******** Forthmacs 3.0/3.1 Sources ******** level 2.74 hs 15.05.97 3.1/2.74 15.05.97 - StrongARM? is tested on every bootup - Font aware driver is ARM3-ARM7 ready now - disassembler improved/fixed for SWI and MUL,MLA - key? improved for faster switching - close-files is more⇦stable after severe crashes - set-precision fixed - floatval behaving as fconstant object defined - SerialDev drivers are included in devices.serialdev.???.driver - float, defined - fover fixed 3.1/2.73 - experimental version 3.1/2.72 01.04.97 - ?NEGATE and ?DNEGATE test for n2 < 0 correctly - FILL fixed - SAVE-IMAGE resets SET-RELOCATION-BIT in a correct way 3.1/2.71 17.03.97 - new beta-video driver included for testing and comments - save-image doesn't set AUTOFILE? by default - " tests after opening image file - task initialize improved for turnkey applications - Forthmacs$Path includes an explicit path - disassembler bug fixed - line editor for different DEL keys fixed - CTRL-F12 gives an escape interrupt - CLI-calls redirect output, this is read by (more - (MORE improved for CR+LF files as created by redirection 3.1/2.70 26.02.97 - official release with 2.62 fully suported, faster object access implemented - first 8 words in user area are reserved for runtime changing of NEXT used by the new debugger - NEW and more powerfull debugger included - the BUG register objects RR0 RR1 RTOP RSR ... have been renamed to R0 R1 TOP PSR also because of compatibility reasons - the application sheller has again been modified. grrr, that part just gets on my nerves. I just can't figure out when to do a shell-exit. Applications are done ok, but leaving an obey file is not tracked by RISC OS. So far there seems to be no legal&correct&reliable way. Anyway, this only is important when using nested obey scripts. One way to do it would track the appropriate SWIs :-( 3.1/2.62 17.02.97 A complete new IS handler is built in. It knows about LOCALS, all kernel-type objects and multiple-code-field objects as defined in extend/objects.fth. Testing for object method conflict take place at compile time but the actual binding follows a late binding sheme and is also checked. This is implemented ratherstraightforward with almost no speed penalty. Also the decompiler knows about all these objects. - variable 2variable constant 2constant pointer - locals| nuser tuser auser value defer ;CODE doesn't assemble the stack instructions any longer, you can access the parameter address by r0 get-link MOVE has also been fixed, is also has optimized speed in both directions now FLUSH-CACHE-AREA is replaced by SYNC-CACHE for portability See the manual for stack effect HISTORY-EXPECT has been fixed a bug in the search application has been fixed 3.1/2.61 11.02.97 Work is now concentrated on making this Forthmacs port more portable to NetBSD and other platforms. Also register usage will be the same as used in the ARM FirmWorks port for code reusability. This results in: - no rdx register any more; this wasn't a significant advantage anyway - the floating stack pointer is held in a user variable - ip the instruction pointer is redefined as r12 ASSEMBLER is renamed to ARM-ASSEMBLER but you may use ASSEMBLER within a single-target environment. The disassmbler is pure forth code now, better support for non-RISC OS ARM platforms. 3.1/2.60, 03.02.97 No real changes to the program. The main point in releasing this version is the replacement of the !4th launcher by a more powerful Tcl/shade front end. Also many sources have been regrouped/changed for a better developing environment for cross/multi target environments. Most non-portable things have been moved to risc_os. Anyway, the Tcl frontend is improving the desktop situation a lot and i will continue to support that. 3.1/2.50 exception messages have been moved to the risc_os.messages directory. Each territory identifies it's file by the filename, it's the territories number - default is 0 for UK 3.1/2.49, 20.01.97 - COMPARE, CAPS-COMP and COMP now all user the ANS style ( str1 len1 str2 len2 ) stack effects. substring sifting had to be recoded, many sources had to be fixed. - LCC UPC and all words concerning character handling with internationally different character usages use the appropriate territory modules now. - char>ctrl converts a char to it's controlcode, used by CONTROL - DIGIT is internationalized also using digit>char - FIND is internationalized