|
| Added form, rows, and cols. |
Requirements: |

| |

| |
support for int128 types on AMD64 |
| |
workarounds for gcc performance bugs (in particular, PR 15242) |

| |
|
| |
|
| |
User-visible changes between 0.6.1 and 0.6.2: |
| |
|
| |
Bug fixes (in particular, gforth-0.6.2 compiles with gcc-3.3) |
| |
New words: LATEST, LATESTXT (LASTXT deprecated) |
| |
Operating environment: Added optional support for a C interface built |
| |
on the ffcall libraries (more portable and powerful than the old |
| |
one, but still not documented). To use it, the ffcall libraries |
| |
have to be installed before building Gforth (see INSTALL). |
| |
Miscellaneous: Gforth-fast now uses static superinstructions (some |
| |
speedup on some platforms); generally this is transparent (apart |
| |
from the speedup), but there are lots of command-line options for |
| |
controlling the static superinstruction generation. |
| |
|
| |
|
| |
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: |
| |
|
| |

| |
(allocation with mmap). |
| |
gforth.fi is now fully relocatable. |
| |
fully relocatable images are now easier to create. |
| |
added primitives K and UNDER+. |
| |
