L1VM (2.8.5)
Added vm/modules/string: MSYS2 fixing false positive BOUNDSCHECK array overflow messages.

-- Stefan Pietzonke jay-t@gmx.net Son 14 Dec 2023 01:38 +0100

L1VM (2.8.4)
Added net module read/write byte arrays

-- Stefan Pietzonke jay-t@gmx.net Son 31 Dec 2023 15:18 +0100

L1VM (2.8.3)
Added l1vmgodata links between keys added.
See l1vmgodata on GitHub.

-- Stefan Pietzonke jay-t@gmx.net Sat 23 Dec 2023 18:49 +0100

L1VM (2.8.2)
l1pre preprocessor:
Added:

#docustart
#docuend

You can write documentation inside this two flags.
The preprocessor outputs this into "out.md" Markdown file.
See "prog/math-circle-bignum" for an example.

Added crypto module public/private keys generation and encryption/decryption.

BUGFIX: compiler line: main.c 1786 and following: variable to array assign code fixes.

Added crypto module key hashing and testing functions.
Added crypto module single key generation via password.

-- Stefan Pietzonke jay-t@gmx.net Mon 18 Dec 2023 18:33 +0100

L1VM (2.8.1)
VM: added "-fPIE" flag to RELRO zerobuild scripts.

-- Stefan Pietzonke jay-t@gmx.net Mon 27 Nov 2023 19:10 +0100

L1VM (2.8.0)
Now I did change the way how local and global variables are used.
I did add two new compiler flags:

(variable-local-on)
    (variable-local-off)

If the flag is set to one then only the current function local variables and the main function global variables can be accessed.
You need to use this in your main function:

#var ~ main

So all variables in main are set with the "main" ending:

(set int64 1 foo~ 12)

This variable would be named "foomain".
If you want to see an example then have a look at: "prog/math-circle-bignum-2.l1com".

UPDATE: string module: all MAXLINELEN now replaced by MAXSTRLEN!

NEW: I did add a experimental install script for NetBSD. It may not work at all.
I need to test it on my NetBSD installation.

-- Stefan Pietzonke jay-t@gmx.net Sat 18 Nov 2023 18:06 +0100

L1VM (2.7.3)

-- Stefan Pietzonke jay-t@gmx.net Sun 12 Nov 2023 17:40 +0100

L1VM (2.7.2)
I did set a maximum source code line length tp 512 chars.
The default settimng was 4096 and this was way to high for programs with a lot of lines.

Update: now the network module uses a read/write buffer on the file send function.
This gives a very high speedup!

-- Stefan Pietzonke jay-t@gmx.net Fri 10 Nov 2023 17:09 +0100

L1VM (2.7.1)
NEW: MPFR module: mp_set_float_prec function to set numbers base and precision (internal bits).
So you can calculate with real big numbers.
See prog/primes-bignum.l1com.

-- Stefan Pietzonke jay-t@gmx.net Mon 06 Nov 2023 19:51 +0100

L1VM (2.7.0)
I did change the way how the global data is used.
It is now possible to allocate local data in a thread.
The "data_local_alloc" interrupt allocates local memory and copies the whole global data in it.
So all data accesses in the thread are local. As long as you don't switch to global data.
See "prog/hello-thread-3-local.l1com" and "prog/webserver-thread-local.l1com".

-- Stefan Pietzonke jay-t@gmx.net Mon 23 Oct 2023 20:56 +0200

NEW: This version has the working Haiku installer scripts.
So Haiku OS is now official supported.

-- Stefan Pietzonke jay-t@gmx.net Fri 7 Jul 2023 17:09 +0200

L1VM (2.4.1)
BUHFIX: The compiler now checks if a variable was already defined at "set".
So this will result in an error!

BUGFIX: now the infix/RPN parser works again! Sorry for this!

Added "install-zerobuild-openbsd.sh" experimental install script for OpenBSD.
Added VM range check now prints out variable value and min max values.

Set STACKSIZE in include/global.h to 4096 bytes. Should be enough!

NEW: VM "get_size" interrupt 33 pointer variable to get the variable size in bytes.

Also gives an error if the variable inside a math expression is an array!

NEW: checks on variable to array and array to variable: make sure variable type is not array on assign:

(array tarray [ index ] =) -> error
(tarray [ index ] array =) -> error

Preprocessor now gives error message if #include is with quotes " ", instead of < >.
So if not an Brackets source code file is compiled, you get an error message!

