| 1 : | anton | 1.9 | User-visible changes between 0.5.0 and 0.6.0: |
| 2 : | |||
| 3 : | added words: EDIT-LINE ID. .ID CONST-DOES> K-PRIOR K-NEXT K-DELETE SLURP-FILE SLURP-FID WORDLIST-WORDS | ||
| 4 : | |||
| 5 : | Long word names (512MB on 32-bit systems) are now supported (change to | ||
| 6 : | the header format). | ||
| 7 : | |||
| 8 : | Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the | ||
| 9 : | new capabilities in prims (e.g., automatic handling of the return | ||
| 10 : | stack and instruction stream). | ||
| 11 : | |||
| 12 : | New threaded code execution method: primitive-centric (allows the | ||
| 13 : | following), hybrid direct/indirect threaded (easier portability), | ||
| 14 : | with dynamic superinstructions (typical speedup on Athlon: factor | ||
| 15 : | 2). New engine gforth-itc for dealing with some | ||
| 16 : | backwards-compatibility problems (see "Invoking Gforth" in the | ||
| 17 : | manual). | ||
| 18 : | |||
| 19 : | anton | 1.8 | User-visible changes between 0.4.0 and 0.5.0: |
| 20 : | |||
| 21 : | Changes in behaviour: | ||
| 22 : | |||
| 23 : | There are now two engines: the fast engine (gforth-fast) is at least | ||
| 24 : | as fast as gforth in earlier releases; the debugging engine (gforth) | ||
| 25 : | supports precise backtracing for signals (e.g., illegal memory | ||
| 26 : | access), but is slower by a factor of 1-2. | ||
| 27 : | Block files now start at block 0 by default (instead of block 1). If | ||
| 28 : | you have block files around, prepend 1024 bytes to convert them, or | ||
| 29 : | do a "1 OFFSET !" to establish the old behaviour. | ||
| 30 : | Gforth now does not translate newlines to LFs on reading. Instead, | ||
| 31 : | READ-LINE now interprets LF, CR, and CRLF as newlines. Newlines on | ||
| 32 : | output are in the OSs favourite format. | ||
| 33 : | SEE now disassembles primitives (or hex-DUMPs the code if no | ||
| 34 : | disassembler is available). | ||
| 35 : | >HEAD (aka >NAME) now returns 0 (instead of the nt of ???) on failure. | ||
| 36 : | Syntax of prim changed: stack effects are now surrounded by | ||
| 37 : | parentheses, tabs are insignificant. | ||
| 38 : | |||
| 39 : | Operating environment: | ||
| 40 : | |||
| 41 : | Gforth now produces a backtrace when catching an exception. | ||
| 42 : | On platforms supporting the Unix 98 SA_SIGINFO semantics, you get more | ||
| 43 : | precise error reports for SIGSEGV and SIGFPE (e.g., "stack | ||
| 44 : | underflow" instead of "Invalid memory address"). | ||
| 45 : | Gforth now produces exit code 1 if there is an error (i.e., an | ||
| 46 : | uncaught THROW) in batch processing. | ||
| 47 : | You can use "gforthmi --application ..." to build an image that | ||
| 48 : | processes the whole command-line when invoked directly (instead of | ||
| 49 : | through gforth -i). | ||
| 50 : | |||
| 51 : | Ports: | ||
| 52 : | |||
| 53 : | AIX. | ||
| 54 : | 20% speedup on 604e under powerpc-unknown-linux-gnu, | ||
| 55 : | 19%-29% speedup on Celeron with gcc-2.95. | ||
| 56 : | |||
| 57 : | New words: | ||
| 58 : | |||
| 59 : | Missing ANS Forth words: EKEY EKEY? EKEY>CHAR | ||
| 60 : | Timing words: CPUTIME UTIME | ||
| 61 : | Vector arithmetic: V* FAXPY | ||
| 62 : | FP comparison: F~ABS F~REL | ||
| 63 : | Deferred words: <IS> [IS] | ||
| 64 : | Nested number output: <<# #>> | ||
| 65 : | Exception handling: TRY RECOVER ENDTRY | ||
| 66 : | Directory handling: OPEN-DIR READ-DIR CLOSE-DIR FILENAME-MATCH | ||
| 67 : | Other: ]L PUSH-ORDER | ||
| 68 : | |||
| 69 : | Miscellaneous: | ||
| 70 : | |||
| 71 : | Significant extensions to the manual (added an introduction, among | ||
| 72 : | other things), many of them due to a new team member: Neal Crook. | ||
| 73 : | Added assemblers and disassemblers for 386, Alpha, MIPS (thanks to | ||
| 74 : | contributions by Andrew McKewan, Bernd Thallner, and Christian | ||
| 75 : | Pirker). Contributions of assemblers and disassemblers for other | ||
| 76 : | architectures are welcome. | ||
| 77 : | |||
| 78 : | |||
| 79 : | anton | 1.6 | User-visible changes between 0.3.0 and 0.4.0: |
| 80 : | |||
| 81 : | Operating environment: | ||
| 82 : | |||
| 83 : | Path handling: "." at the start of the path represents the directory | ||
| 84 : | the nearest enclosing file resides in (if there is none: the working | ||
| 85 : | directory). "~+" indicates the working directory. The default path | ||
| 86 : | now has "." in front. | ||
| 87 : | gforth and gforthmi is now more GNU standards compliant (wrt | ||
| 88 : | command-line options). | ||
| 89 : | New command-line-option: --die-on-signal | ||
| 90 : | Errors are now directed to stderr. | ||
| 91 : | Stdout is now unbuffered, if it is a tty. | ||
| 92 : | User input device redirection (for filters) is now possible. | ||
| 93 : | |||
| 94 : | Ports: | ||
| 95 : | |||
| 96 : | Now runs on IRIX (and other MIPS-based systems without linker-flag -d). | ||
| 97 : | Direct threading now works on PowerPC (20% speedup on 604e). | ||
| 98 : | Better support for m68k (thanks to Andreas Schwab and Jorge Acereda). | ||
| 99 : | It is possible to create executables that contain the image (for | ||
| 100 : | non-OS systems). | ||
| 101 : | pazsan | 1.7 | |
| 102 : | Added a lot of embedded control (EC) stuff. Supported controllers and | ||
| 103 : | small CPUs are Siemens C16x, 8086, 6502, Mixed-Mode's FPGA MISC, Bernd Paysan's | ||
| 104 : | 4stack processor. Not finished: ShBoom alias PSC1000, H8, AVR. | ||
| 105 : | anton | 1.6 | |
| 106 : | New, changed, and removed words: | ||
| 107 : | |||
| 108 : | Renamed F0 to FP0 (avoids unexpected behaviour in hex), added aliases | ||
| 109 : | SP0, RP0, LP0 (recommended for future use) for S0, R0, L0. | ||
| 110 : | Renamed PARSE-WORD into SWORD (PARSE-WORD is used with the meaning of | ||
| 111 : | NAME in OpenBoot and dpans6 A.6.2.2008) | ||
| 112 : | Added FPICK (suggested by Julian Noble). | ||
| 113 : | Added EXCEPTION. | ||
| 114 : | S" gforth" ENVIRONMENT? now produces the version-string. | ||
| 115 : | Changed representation of types in struct package, and correspondingly | ||
| 116 : | changed names. | ||
| 117 : | |||
| 118 : | Miscellaneous: | ||
| 119 : | |||
| 120 : | Plain text documentation is now available in doc/gforth.txt. | ||
| 121 : | Documentation improvements. | ||
| 122 : | Wordlist structure changed. | ||
| 123 : | Added mini-oof. | ||
| 124 : | Reorganized files: added directories and reorganized many files into | ||
| 125 : | them; renamed files into 8.3 format to work with completely broken | ||
| 126 : | systems (but there are again some files that won't work there). | ||
| 127 : | Bug fixes. | ||
| 128 : | Various changes without log information only known as mega-patches. | ||
| 129 : | pazsan | 1.7 | Cross compiler now also supports compilation only for undefined or forward |
| 130 : | referenced words. Plugins to support some native code generation | ||
| 131 : | (for PSC1000). | ||
| 132 : | anton | 1.6 | More files in the compat library. |
| 133 : | |||
| 134 : | |||
| 135 : | |||

