beneath stack-limit)
@ sl = current stack-limit
@ ip = low stack point we require for the current function
@ lr = return address into the current function
@ fp = frame-pointer
@ original sp --> +----------------------------------+
@ | pc (12 ahead of PCS entry store) |
@ current fp ---> +----------------------------------+
@ | lr (on entry) pc (on exit) |

@ +----------------------------------+
@ | fp (on entry to function) |
@ +----------------------------------+
@ | |
@ | ..argument and work registers.. |
@ | |
@ current sp ---> +----------------------------------+
@
@ The "current sl" is somewhere between "original sp" and "current sp"
@ but above "true sl". The "current sl" should be at least 256bytes
@ above the "true sl". The 256byte stack guard should be large enough
@ to deal with the worst case function entry stacking (160bytes) plus
@ the stack overflow handler stacking requirements, plus the stack
@ required for the memory allocation routines.
@
@ Normal PCS entry (before stack overflow check) can stack 16
@ standard registers (64bytes) and 8 floating point registers
@ (96bytes). This gives a minimum stack guard of 160bytes (excluding
@ the stack required for the code). (Actually only a maximum of
@ 14standard registers are ever stacked on entry to a function).
@
@ NOTE: Structure returns are performed by the caller allocating a
@ dummy space on the stack and passing in a "phantom" arg1 into
@ the function. This means that we do not need to worry about
@ preserving the stack under "sp" even on function return.
@
@ Code should never poke values beneath sp. The sp register
@ should always be "dropped" first to cover the data. This
@ protects the data against any events that may try and use
@ the stack.
SUB ip, sp, ip @ extra stack required for function
@ Add stack extension code here. If desired a new stack chunk
@ can be allocated, and the register state updated suitably.
@ We now know how much extra stack the function requires.
@ Terminate the program for the moment:
