User-visible changes between 0.1beta and 0.2.0 |
User-visible changes between 0.6.0 and 0.6.1: |
|
|
|
Bug fixes (installation on big-endian machines sometimes did not work) |
|
|
|
|
|
User-visible changes between 0.5.0 and 0.6.0: |
|
|
|
Changes in behaviour: |
|
|
|
S": interpreted use now ALLOCATEs the string (they live until BYE). |
|
Long word names (512MB on 32-bit systems) are now supported (change to |
|
the header format). |
|
New threaded code execution method: primitive-centric (allows the |
|
following), hybrid direct/indirect threaded (easier portability), |
|
with dynamic superinstructions (typical speedup on Athlon: factor |
|
2). New engine gforth-itc for dealing with some potential |
|
backwards-compatibility problems (see "Direct or Indirect Threaded?" |
|
in the manual). |
|
|
|
Operating environment: |
|
|
|
Default dictionary size is now 4MB. |
|
Large file support on OSs that support them (i.e., files with more |
|
than 2GB on 32-bit machines). |
|
Gforth can now deal well with broken pipes in most situations. |
|
vi tags files can be built with tags.fs (usage like etags.fs). |
|
gforth.el mostly rewritten. |
|
New image file format. |
|
|
|
New words: |
|
|
|
Keyboard input: EDIT-LINE K-PRIOR K-NEXT K-DELETE |
|
File input: SLURP-FILE SLURP-FID |
|
Programming tools: ID. .ID WORDLIST-WORDS SIMPLE-SEE |
|
Conditional execution: [DEFINED] [UNDEFINED] |
|
Defining Words: CONST-DOES> |
|
Input stream: PARSE-WORD EXECUTE-PARSING EXECUTE-PARSING-FILE |
|
String comparison: STR= STR< STRING-PREFIX? |
|
String literals: S\" .\" \"-PARSE |
|
Floating point output: F.RDP F>STR-RDP F>BUF-RDP |
|
|
|
Miscellaneous: |
|
|
|
Generalized prims2x.fs into Vmgen (see README.vmgen etc.); used the |
|
new capabilities in prims (e.g., automatic handling of the return |
|
stack and instruction stream). |
|
|
|
|
|
User-visible changes between 0.4.0 and 0.5.0: |
|
|
|
Changes in behaviour: |
|
|
|
There are now two engines: the fast engine (gforth-fast) is at least |
|
as fast as gforth in earlier releases; the debugging engine (gforth) |
|
supports precise backtracing for signals (e.g., illegal memory |
|
access), but is slower by a factor of 1-2. |
|
Block files now start at block 0 by default (instead of block 1). If |
|
you have block files around, prepend 1024 bytes to convert them, or |
|
do a "1 OFFSET !" to establish the old behaviour. |
|
Gforth now does not translate newlines to LFs on reading. Instead, |
|
READ-LINE now interprets LF, CR, and CRLF as newlines. Newlines on |
|
output are in the OSs favourite format. |
|
SEE now disassembles primitives (or hex-DUMPs the code if no |
|
disassembler is available). |
|
>HEAD (aka >NAME) now returns 0 (instead of the nt of ???) on failure. |
|
Syntax of prim changed: stack effects are now surrounded by |
|
parentheses, tabs are insignificant. |
|
|
|
Operating environment: |
|
|
|
Gforth now produces a backtrace when catching an exception. |
|
On platforms supporting the Unix 98 SA_SIGINFO semantics, you get more |
|
precise error reports for SIGSEGV and SIGFPE (e.g., "stack |
|
underflow" instead of "Invalid memory address"). |
|
Gforth now produces exit code 1 if there is an error (i.e., an |
|
uncaught THROW) in batch processing. |
|
You can use "gforthmi --application ..." to build an image that |
|
processes the whole command-line when invoked directly (instead of |
|
through gforth -i). |
|
|
|
Ports: |
|
|
|
AIX. |
|
20% speedup on 604e under powerpc-unknown-linux-gnu, |
|
19%-29% speedup on Celeron with gcc-2.95. |
|
|
|
New words: |
|
|
|
Missing ANS Forth words: EKEY EKEY? EKEY>CHAR |
|
Timing words: CPUTIME UTIME |
|
Vector arithmetic: V* FAXPY |
|
FP comparison: F~ABS F~REL |
|
Deferred words: <IS> [IS] |
|
Nested number output: <<# #>> |
|
Exception handling: TRY RECOVER ENDTRY |
|
Directory handling: OPEN-DIR READ-DIR CLOSE-DIR FILENAME-MATCH |
|
Other: ]L PUSH-ORDER |
|
|
|
Miscellaneous: |
|
|
|
Significant extensions to the manual (added an introduction, among |
|
other things), many of them due to a new team member: Neal Crook. |
|
Added assemblers and disassemblers for 386, Alpha, MIPS (thanks to |
|
contributions by Andrew McKewan, Bernd Thallner, and Christian |
|
Pirker). Contributions of assemblers and disassemblers for other |
|
architectures are welcome. |
|
|
|
|
|
User-visible changes between 0.3.0 and 0.4.0: |
|
|
|
Operating environment: |
|
|
|
Path handling: "." at the start of the path represents the directory |
|
the nearest enclosing file resides in (if there is none: the working |
|
directory). "~+" indicates the working directory. The default path |
|
now has "." in front. |
|
gforth and gforthmi is now more GNU standards compliant (wrt |
|
command-line options). |
|
New command-line-option: --die-on-signal |
|
Errors are now directed to stderr. |
|
Stdout is now unbuffered, if it is a tty. |
|
User input device redirection (for filters) is now possible. |
|
|
|
Ports: |
|
|
|
Now runs on IRIX (and other MIPS-based systems without linker-flag -d). |
|
Direct threading now works on PowerPC (20% speedup on 604e). |
|
Better support for m68k (thanks to Andreas Schwab and Jorge Acereda). |
|
It is possible to create executables that contain the image (for |
|
non-OS systems). |
|
|
|
Added a lot of embedded control (EC) stuff. Supported controllers and |
|
small CPUs are Siemens C16x, 8086, 6502, Mixed-Mode's FPGA MISC, Bernd Paysan's |
|
4stack processor. Not finished: ShBoom alias PSC1000, H8, AVR. |
|
|
|
New, changed, and removed words: |
|
|
|
Renamed F0 to FP0 (avoids unexpected behaviour in hex), added aliases |
|
SP0, RP0, LP0 (recommended for future use) for S0, R0, L0. |
|
Renamed PARSE-WORD into SWORD (PARSE-WORD is used with the meaning of |
|
NAME in OpenBoot and dpans6 A.6.2.2008) |
|
Added FPICK (suggested by Julian Noble). |
|
Added EXCEPTION. |
|
S" gforth" ENVIRONMENT? now produces the version-string. |
|
Changed representation of types in struct package, and correspondingly |
|
changed names. |
|
|
|
Miscellaneous: |
|
|
|
Plain text documentation is now available in doc/gforth.txt. |
|
Documentation improvements. |
|
Wordlist structure changed. |
|
Added mini-oof. |
|
Reorganized files: added directories and reorganized many files into |
|
them; renamed files into 8.3 format to work with completely broken |
|
systems (but there are again some files that won't work there). |
|
Bug fixes. |
|
Various changes without log information only known as mega-patches. |
|
Cross compiler now also supports compilation only for undefined or forward |
|
referenced words. Plugins to support some native code generation |
|
(for PSC1000). |
|
More files in the compat library. |
|
|
|
|
|
|
|
User-visible changes between 0.2.1 and 0.3.0: |
|
|
|
Stack overflow detection by memory protection on most systems |
|
(allocation with mmap). |
|
gforth.fi is now fully relocatable. |
|
fully relocatable images are now easier to create. |
|
added primitives K and UNDER+. |
|
Win32 support. |
|
Improved support for embedded controllers and other deprived environments. |
|
some bug fixes. |
|
added concept index; other documentation improvements. |
|
