It should not get the reputation of being exceptionally slow. Bug fixes installation on big-endian machines sometimes did not work. It should become standard, i. At run-time requires libtool and gcc for the libcc C interface and gdb for the disassembler SEE on some platforms.

Plugins to support some native code generation for PSC Read old postings in the list archive of the Gforth list. Added optional support for a C interface built on the ffcall libraries more portable and powerful than the old one, but still not documented.

Added a lot of embedded control EC stuff. Changed representation of types in struct package, and correspondingly changed names. Contributions of assemblers and disassemblers for other architectures are welcome. Gforth now produces a backtrace when catching an exception.

Gforth now does not translate newlines to LFs on reading. It should provide for all the things that are considered necessary today and even some that are not yet considered necessary. Cross compiler now also supports compilation only for undefined or forward referenced words.

Gforth-fast now uses static superinstructions some speedup on some platforms ; generally this is transparent apart from the speedupbut there are lots of command-line options for controlling the static superinstruction generation. This can be split into several subgoals: Bug fixes gdorth gdb disassembler works with syntax change autodetected workaround for gcc 4.


Bug fixes Backported protection against glibc math functions clobbering TOS. 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.

Block files now start at block 0 by default instead of block 1.

More files in the compat library. It is possible to create executables that contain the image for non-OS systems.

Better support for m68k thanks to Andreas Schwab and Jorge Acereda. Long word names MB on bit systems are now supported change to the header format. News User-visible changes between 0.
