This contains information to supplement that in the manual.
This is DevpacST Version 2.25
Version 1.9 of the HiSoft File Selector can be found in the FSEL folder.
The .TXT file contains its documentation.
The HiSoft AES path patch program can be found in the AESPATH folder.
The .TXT file contains its documentation.
GenST 2.25
==========
The assembler now supports the operators >=,<=,!=,<> The latter two both
mean 'not equals'.
SECTION directives do not cause the local label to be reset, making it
easier to use them in macros.
\# is now a synonym for NARG in macros.
A mistake involving vq_extnd in GEMMACRO.S has been fixed.
MonST 2.13
==========
This corrects a bug in disassembler of one sort of MOVEM instruction.
MonST 2.10
==========
This corrects a problem introduced in DevpacST 2.22 to do with incorrect
dissasembly of various opcodes.
Editor 1.05
===========
Deleting a line containing the one of the block markers no longer causes
the markers to 'walk' backwards up the text.
Some minor changes were made to scrolling using the vertical scroll arrows.
At the end of line, the delete key may now be used to close up the line if
"wrap" is selected from preferences.
GenST 2.22
==========
INCBIN is no longer padded with a null byte if the file is odd in
length, the even directive should be used after the file if needed.
MonST 2.09
==========
This includes support for disassembly of 68010 instructions and spots
more illegal addressing modes.
Editor 1.04
===========
Scrolling using the vertical scroll arrows works correctly.
When deleting text, the block now 'stays in the same place'.
Editor 1.02
===========
The Find box is wider in medium and high resolution
The load MonST option in preferences now works correctly
The keyboard shortcut for Run is shown correctly (again) on the menu.
Please note that the last two bugs were only present in version 2.20
MonST 2.08
==========
This now gives labels embedded in DATA areas.
Assembler 2.20
==============
Nested macro calls are no longer shown with OPT M-
Listing for DS and BSS now shows the correct address (not that for the
next line)
DC.B import no longer generates a spurious byte
DCB negative number no longer fills up the output device
Optimisations 3 through 7 have been added:
3 absolute addresses will be optimised to short-word addressing
if in the range $FFFF8000-$7FFF inclusive
4 instructions of the form MOVE.L #x,Dn will be optimised to
MOVEQ if x is in the range -128 to 127 inclusive
5 ADD #x and SUB #x instructions will be optimised to Quick forms
if x is in the range 1-8 inclusive
6 not strictly an optimisation; a warning will be issued for each
forward branch that could be made short; this must be used in
conjunction with option type 1
7 convert BRA.S to next instruction to NOP. Formerly this always
occurred even when optimisation was off. It is now an error by
default
The warning messages produced by each optimisation may be individually
controlled, using OPT OWx+ / OPT OWx- where 'x' is the optimising
number (shown above), e.g. OPT OW3+
When using Word- or Long-sized indirection, addresses are checked to be
even, for example MOVE.L 5,A6 will give an error. This may be disabled
if required using OPT E-
The register list syntax produced in earlier MOVEM lists from MonST is
now accepted by GenST.
The | character is now accepted as a bitwise OR operator (for all you C
programmers!)
Symbols set using REG may now be used in expressions, with a warning.
Their value is the same as that used in the MOVEM op.
There is a new option which can be used to detect typing errors, OPT i.
With this on, any indirect, absolute reference will give the error '#
probably missing'. For example, the line
and.b $df,d1
will give an error as and.b #$df,d1 is really intended. This can be
overidden on a line-by-line basis by specifying the expression within
brackets and using .W or .L, for example move.l ($ff8000).L,d0
The '@' character is now allowed in symbols, except when followed by a
digit from 0-7 when it is taken as the start of an octal number. This
is for Lattice C 5 users.
When using the stand-alone version of the assembler it is possible to
define labels on the command-line using the -e option, which should be
followed by one or more assignments, separated by commas or spaces.
