* ------------------------------------------------------------------------- * Disect - © DMA 1994-5 24.11.94 ===================== ======== V1.0: 13 Mar-Oct 94 At times, I thought I'd never get there... ------------------- V1.1: 17.11.94-24.11.94 Well, from my rather affected memory: ----------------------- 1) No longer crashes if disassembly window at hardware registers 2) No longer need to define hundreds of copper addresses one at a time (!) 3) DataStrings allow 'X' in base string 4) Will load executables containing LINE debug/HCLN hunks V1.2: 25.11.94-29.11.94 Got fed up playing Frontier, so... ----------------------- 1) Gave screen a proper menu bar, and menus. ASL menus OK now. 2) Screen is now WB2+, ASL requester is (at last) blue! 3) Disect aware of 'gadtools.library' base address 4) Main window is now WFLG_BACKDROP, so now cannot lose ASL requester window behind it! I remember the day I discovered that one... 5) Key '+' swaps both disassembly windows 6) Symbol Window: LMB on a selected symbol, moves (upper) disassembly window to address of (program) symbol 7) Up & Down arrow gadgets in disassembly windows V1.3: 30.11.94-7.12.94 ---------------------- 1) A bug which made Process crash/caused system corruption on Process termination creeped into V1.1. Dead now... 2) INCBIN Request. Thanks to Mark M for that idea 3) Symbol Window: if press a letter key (with/without) SHIFT key, or '.' key, and if symbols are sorted alphabetically, now moves window to first symbol which begins with that character 4) Improved algorithms for ensuring disassembly windows align themselves to defined program addresses 5) Improved handling of global/local program symbol definition and reference 6) Added an 'about' message 7) When define global program symbol, opens request if causes local program symbols to be corrupted 8) RMB on a local in program symbol area moves disassembly window the local's global symbol V1.4: 7.12.94-11.12.94 ---------------------- 1) When disassemble to file, will concatenate successive DC.X statements to produce (much fewer) lines of source 2) RMB on instruction mnemonic moves PC to instruction 3) Can display addresses normally, or as hunk start offsets 4) Allows hunk offsets in expressions: "[0:64]" 5) Shift key WILL move memory window fast 6) Letters in hex now follow selected case 7) Up/down arrow gadgets in windows repeat if held down 8) Alarm sound when finds search data V1.5: 18.12.94 -------------- 1) RMB on displacement (eg: 'dd(Ax)') moves disass window to EA 2) WB requesters if cannot get resources V1.6: 9.1.95-01.02.95 --------------------- 1) It sometimes missed arrow gadget messages, only responding to them when another IDCMP message occurred which created a signal bit to the message port. This happened if LMB > 4 times quickly on arrow gadgets 2) System DataStrings: now contain 'X' for address pointers, and is now aware of address pointers which point to other system structures 3) System DataStrings: automatic line commenting, and automatic program symbol name definition 4) Allows definition of user address same as previous defined 5) Allows a base offset address to be defined 6) LMB on SEA/DEA text to lock register zoom 7) Auto blank lines preference 8) SS 'Prev' gadget allows offsets from locals if same global 9) Dummy symbol selections can be used as line comment texts 10) Symbol Window now contains a scroller gadget 11) Disect aware of 'mathffp.library' base address 12) Added 'PROCP' reserved symbol name 13) Added Process Grabber, but only tested on A500+ so far 14) Request windows which take an address range: can enter '=', '+X', and ',X' into end address string gadgets 15) Was unable to read any DSCT data file if the file contained no user address structures 16) Could not detect characters between "9" and "A" as invalid in hex numbers input by user 17) Added LMB function in Display Breakpoints request window 18) RMB in memory dump will define base offset address 19) No longer scans executable files to determine project memory sizes, now uses seg list (the things you learn once you get the RKMs...) 20) Data areas defined using system DataStrings now get DF'd as macros 21) During DF, if a program symbol name length exceeds one tab size, then the remainder of the source line will be output using a new line 22) Increased executable file hunk limit V1.7: 2.2.95-20.3.95 -------------------- 1) When RMB on program address or displacement, right ALT will move memory window to the address 2) Memory dump now contains a +/- cycle gadget 3) When filling memory: eg, if filling LONGs, but address range was 31 bytes, Disect would actually write 32 bytes (ie: 8 complete LONGs); also changed FORBID/CLEAR CACHE/PERMIT method (once per byte, instead of once per address range, since very large fills may FORBID for too long); also did this for copy memory 4) Search memory also gives alarm sound when search ends (data not found); source/ASCII searches now match any number of spaces or tabs 5) During DF, if a program address was automatically replaced with a (program) symbol (creating an instruction address), the original address would still be logged as an missing undefined-reference address; by adding a single instruction, this was solved 6) Added Process Menu 'Breakpoint At Active Process PC' function, but I think the world may not like this too much... 7) A new, improved Symbol Selection window... 