Nick Briggs 98569d10b4 Reduce false positives for misaligned pointer access when checking array blocks
The forward and backward pointers in an array block only contain
    valid pointer values when the block is free therefore avoid
    producing native addresses from these fields if the block is in use.

Add comments regarding the operation of the array block merging code
    Array block merging will produce a single block if possible,
    otherwise it will produce two blocks with one as large as possible
    and the other no less than the minimum block size.

Rewrite the checks in array block merge forward to minimize unnecessary field accesses

Maiko

Maiko is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display (via X11) and disk etc.

For an overview, see Medley Interlisp Introduction.

See the Medley repository for

Bug reports, feature requests, fixes and improvements, support for additional platforms and hardware are all welcome.

Development Platforms

We are developing on FreeBSD, Linux, macOS, and Solaris currently on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.

Building Maiko

Building requires clang, make, X11 client libraries (libx11-dev). For example,

$ sudo apt update
$ sudo apt install clang make libx11-dev
$ cd maiko/bin
$ ./makeright x
  • The build will (attempt to) detect the OS-type and cpu-type. It will build binaries lde and ldex in ../ostype.cputype (with .o files in ..ostype.cputype-x. For example, Linux on a 64-bit x86 will use linux.x86_64, while macOS 11 on a (new M1) Mac will use darwin.aarch64.
  • If you prefer using gcc over clang, you will need to edit the makefile fragment for your configuration (makefile-ostype.cputype-x) and comment out the line (with a #) that defines CC for clang and uncomment the line (delete the #) for the line that defines CC for gcc.
  • There is a cmake configuration (TBD To Be Described here).

Building For macOS

  • Running on macOS requires an X server, and building on a Mac requires X client libraries. An X-server for macOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases

Building for Windows 10

Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server). See Medley's README for more.