Added checks if source code line has brackets or not. Give a compiler error if no brackets are found in line.
So the Brackets compiler now does not crash any mor on non Brackets source code files!

NEW: prog/bool.l1com include/bool.l1h : define variable true/false.

Now boolean variable assign is checked by the "bool" command:

(bool true Bool =)

Only "true" or "false" are allowed in this expression!
Here the variable "Bool" will be set to "true".

Compiler:
NEW: new "bool" variable type in "set" variable setting.
The bool variable name must begin with a uppercase "B"!

So you cant pop of a byte if there is a int64 on top!

NEW: macOS now has string bounds check in string module!
Now the other modules use bounds check on macOS too.
Stack check errors was coming from too old memobj library.
Now stack check is set to 1 in settings.h!

Build scripts on Linux and macOS now build missing modules.

L1VM - 1.4.3

L1VM - (1.4.3)
VM: main function now uses wait loop thread 1 on macOS only.
On macOS the main program will run in thread 0. This is needed to run the SDL module.
It can only be run from main program!
The other OS will run the VM bytecode in thread 1.

L1VM - (1.4.2)

JIT-compiler now sets a return code for run function and exits the program on error!

NEW: intr.l1h: global pthread mutexes lock/unlock: globallock/globalunlock.
It can be up to 255 mutexes set!
See example hello-thread-4.l1com.

Compiler: BUGFIX: now if espression with double numbers don't results in cast error.

Compiler: BUGFIX: updated if expression error message with double numbers.

L1VM - (1.4.1)
NEW: compiler now gives errors if array variable assign gives loose in precision.
For example assign int64 to an int32 array!

NEW: compiler now gives an error if array variable is to small at definition.
NEW: compiler now has: "-werror" flag to handle all warnings as errors!
This is used for variable type safety checking warnings!

NEW: type cast: 
(set int64 1 y 42)
(set int32 1 a 0)
(cast y a =)

Will cast from int64 to int32 without errors! As set by the programmer.
JIT-compiler now sets a return code for run function and exits the program on error!

See more on Changelog!!!

L1VM - 1.1.4

L1VM - (1.1.4)
NEW: I added the fp16 fixed floating point library as a module.
See prog/math-circle-nofp.l1com. The range goes from -32767 to 32767.
It is for CPUs without floating point opcodes.
I did this for use on Kludged Linux on my Psion 5MX.
As there is no floating point numbers support there!

UPDATE: I did update the sign and download scripts for L1VM packages on my repository.
BUGFIX: endianess library n_to_hostw function now set.

NEW: messages-lib: "include-lib/messages-lib.l1h" for sending and receiving messages codes.
See example "lib/messages-lib.l1com"

NEW: SDL module:
set_gadget_string_multiline, change_gadget_string_multiline and get_gadget_string_multiline.
See lib/sdl-lib-test.l1com for an example.
This is the multiline string edit gadget.

   NEW: the JIT-compiler is now added as open source.

L1VM - (1.1.3)
BUGFIXES: VM: math module serious stack type BUGFIXES!
prog/build-all.sh: wrong suffixes BUGFIX!
Now no filenames like foobar.l1com.l1db are there!

NEW: ranges interrupts: 28/29 to check if a variable is in a defined range.
See "include/intr.l1h"

NEW: "prog/shell.l1com": a simple L1VM shell. You can run L1VM programs by
the commands: "run" or simple by "!":

l1vm-sh $ run hello-2
l1vm-sh ! hello-2

All other commands are executed as normal.
NEW: there is a new shell: "shell-2.l1com" with a "<" command to list
the command history. You have to enter the number before the command to
execute it.

L1VM - (1.1.2)
NEW: I updated the distribution scripts to download and install programs from my own repo.
Now readme files can be installed via download script too, if there!
The installation path is ~/l1vm/man.

Added a Raspberry Pi build script. And did some changes to the other build scripts too!
So there is no ERROR exit if a module fails to build.

NEW: build script: "build.sh" now must be called without ".l1com" filename extension:

$ ./build.sh prog/hello

This will build the "hello.l1com" program.

NEW: Stack check setting in include/global.h: STACK_CHECK.
If set to 1 then you will get run time errors if something went wrong on stack.
Some programs do not work if it is switched on!