in (FIND) - C" replaced by ANS S" - K included 3.1/2.48, 13.01.97 - conditional compiling bug fixed, new kernel.iftrue - syscall: compiler produced buggy code with dummy registers being top, should be fixed now - also takes up to 10 parameters in registers - (see) does ?cr first for better output - auto file changed 3.1/2.47, 06.01.97 - some small bugs removed - exception messages removed from binaries 3.1/2.46, 27.12.96 - all multitasking functions didn't work in a correct way with the faster loops, shame on me. 3.1/2.45, 20.12.96 - frame stack pointer made unnecessary, used now as a fast loop index 3.1/2.44 - swapping improved and more simple 3.1/2.43 - some kernel primitives have been optimized (number comparing) - (do) (?do) use one memory cycle less 3.1/2.42 - parameter stack increased to 2k words for large apps - showcrash doesn't crash when no error occured 3.1/2.41, 06.12.96 - small/big binaries now available, standard Forthmacs is distributed with 32 file-handlers, the small kernel and kernel/based applications have 8 handlers and 1k instead of 4k filebuffers. - FILE-PROTECTION hold the filetype in the upper 16bit, the lower the acces type 3.1/2.40, 24.11.96 - public release of the debugged SA compatible and somewhat optimized version - m* and um* switch to optimized primitives when possible - StrongARM? is true when a SA cpu is available - RECURSE is included in kernel - FLUSH-CACHE-AREA used whenever securely possible, this speeds up the comiling significantly. 3.1/2.32 - rare StrongARM related problems removed, new version because 2.31 was released and shipped already 3.1/2.31, 18.11.96 - tool.makedisc improved - application swapping in/out synchronizes code - All archives are now zip/deflated instead of tar/gz easier to use with Spark - new simpler page terminal - tested with StrongARM including tools - some kernelheaders added for improved debugging - removed some undocumented terminal functions of the riscos driver, the paged driver will have them. 3.1/2.30 - StrongARM compatible Forthmacs binaries - File$Path is not used permanently 3.1/2.20 - ANS Floating and Floating Extend included 3.1/2.12 - some job files improved - optimized compiles compresses (lit) n (of) adr -> (oflit) n adr - further work on paged terminal output - floating system is included in kernel tasking ... 3.1/2.11,20.08.96 - terminal functions prepared for paged output - decompiler knows about use-actions - @territory alias language included in kernel - ARM floating point assembler included - task switching also sets floating point stack - convert accepts doubles only when point-at-end as suggested in ANS - number conversion uses >NUMBER 3.1/2.10 - loading the autofile is included in (QUIT for improved error trapping - fgetline recoded using -trailing - bug in catch seems to be fixed now - bug in MOVE fixed - bug in [ELSE] fixed 3.1/2.09 - completely new written online help search engine giving manual extractions in html or ascii - pinhole optimizer installed, so far 0= IF 0= WHILE 0= UNTIL now use ?0=BRANCH. metacompiler, compiler and decompiler are fixed - absolut branch addresses - bug in "CAT fixed - html search engine included in the registered-user version - -TRAILING also removes white/hard spaces - terminal initialising is changed 3.1/2.08 - correct auto file - emacs related files moved to a seperate archive 3.1/2.07 - OS_ReadMonotonicTime is used by all timing routines - THROW and CATCH included, handles all stacks and filehandles - all abort" messages and others have been recoded using throw. - exception messages are available in german and english, you may switch by 7 is language -> german - runtime profiler uses seperate timer - [if?????] words redefined a bit more clever - SAVE-STRING is move to the compatible mode file - ABORT" and ABORT have all been re-coded with CATCH&THROW - STRING-LOAD moved to compatible - FIDSTATUS added, telling all filehandlers in use - .BLK is another accepted extension for DOS2RISCOS conversion - file caching using fbuf is improved 3.1/2.06 - INVERT is added - EVAL is renamed to EVALUATE - AT and AT? are renamed to AT-XY and AT-XY? - RP@ included - UNLINK-ALL removes temporary (cold-hook definition - SerialDev drivers are included in risc_os.serialdev.???.driver 3.1/2.05 - ( hopefully ) all places where cpu instructions are assembled and enabled for being executed FLUSH-CACHE instructions are included.