Such definitions are parsed as if they were the second line in the
source (i.e. after any options). For example,
genst2 test -e TYPE=4,OUTPUT=1
COMMENT HEAD=expression
This allows the longword in the file header to be set to any particular
value; the default is zero. A value of 1 denotes a fast-loading program
(supported by TOS 1.4 or later) whereby the whole TPA area past the end
of the BSS is not zeroed. This results in decreased loading times on
large memory machines, for those programs that are compatible with it.
HEAD must be in upper-case. Please note that other values are reserved
for future expansion by Atari.
The AESLIB and GEMMACRO files have had form_keybd and form_button added.
The editor no longer displays spurious zeroes in the status line.
Shift-Alt-A assembles without the options dialogue.
Debugger 2.07
=============
Control-W is now Single-Step for the benefit of users with French
keyboards.
The word, long and byte searches can now be made to only look for the
pattern starting on word or long word boundaries. To only search on
word boundaries finish the list of items to search for with ',W'. For
longwords use ',L'. For example:
G W
1234,W
will look for $1234 only on word boundaries.
The Textual and Instruction searches now ask further you wish the
search to be case sensitive. If you press Y then Test will match TEST
or TeSt.
More than 6 conditional breakpoints no longer crashes the help display.
Linker 3.00
===========
LinkST is now the version supplied with Lattice C 5, although the C.LNK
file is still that for version 3.04. Users of Lattice C 5 should use the
C.LNK file supplied with that package.
Assembler 2.09
==============
The AESLIB, VDILIB and GEMMACRO files have been updated for TOS 1.4.
Debugger 2.04
=============
This is now compatible with a wider range of Atari machines.
Linker 2.02
===========
This has a new option, -u (or UPPER in a control file) that upper-cases
all imported and exported symbols.
Assembler 2.08
==============
The new directives TEXT, DATA and BSS are supported for increased
compatibility. They are the same as specifying SECTION xxx.
IMPORTANT: The DCB directive (page 52) now works as described.
Previously the order of the parameters were reversed, so existing code
which relied on the bug will no longer work. Similarly the optimising
numbers in the OPT O directive (page 48) are now implemented as
described. Previously you had to use one less than the documented
numbers.
The LIST + and - directives (page 53) now work exactly as described.
Incorrect divide-by-zero errors on pass 1 no longer occur.
The destination of a MOVE is not allowed to be (PC) relative. Register
equates are allowed in ADDX/SUBX/ABCD/SBCD.
It was possible to crash the editor if a block was deleted and the
cursor was within the block.
The .TTP version now returns a GEMDOS return code to indicate the
success or otherwise of the assembly. Values are:
100 main file not found
20 fatal error
10 error(s)
5 warning(s)
0 OK
The AESLIB.S file has been updated.
Debugger 2.02
=============
The Follow Traps option works on Line A op-codes.
Disassembling with Long-sized data areas works.
The Effective Address display in the register window correctly shows
memory around the stack when in supervisor mode.
Assembler 2.07
==============
A problem with GST sections has been corrected. The editor Delete File
function has been fixed (it was broken in 2.06 only).
Assembler 2.06
==============
The following bugs have been fixed:
type checks on PC-relative with index; FORMAT; IFND/IFD with SET labels.
In addition a new form of local label is supported, denoted with decimal
digits ending with a $ sign, e.g. 1234$. This is to improve compatibility.
The AESLIB.S file has been updated.
Assembler 2.04
==============
The following bugs have been fixed:
GEMDOS MALLOC problem; the optimiser being memory hungry; assembling DRI
code to no-where; low-memory GST output; mixing macros and repeat loops;
INCBIN and odd-length files; INCBIN and ORG together.
INCBIN is now forced to start on an even boundary and is padded with a null
byte if the file is odd in length.
Editor 1.01
===========
There is a new option under Preferences, called End of Line. When
Wrap is selected the cursor behaves differently when you ⇦ or ⇨ past
the ends of a line. Try it and see if you like it.
Assembler 2.02
==============
There is a new option, OPT A+, which enables automatic-PC mode where
possible. For example the line MOVE.L int_in,d0 would get assembled as
MOVE.L int_in(pc),d0. Note that this does not guarantee position-
independent code, but does reduce program size and execution times. It
is used in the GEMTEST program to good effect. This may have to be
overidden (when reading absolute memory for example) and this may be
done by using the (expression).L form, similar to that detailed on page
43 for short word addressing.
