L1VM (3.0.0)
NEW: now math expressions can be written like this in Brackets:
{i = xd + yd}
The () brackets are not longer needed for this, to work.
The old way was:
{i = (xd + yd)}
-- Stefan Pietzonke <jay-t@gmx.net> Thur 1 Feb 2024 21:18 +0100
L1VM (2.9.0)
Added "return" to compiler. See "prog/return.l1com".

Added disassembler: in disasm directory.
-- Stefan Pietzonke <jay-t@gmx.net> Wed 24 Jan 2024 19:31 +0100
L1VM (2.8.6)
The preprocessor now removes empty .md documentation files.
The "l1vm-build.sh" script checks now if a "out.md" file exists and copies it if so.
-- Stefan Pietzonke <jay-t@gmx.net> Thu 18 Jan 2024 18:55 +0100
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

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.

-- 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)
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> 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

Net module socket_write_string: possible buffer overflow fix!
-- Stefan Pietzonke <jay-t@gmx.net> Sun 01 Oct 2023 20:35 +0200

New: compiler flags:
(variable-immutable) (variable-mutable) to set the default behavior on variables.
See demo prog/hello-mut.l1com!
Update: syntax highlighters to contain new "mut-byte" etc. variable definitions.
NEW: most installation scripts now install the binaries and libraries into ~/l1vm/bin
You have to set this directory in your PATH and LD_LIBRARY_PATH env variables!
-- Stefan Pietzonke <jay-t@gmx.net> Sun 01 Oct 2023 10:31 +0200
L1VM (2.6.1)

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!

L1VM - (1.1.1)
Updated the osv examples.
BUGFIXES: compiler and assembler now do ERROR exit if the line length in programs
is too long!
NEW: VM: string input now uses memory bounds check to find string length overflow!
NEW: added missing Raspberry Pi GPIO wrapper functions for all functions.
Removed asmjit library from linking to VM binary. It will be linked to JIT-compiler module.
NEW: VM mem module now sets the size for a vector array dynamically.
BUGFIX: Added VM math module: double_rounded_string function return string length check.
NEW: added distribution folder: there is a script to sign .l1obj files and one to download them from a server and run them.
NEW: modified build.sh script, now flags can be set:
$ ./build.sh prog/hello.l1com -pack -lines 100000
Builds a packed .l1obj.bz2 file and sets the max linenumber to 100000.
NEW: the webserver program now searches for files in the ~/l1vm/web directory.

L1VM - (1.1.0)
NEW: math module: more functions added from C math library
NEW: mpfr math library:
I included a patched version of "mpreal.h"
I did replace all places with "srcptr()"" to "xsrcptr()".
This makes it possible to use "mpreal.h" with recent versions of mpfr library, which
defined "xsrcptr" to something else!
NEW: "clang-toolchain" directory added with "build-toolchain-12.0.sh" script to
build Clang 12.0.0 C compilers.
NEW: VM: interrupt 0: 27 print out DEBUG marking text and current epos.
BUGFIXES: VM: set missing "eoffs = 5" on interrupts.
BUGFIXES: VM: string module bugfixes "string_mid" function.
NEW: VM math module now uses libcrypt (openssl) function for generating random number seeds.
NEW: "intr.l1h" now has "debug" interrupt "intr0" 27 to show current execution position.

L1VM - (1.0.15)
NEW: sdl sdl_toggle_mouse_pointer:
// hide mouse pointer
(zero :sdl_toggle_mouse_pointer call)
// show mouse pointer
(one :sdl_toggle_mouse_pointer call)
Compiler: removed not needed protos. Added main.h header file.
Assembler: cleanup and added main.h header file.
VM: cleanup and added main.h header file.
SDL module: "set_gadget_string_passwd" function to hide input by showing just stars!
See "lib/sdl-lib.l1com" example for more!
NEW: experimental VM module math-lib-vect for array vector math.
This makes it possible for example add a number to all array indexes.
Or add two arrays and store the results in a third array.
See the "lib/math-lib-vect.l1com" example!
NEW: compiler now sets "loadreg" automatically if not set after stpop opcodes!
NEW: compiler RPN math code bugfixes.
Infix math to RPN conversion code seems to work now!
-- Stefan Pietzonke <jay-t@gmx.net> Sat Jun 5 2021 06:17 +0200
L1VM - (1.0.14)
Infix math expression to RPN converter now prints error message if brackets "()" don't match.
NEW: compiler - array variable assign in multi lines:
See prog/array-test.l1com
(set int64 5 arr_0 10 5 /)
@, 1234567890, 4, 3, ;
NEW: prog/start.l1com, prog/sdl-4.l1com, prog/sdl-5.l1com
and prog/webserver.l1com now use includes for the libraries!
NEW: prog/hello-for-2.l1com and prog/hello-while-2.l1com examples added.
NEW: BUGFIXES in the compiler by Andreas Weber (Andy1978).
And more help from him: the "run_ccpcheck.sh" script to find coding BUGS.
Thank you!
NEW: zerobuild and make scripts now use "-Wall -Wextra" compile flags!
And I added "vm/zerobuild-debug.txt" make script to use libasan fsanitize debug library.
NEW: sdl open screen:
(zero width height bit fullscreen :sdl_open_screen call)
If fullscreen is set to "1" then full screen mode is set!

L1VM - (1.0.13)
NEW: added network library "socket_get_file" function, to download a file via TCP/IP. (WIP)
net-lib-get-file.l1com
BUGFIX: network library: "socket_send_file", filename get first char fix!
NEW: math expressions in { }, are parsed as reverse polish notation:
{a = x y + z x * *}
is the same as: "a = x + y * z * x"
This needs no brackets for complex math expressions!
See "prog/hello-4.l1com" example!
NEW: function to convert infix to RPN if brackets are found in expression:
{ret = (y + z) * ((z + y) * foo)}
converts to RPN:
{ret = y z + z y + foo * *}
global.h: pragma messages for ALIGNMENT and MATH are moved to vm/main.c.