8) Cute little arrow gadgets in main window to move disassembly windows left and right 9) Disect refused to disassemble movec control registers (unless the upper 4 bits of the opcode extension word were 0) 10) Disect hung when I ungrabbed what I had previously considered to be a safe Process to do this to... it was a very well hidden bug (since I did not realise that by sending a Signal to a Wait()ing Process, a task- switch might/will occur) 11) Added Process memory allocations monitor, & unfreed memory list when Process terminates 12) History buffer no longer limited to only four entries (!) 13) ASL window size and coords now saved as Preferences 14) Can now extract symbols from .gs files 15) Binary files: allows load to a preferred address 16) Disect auto-replaces CUSTOM/CIA addresses with symbols 17) Another bug: if an address register contained a library base address, and was displayed in register window as, eg: 'BASEDOS', then the content of the address would not be displayed 18) Mark M pointed out to me that 'CUSTOM' is defined in 'intuition/preferences.i', but not as $DFF000, so had to rename the same symbol (held within Disect executable file) to 'CUSTOM_BASE' 19) Allows '.x' in expressions for FFP values 20) Fill & Copy Memory: no longer FORBID/CLEAR CACHE/PERMIT 21) LMB on address digits in disass window: if right ALT pressed moves memory window to address (instead of defining a breakpoint) 22) Had a bit of screen corruption (register/memory window) if defined a base offset which caused large offsets to be displayed (eg: '[-$12345678]', which would not fit into 10-chars available for it) 23) Now allows definition of key macros... it's simple, but highly effective, and I'll sleep with a grin on my face tonight! (I will get around to allowing macros to be loaded/saved... eventually) 24) Previously, could not replace references to seglists with program symbols (eg: 'move.l main-4,a0'), so Disect will now do this automatically 25) Grabbing a Process would crash if it's pr_WindowPtr was -1 26) Now replaces 'jsr dd(a6)' with relevant '_LVO' symbols for following libraries: Exec, DOS, Gfx, Int, ASL, GadTools, MathFFP 27) Can no longer define breakpoints outside project memory range 28) MultiBin files load and save, and program 'AllocMultiBin' 29) Request window gadgets now display '_' characters beneath letters equivalent to keyboard controls 30) Now allows definition of a Process's variables memory area (either within Process, or allocated memory), and can define user constant symbols as displacements within this memory (eg: dd(ax)), so that Disect can auto-replace any displacements with relevant constant symbol 31) Disect will now display content of addresses (eg: register window) as program symbols (no longer displays only an address as a program symbol) 32) Found a very obscure bug: if a 'JSR _LVOAllocMem' was ('E') executed (buffered), and if this memory was not freed then when Process terminated, unfreed memory was not listed as 'SELF' allocated 33) Now allows binary files to be inserted into loaded project 34) With much DSCT data (especially on a 500+!), things tended to get slow, so added something to speed things up (although it still seems too slow at times...) 35) Auto Trace mode!! 36) Hardware monitor (not finished?!) V1.8: 21.3.95 ... 10.7.95 ------------------------- 1) Hardware monitor now finished 2) Can now end a key-macro definition with a request window open 3) Key-macros now record menu messages 4) Can save INCBIN areas as IFF ILBMs 5) Added audio sample player 6) Can manually open trackdisk device (for when if have saved a pre-loaded boot block as a multibin file) 7) Disect will now auto-replace ARID references to chip & CIA registers when PC at, eg: ...,dmacon(a4) 8) Can now SET or EQU constant symbols manually 9) Disect now shows possible Process variables memory references using a 'V' marker, and LMB on this will auto-replace 10) Instant definition of BYTE/WORD/LONG Data addresses via LMB 11) Defining data addresses until 'Next Symbol' will now define data area size explicitly, instead of leaving it 'variable' 12) Can now save boot blocks 13) DF now warns of references to addresses in project mem but outside disassemble area(s) 14) DF areas now displayed as (blue?) background in disassembly window 15) DF address range lists can now be loaded and saved 16) Can now 'Run Copper List' 17) Will now remap executable file's Process [hunk:offset] to a corresponding [offset] into the executable file on disk (for when executable is loaded as a binary file...) 