 Latest features Now supports AVX512 by using the -cpuX86_64v4 flag. Additional APL style operations supported PREF and SUFF generate prefix and suffix vectors after style of Iversons alpha and omega operators. In fact the appropriate APL unicode are recognised by the compiler. The APL style rotate operator on arrays has been added, written either as ROT or as the corresponding APL symbol. The INDEX function has been introduced to do the same as the APL select construct. For example program select; const n=40;m=10; var nums:array[1..n] of integer; mask:array[1..n] of boolean; indices:pivector; begin	nums := random mod 1000 ;	mask := (nums mod m)<2;	indices:=index(mask[]);	writeln(indices^);	writeln(nums[indices^]); end. We initialise nums with numbers in 0..999, and form a mask of those numbers whose last digits are 0 or 1. We use index} to form the indices of where the mask array was true\footnote{The index funtion takes a dynamic array slice as its parameter, we form a slice comprising the whole array with the construct {\tt mask[]}.}. We then produce a table of the positions and numbers at these positions Installation details Unpack a recent version of either the install.jar file or the install.zip file. You can do this by using the jar -xf install.jar command, or by usings a windows unzip package. This will create a directory mmpc containing the files needed by the compiler. Dependencies ------------ Java, Nasm, Gcc, atyle, sablecc, M4 macro processor if you are doing source development work. Nvidia GPU requires nvcc in addition to above, and a GPU with compute capability 3.0 and above. You can install either from source or from the download files install.win32.zip or install.linux.tar.gz If installing from source, you should run the command make install to create the installation archives. On Linux -------- If you are just running the compiler to compile Pascal source you need : (Sun's) Java, Nasm, Gcc and Nvcc if compiling to an Nvidia GPU. GCC is used to build and link runtime libraries to the assembler produced by Vector Pascal. On Linux the standard GCC compiler will work. Extract the mmpc directory from install.tar.gz with the command: tar -zxvf install.linux.tar.gz You will now need to build a compatible RTL by doing the following: Go into the directory mmpc and type make rtl and then type make rtl.o Optionally, place the directory mmpc on your path with the following command: export PATH=$PATH:/path/to/mmpc Note that this will have to be set to run every time your computer starts. If you have altered the locations of the installed files from the default, you will need to define the symbol mmpcdir to point at the directory containing mmpc.jar by running the following command: export mmpcdir=/path/to/mmpc On Windows ---------- When working on Windows some incompatibilities exist between different releases of GCC and of assemblers. The NASM assembler under Windows will only work reliably with the djgpp release of GCC and not with Cygwin. Given Cygwin's easy installation, when working with Windows, the prefered method is to use the Cygwin compiler, not the DJGPP compiler. If using the cygwin compiler specify that you are using the gnu versions of the code generator as this is required to produce gnu compatible assembler code. Examples of using the gnu versions of the compiler would be to specify -cpugnuP4 or -cpugnuPentium To install, first obtain a copy of Cygwin from http://cygwin.com/setup.exe or http://www.cygwin.com/ When installing Cygwin, add the "make" package to the default programs to install. Once Cygwin is installed, extract the VPC archive using the following: unzip install.win32.zip You will now need to build a compatible RTL by doing the following: Go into the directory mmpc and type make rtl Then type make rtl.o The environment variable "mmpcdir" will have to be set. This can be done by right clicking on "My Computer" and selecting "Properties". Select the "Advanced" tab and clicking on the "Environment Variables" button. mmpcdir should then be set to the path to the files you extracted earlier. Additionally, you may choose to add the same directory to your path. To execute, you can use either Cygwin's shell or a standard Dos prompt. ================================================================= If you want to use the pretty printer facility built into the compiler, then you will need Latex. If you want to use the garbage collector go into the directory for the garbage collector mmpc/rtl/gc and follow the instructions to build the Boehm garbage collection library gc.a then go into mmpc and type make rtlb.o For the Intel MIC (Xeon Phi) The compiler works as a cross compiler on the host machine. The compiler flag you must use is -cpuMIC to generate code for it. You need to have the intel MPSS package installed and you need to set up a pair of symbolic links on your path to the mic assembler and and mic gcc compilers. The Pascal compiler expects a mic version of the gnu assembler to be on its path with the name mic-as and a mic version of the gcc compiler with the name mic-gcc. At present it supports multi-core operations and basic SIMD operations on single precision floats. Double precision maths is still scalar.
