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. |
