- Bug fixes and enhancements since Revision 471a (ASM-One V1.47)
-
- Revision 482
- ------------
-
- - ASM-One V1.48 Public Release (31-12-2002)
-
-
- Revision 481
- ------------
-
- - There is no Memory Directory at the moment
-
- - Fixed file size in 'V' command (now shows up to 999 Mb
- instead of only 999 Kb).
-
- - Cleaned up 'V' output.
-
- - 'V' will now always show you the current directory. While
- 'V<path>' will show you the contents of the <path>
- specified.
-
- Previously ASM-One would mixup things which made the 'V'
- directive not very usefull to use..
-
-
- Revision 480
- ------------
-
- - FRxx was never allowed.
-
- Fixed now...
-
- - The mtspr opcode was not recognized.
-
- Fixed..
-
- - ASM-One's PPC register support was (to put it nicely) weak !!
-
- Only a selected few where actualy recognized as PPC registers,
- the rest gave errors. I don't understand why I didn't test
- this before releasing V1.47 and claiming to have PPC support ??
-
- However, all these bugs have been fixed...
-
- - Rearranged new PPC errors.
-
- - Added PPC Errors to the ASM-One Guide.
-
- - General PPC/FPU/AltiVec Registers allowed numbers between
- 0 and 39. Now only between 0 and 31.
-
- - GPRxx and FPRxx where never allowed !!!
-
- Fixed now.
-
- - Forgot to clear the AA and LK bit when disassembling the
- (conditional)branch opcodes.
-
- - When disassembling, all general PPC registers and most numbers
- under 40 where always zero !!
-
- Not anymore..
-
- - Edited some of the PPC Errors.
-
- - Branch instructions used the wrong offset for calculating
- the relative branch.
-
- Fixed now...
-
- - BO and BI where never allowed to be numbers.
-
- Fixed now..
-
-
- Revision 479
- ------------
-
- - Added PPC specific assembling errors.
-
-
- Revision 478
- ------------
-
- - Fixed the Write Link in combination with XDEF problem..
-
-
- Revision 477
- ------------
-
- - FPU opcodes with Byte as immediate operand could never be debugged
- since the byte size was never recognized by the debugger.
-
- This had no effect on the assembly or disassembly of the opcode and
- thus NEVER on the generated executable !!!
-
- - A FPU EQUate will show up as being a '- FPU EQU -' in the symbol
- list.
-
- - Added EQUates with FPU sizes:
-
- EQUS = Single
- EQUD = Double
- EQUX = Extended
- EQUP = Packed
-
- Also, FPU opcodes now work with EQU's (set, =) if the size
- of the opcode is not Byte, Word or Longword, but the value size is.
-
- Example 1:
-
- hello: equ 1
-
- a: fmove.s #hello,fp0
- rts
-
- Example 2:
-
- hello: equs 5.5
-
- a: fmove.s #hello,fp0
- fmove.d #hello,fp1
- rts
-
- Note: As you can see, you can use a value defined as a Single as
- a Double in the opcode. ASM-One will save the value as Single if
- you used EQUS, and ASM-One will restore this value when parsing
- the opcode. But when the actual code is written, the value will be
- written as the size defined by the opcode (in the above example
- as Double) !!
-
- Another Note: ASM-One is allocating extra memory for the FPU Data
- that is generated during an Assembly run. The size of the allocated
- memory is expanded if that's needed.
-
- Every Assembly run the memory is cleared (that is, we start at 0).
-
- The memory is only Freeed when you quite or restart ASM-One.
-
- I've chosen this method to prevent memory defragmentation. Typically
- the extra memory will only be allocated when you use EQUS, EQUD, EQUX
- and/or EQUP. If you never use them, no extra memory will be allocated.
-
-
- Revision 476
- ------------
-
- - The MOVEM routines in combination with REG and EQUR where much
- to complex.
-
- - Removed OPT directive
-
- - When debugging, the disassembled line was never cleared so sometimes
- disassembled stuff from the previous line was still visable.
- (RTG Only)
-
- - Filename was only changed when a sources was read or written ?
-
- - When swapping to an empty source, the current dir will be set to
- the StartUp Dir !!!!
-
- - Directories where not properly initialized when swapping the source.
-
-
- Revision 475
- ------------
-
- - FMOVEM was assembled wrong (mode and registerlist where mixed up).
-
- - During debugging, FPU output was never updated.
-
- - Debug registers have been moved below the source instead of beside it.
- This is only true when in RTG mode...
-
- - PPC instructions b, ba, bc, bca, bcl, bcla, bl and bla where never
- correctly assembled because the operands wher never examined !!
-
- - Fixed badly visable cursor in menubar (during searching, etc.)
-
-
- Revision 474
- ------------
-
- - When using the BLOCK function 'Registers', the menubar was left
- blanc. So you could never see the results.
-
- Fixed now
-
-
- Revision 473
- ------------
-
- - Fixed a bug that 'V' complained about an invalid directory. ASM-One
- now takes the Current Directory.
-
- - Fixed a bug that when doing 'V<directory-name>' ASM-One would take that
- directory as the new Current Directory (this should only happen when
- u use 'V <directory-name>')
-
- - Fixed a bug that when using 'V' ASM-One would update your current source
- in the wrong directory (ideal for losing files or filling up your HD B-)
-
- - Fixed a bug that ASM-One would write to the wrong directory. It would
- write to the last directory accessed with V, W or R regardless of what
- the current source was.
-
- Source swapping works now correct for these directories.
-
- - Fixed a bug that sometimes ASM-One updated a file (when using U)
- because it thought the file was gone (which was not the case).
-
- This only happend when the directory you where in was not the
- same directory as where the source was u loaded.
-
- - Fixed problems with new Directories
-
- ASM-One has now 5 different directories and Filenames.
- They are as follows:
-
- Dir/File Buffer 1:
- ReadSource, WriteSource, WriteBlock, InsertSource
-
- Dir/File Buffer 2:
- ReadBinary, WriteBinary
-
- Dir/File Buffer 3:
- ReadObject. WriteObject, WriteLink
-
- Dir/File Buffer 4:
- WritePreferences, ReadPreferences
-
- Dir/File Buffer 5:
- DirectOutput, WriteProject, ReadProject
-
- Dir/File Buffer 1 is saved when you switch to another source.
-
- Except for Buffer 1, the other buffers only work when using
- the requester, a direct command (examp.: RB <filename>) will
- not set any buffers.
-
- The reason for this is that it's probaly to difficult to remember
- 5 different locations. And since the 'V' command only works with
- Buffer 1, you can't check where a Buffer is pointing too using
- a direct command.
-
- - When you break off a Source Read/Write (or when it fails), the source
- name will no longer change in the Sources Menu or in the Title bar.
-
- - Rewrote Startup Directory related stuff
-
- - Rewrote Requester Routines to use new file/directory buffers
-
- - Changed directory structure (5 directories instead of only 3)
-
-
- Revision 472
- ------------
-
- - Removed some lines of coding in the CD (Create Directory)
- routine
-
- - Commenting and cleaning up of the source
-
-
- Revision 471b-c
- ---------------
-
- - Canceling the Screen Requester could exit ASM-One in
- some cases.
-
- - Removed some lines of coding in the ADD and SUB
- parser routines.
