User-visible changes between 0.6.2 and 0.6.9 (up to 2008-07-15): |
| |
|
| |
Requirements: |
| |
At run-time requires libtool and gcc (for libcc C interface) and |
| |
gdb (for disassembler (SEE) on some platforms). |
| |
Installation: |
| |
support for DESTDIR, POST_INSTALL, INSTALL_SCRIPT |
| |
automatic performance tuning on building (--enable-force-reg unnecessary) |
| |
report performance and functionality problems at end of "make" |
| |
autogen.sh now exists |
| |
License: |
| |
Changed to GPLv3 |
| |
Bug fixes |
| |
Now works with address-space randomization. |
| |
The single-step debugger works again in some engines. |
| |
Many others. |
| |
Ports: |
| |
AMD64, ARM, IA-64 (Itanium): better performance |
| |
PPC: disassembler and assembler (32-bit) |
| |
Gforth EC: R8C, Lego NXT (not distributed; complete?) |
| |
MacOS X: better support |
| |
Invocation: |
| |
New flags --ignore-async-signals, --vm-commit (default overcommit) |
| |
--print-sequences |
| |
Forth 200x: |
| |
extension queries (produce true for all implemented extensions) |
| |
REQUIRED etc. (not new) |
| |
[DEFINED] and [UNDEFINED] |
| |
PARSE-NAME (new name) |
| |
deferred words (new: DEFER@ DEFER! ACTION-OF) |
| |
X:structures: +FIELD FIELD: FFIELD: CFIELD: etc. |
| |
X:ekeys: new: EKEY>FKEY K-SHIFT-MASK K-CTRL-MASK K-ALT-MASK K-F1...K-F12 |
| |
Unicode support (currently supports only uniform encoding): |
| |
added xchars words for dealing with variable-width multi-byte characters |
| |
provide 8bit (ISO Latin 1) and UTF-8 support for xchars |
| |
Number prefixes: |
| |
0x is a hex prefix: 0xff and 0XfF now produces (decimal) 255 |
| |
# is a decimal prefix: #10 now produces (decimal) 10 |
| |
Signs after the number prefix are now accepted, e.g, #-50. |
| |
' now only handles a single (x)char: 'ab is no longer accepted, |
| |
'a' now produces (decimal) 97 |
| |
New words: |
| |
\C C-FUNCTION C-LIBRARY END-C-LIBRARY C-LIBRARY-NAME (libcc C interface) |
| |
LIB-ERROR (complements OPEN-LIB) |
| |
OUTFILE-EXECUTE INFILE-EXECUTE BASE-EXECUTE (limited change of global state) |
| |
16-bit and 32-bit memory acces: UW@ UL@ SW@ SL@ W! L! W@ L@ /W /L |
| |
NEXT-ARG SHIFT-ARGS (OS command-line argument processing) |
| |
NOTHROW (for backtrace control) |
| |
FTRUNC FMOD (undocumented) |
| |
SEE-CODE SEE-CODE-RANGE (show generated dynamic native code) |
| |
Improvements/changes of existing words: |
| |
S\", .\" now support \l, \m, \z, and limits hex and octal character specs. |
| |
OPEN-FILE with W/O no longer creates or truncates files (no compat. file) |
| |
OPEN-LIB now understands ~ at the start, like OPEN-FILE. |
| |
TRY...ENDTRY changed significantly, compatibility files available (see docs). |
| |
The disassembler (DISCODE) can now use gdb to disassemble code |
| |
Uninitialized defered words now give a warning when executed |
| |
Division is floored (disable with "configure --enable-force-cdiv") |
| |
Gforth (not gforth-fast) reports division by zero and overflow on division |
| |
on all platforms. |
| |
Newly documented words: |
| |
S>NUMBER? S>UNUMBER? |
| |
EKEY keypress names: K-LEFT K-RIGHT K-UP K-DOWN K-HOME K-END K-PRIOR |
| |
K-NEXT K-INSERT K-DELETE |
| |
CLEARSTACKS |
| |
FORM |
| |
Environment variable GFORTHSYSTEMPREFIX (used by word SYSTEM and friends) |
| |
C interface: |
| |
exported symbols now start with "gforth_" (for referencing them from C code) |
| |
libcc C function call interface (requires libtool and gcc at run-time) |
| |
alternative: undocumented libffi-based interface |
| |
Libraries: |
| |
depth-changes.fs: report stack depth changes during interpretation |
| |
ans-report.fs now reports CfV extensions |
| |
fsl-util.4th: FSL support files (undocumented) |
| |
regexp.fs for regular expressions (undocumented) |
| |
complex.fs for complex numbers (undocumented) |
| |
fft.fs for Fast Fourier Transform (undocumented) |
| |
wf.fs, a Wiki implementation (undocumented) |
| |
httpd.fs, a web server (undocumented) |
| |
status.fs, show interpreter status in separate xterm (undocumented) |
| |
profile.fs for profiling (undocumented, incomplete) |
| |
endtry-iferror.fs, recover-endtry.fs to ease the TRY change transition |
| |
test/tester.fs: Now works with FP numbers (undocumented) |
| |
test/ttester.fs: Version of tester.fs with improved interface (T{...}T). |
| |
compat library: |
| |
compat/execute-parsing.fs |
| |
Speed improvements: |
| |
automatic performance tuning on building |
| |
static stack caching (good speedup on PPC) |
| |
mixed-precision division is now faster |
| |
support for int128 types on AMD64 |
| |
workarounds for gcc performance bugs (in particular, PR 15242) |
| |
branch target alignment (good speedup on Alpha). |
| |
|

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. |