There is a new option determining the speed of the assembler, available
in the assembly options dialog box. Under normal circumstances leave the
Fast button selected, but only if the assembler runs out of memory should
you select Slow. This forces the assembler to use as little memory as
possible which slows down disk accesses. It can slow down to a little
faster than GenST Version 1 (which isn't actually that slow!). The .TTP
version may be set to slow mode using the command line option -M.
The assembler can now generate code suitable for linking with OSS Personal
Pascal (Pascal Plus in Germany). For further details please quote your
DevpacST and, if a UK customer, your Pascal serial numbers.
Bugs fixed include the ORG, CNOP, ENDC and REPT directives.
Debugger 2.01
=============
The debugger can now save its Preferences in a MONST2.INF file.
There is a new command, Ctrl-S, that skips the current instruction.
It is equivalent to setting the PC to be x words further on, ideal
for not executing instructions you know are going to produce nasty
results.
The machine may be reset by pressing the combination
Ctrl-Alt-NumericDot when in the debugger. No warning is given.
Linker 2.01
===========
A bug to do with large library files has been corrected.
Source Files 2.01
==================
The GEMTEST, AESLIB, VDILIB and GEMMACRO files have been updated.
Editor 1.00
===========
Not a new feature at all really, we've just never documented it before.
To search and/or replace Tab characters press Ctrl-I in the dialog box
They will be echoed as clock face characters. Ctrl-M must *not* be used
as a substitute for CR. Strange characters, like ① ⇧ and may be
entered by typing a special character, say ?, then using
the Find dialog box to replace it with the required Ctrl- characters.
When using Run Other to run a program you may pass the name of the file
you are currently editing by including a % in the command line, which
will be expanded. A true % may be specified using %%
Assembler 2.00
==============
The default for option M, macro expansions, is OPT M-.
The directive OPT U+ changes local labels start with underlines (_) instead
of periods, to allow code to be generated for the Prospero range of
languages.
In the .TTP version the tab size used when listing may be specified using
the option -Txx, for example -T10.
Debugger 2.00
=============
The command Ctrl-E forces all exceptions to be re-installed. This can be
useful when dealing with compiled programs whose run-times use the
exceptions themselves.
If you enter AMONST2 during the boot sequence you may abort its
installation by quitting with Ctrl-R instead of Ctrl-C.
Please note decimal numbers are now denoted with \, not # as in version 1.
Linker 2.00
===========
An additional directive is allowed in control files:
TRUNCATE
This truncates all symbols to 8 characters, sometimes required to link
assembly language with long labels to compiled code with short labels.
Lattice C 3.04 Users
====================
Supplied is a replacement C.LNK file for use with Lattice C 3.04. Using
it with LINKST will reduce your link times and also reduce your output
file size by using a true BSS-type section. If you use the -n option of
the compiler (page 132) you will be able to specify HiSoft Extended
Debug when linking, allowing longer and more meaningful symbols when
debugging with MonST2.
Manual Corrections
==================
Page 65, the macro expansion at the bottom of the page should show the
binary number as %0110.
Page 156, addr_out consists of longwords, not words.
Page 158, the parameter list to evnt_multi has two missing:
⇩⇩⇩⇩⇩⇩
evnt_multi flags,clicks,mask,bstate,m1flags,m1x,m1y,m1w,m1h,
⇧⇧⇧⇧⇧⇧
⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩⇩
& m2flags,m2x,m2y,m2w,m2h,messagebuf.L,count.L
⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧⇧
Page 94, under Lock Window it should read 'disassembly and memory
windows'
Page 161, under fsel_input, should read 'If D0.W is *zero* on return
then it means'
Page 164, Clear Workstation is v_clrwk, not v_clrwrk
Developer Version
=================
Please note that the Developer version described on Page 180 is not
yet available. If you are interested in it please write to us and your
details will be put on file, you will be then contacted when it is
available.