| 137 : | |||
| 138 : | Stack overflow detection by memory protection on most systems | ||
| 139 : | (allocation with mmap). | ||
| 140 : | gforth.fi is now fully relocatable. | ||
| 141 : | fully relocatable images are now easier to create. | ||
| 142 : | added primitives K and UNDER+. | ||

| 158 : | anton | 1.3 | Portability and Installation: |
| 159 : | |||
| 160 : | anton | 1.1 | Support architectures with buggy long longs (alpha-dec-osf). |
| 161 : | anton | 1.3 | Better support for DOS and other non-Unix systems. |
| 162 : | anton | 1.1 | Size changes through the command line are passed to the image (and |
| 163 : | saved with savesystem); the preamble specifies an interpreter and is | ||
| 164 : | propagated by save-system. | ||
| 165 : | anton | 1.3 | |
| 166 : | Tools: | ||
| 167 : | |||

| 184 : | rewritten to use that mechanism. | ||
| 185 : | |||
| 186 : | Changes to existing words: | ||
| 187 : | |||
| 188 : | EMIT and TYPE now work through file words (and are redirectable). | ||
| 189 : | anton | 1.1 | HEADER now stores the compilation wordlist in the header and REVEAL |
| 190 : | reveals into that wordlist. | ||
| 191 : | anton | 1.3 | changed behaviour of SYSTEM (no longer returns wretval, but puts it in |
| 192 : | $?) added (SYSTEM) ( c_addr u -- wretval wior ). | ||
