- Devpac Amiga 2 Release 2.15
- ============== ============
-
- Although individual program version numbers may vary, the version
- number that should be written on your registration card should be 2.15.
- When requiring technical support or reporting bugs, please be sure to
- also quote the version number of the individual program in question.
-
- Lattice C users should read the LatticeInfo file on this disk. The ARP
- library has been updated since version 2.13.
-
- We have added many new features to Devpac Amiga since version 2.08,
- detailed below:
-
- Editor
- ======
- Shift-Amiga-A assembles without the options requestor.
-
- Shift-Amiga-L loads a file without the ARP requestor for the benefit of
- slow hard-disk users.
-
- A minor problem with RAM cards in high memory was corrected (e.g. on
- the A3000).
-
- Assembler
- =========
- Various bugs have been fixed, including multi-line macro calls, quoted
- section names and BSS sections. In addition it is now possible to pass
- quoted filenames to GenIm2.
-
- Expressions of the form lab1-lab2 are now allowed when lab1 and lab2
- are both in another section (which must be the same section).
-
- 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 (e.g. 68020 users) using OPT E-
-
- The register list syntax produced in MOVEM lists from MonAm is now
- accepted by GenAm.
-
- 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.
-
- If generating executable, absolute code you may specify ORG.W which
- will force all program references to be short-word.
-
- The RORG directive is now supported for compatibility.
-
- There are several new optimisations that the assembler can perform,
- using OPT O. Additional types are:
- 3 Short Word Addressing
- References to absolute addresses in the range 0-7FFF and FFFF8000 to
- FFFFFFFF will be optimised.
- 4 MOVEQ optimising
- Statements of the form MOVE.L <expr>,Dn will be optimised to MOVEQ if
- <expr> is -128 to 127 inclusive.
- 5 Quick Optimising
- Statements of the form ADD # and SUB # will be optimised to ADDQ / SUBQ
- if possible.
- 6 Warning of short branches
- Not strictly an optimisation, OPT OW6+ in combination with OP O1+ will
- give warnings on forward branches that can be made short so you may
- optimise them yourself. 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+
-
- There is a new option which can be used to detect typing errors, OPT i.
- With this on, any indirect, absolute reference (other than location 4)
- 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 (e.g. for hardware register access)
- by specifying the expression within brackets and using .W or .L, for
- example move.l (_ciabase).L,d0
-
- 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,
- genim2 test -l -e TYPE=4,OUTPUT=1
-
- 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 5.0 users.
-
- Shell 1.3 Users: GenIm2 may be made resident. GenAm2/MonAm2 must not be
- made resident as they are not re-entrant.
-
- Debugger
- ========
- Various bugs have been fixed, including disassembling certain BTST
- instructions, the register window display, 68020/030 compatibility,
- Ctrl-T on a breakpoint, symbol character significance, and
- cross-referencing.
-
- All memory is now checked before it is read to ensure it exists.
- Previously any reads of hardware registers (@C00000) or accidental
- reads because of wrap-around could cause nasty crashes. Invalid memory
- is displayed as **
-
- The Alt-O command can be repeated by pressing space after it shows the
- numbers.
-
- The default printer is now nothing, previously it was PRT:
-
- 68020/030 Users: please note the instruction cache is turned off while
- MonAm is loaded to prevent nasty interactions with the debugger. The
- cache is restored to its original state when the debugger terminates.
- Disabling the cache will produce a performance degradation for which we
- can only apologise. Please also note that the Tutorial in section 1.11
- is not valid for these processors because they allow the odd-access
- that is used in the example.
-
- Disk Details
- ============
-
- In order to make space on Disk 1, the following files and directories
- have been deleted:
- Utilities all
- Fonts all except Topaz
- System some
- You can find these files on your original Workbench disk that came with
- your machine.
-
- When using GenAm2 and MonAm2 on PAL machines with external RAM, you may
- sometimes get *two* mouse pointers; one will be the normal Intuition
- pointer, the other will be the custom pointer associated with the
- program you are using. Do not be alarmed - this seems to be a harmless
- bug in Intuition.
-
- The gb keymap has been updated so that the Help key works on A500s.
-
- Last changed: 17 October 1990.