18) Will now search user addresses for use of any system/user symbol 19) MultiBin files now allow Process status to be saved. Is only useful for games (ie: does not use OS, probably kills it straight away) since is ?impossible? to save a Process which has eg: opened a screen & 4 windows and half a dozen third-party libraries, set up interrupt servers, ... etc AND restore EVERYTHING when you load it back up later 20) A MultiBin 'file' can consist of more than one file (eg: a 1.5 meg 'file' split across two disks) 21) Two more prefs: maximum MultiBin file size & '.b'/'.s' for branch instructions 22) Bug fixed: did not select copjmp1 or 2 when execute a write to either register 23) Hardware monitor now does (certain) blitter registers 24) Finally removed the (redundant) project request window 25) Can now also define data areas until next -1 byte/word/long 26) Finally fixed the annoying ASL for Mark M 27) Can load/save individual DataStrings 28) DF: user constant EQUs now grouped according to prefix text (ie: any text before a '_' character), and listed in increasing numeric order 29) And system constant EQUs are also 30) Found a bug during DF with spaces (not tabs), which caused corrupt source files when disassembling system structure macros 31) Bug: sometimes, when LMB on an #immediate number which was in project memory range, its value was ignored, resulting in only allowing a symbol selection for a value of zero (this only occurred when #imm was specifically immediate data in an instruction, eg: addi.l #x, as opposed to, say, add.l , where was immediate data 32) Added maximum DF source file size pref 33) Crashed when traced/executed, eg: move.l d0,$4.w, even with hardware monitor enabled; is ok now 34) Hardware monitor now tracks bus error vector instead of odd address vector, since Disect uses odd vec during HWM 35) Previously, did not auto-replace, eg: ...,0(a0), to become ...,ciapra(a0), because EA mode was ARI (not ARID), where '0' was auto done by Disect 36) Now replaces ARIDI references to hardware registers (used to be only ARID references) 37) Will now auto replace the bit number of a btst/bset/bclr/bchg when DEA is CIAA_PRA, CIAB_PRA, or CIAB_PRB (very useful when dissecting disk loaders...) 38) Added stuff to allow a Process to safely alter a7 (hardware menu item 'Stack Top'), and checks if attempt to execute or auto-trace a move to a7 when the address is not in project memory 39) SysSymbol data is now compressed; this saved about 40-50k of disk space 40) Bug fixed: if executed/traced instruction with (conditional) breakpoint at PC, did not suspend at next instruction, only did so when expression was TRUE (it was a loop, fortunately!) 41) Ditto: sometimes got an $80000003 when LMB on the operand of a DC.X which had been defined using a system Data- String 42) Previously, GrabProcess would check the instruction before the rts address from Exec.Wait()/WaitPort(), to ensure it was a jsr _LVO(a6) - this is not always the case, and resulted in not being able to grab certain Processes, so I removed this check 43) DC.L operands: if have matching program symbol, now displays 'P' marker, and can LMB on this for auto-replace 44) Auto-LVOs now also done for jmp dd(a6) as well as jsr dd(a6) 45) Added Task & Process system DataStrings (I wanted them to dissect ExecBase TaskWait list, to see why I couldn't grab SimCity! see #42 above!) 46) Further to #38, I forgot to allow a7 to be changed by an instruction so that the new address is not in project memory, but is in stack memory (!). Then, spent two days allowing for every instruction which would alter a7. By method, this worked by checking if the DEA is a7, but, finally, discovered: exg a7,a0 (a7 is SEA!). What fun this all was (?) 47) In memory window (small one in main screen), if any memory address is within the Process's Process structure, Disect now displays, eg: TC_SPLOWER, or pr_SegList instead of the address (is preference-able: 'Symbolic Address Display') 48) Previously, if I defined a data area using, for example, an LH DataString, but then realised it was an LN, it would not (always) replace the line comments, and it would never replace the program symbol at data area start (which messed up the macros during DF!) 49) During auto-trace, a JMP to a ROM (or external) function would be traced even if you didn`t want it to be, since Disect was only looking for JSR (or BSR!) to ROM/etc 50) Another One! With a grabbed Process, auto-trace mode did not detect a write to stack memory as being a permitted DEA 51) Disect now checks to ensure that TRACE and ILLEGAL vectors are intact before executing anything/anyhow 52) Can now (at last!) display Process's allocated memory (if a memory monitor has been installed) 53) Current project name now displayed in screen title 54) Disect now allows 'address constant' symbols; defined via CTRL key & LMB on 'd0', etc, in register window * ------------------------------------------------------------------------- *
