SaC standard library

build status contributions welcome

This repository consists of SaC modules with basic functionality like arithmetic, stdio, etc; which together form the standard library of the SaC language.

Build instructions

To build the system one requires an operational CMake >= 3.20, Flex, and Bison.

The quick and dirty option is just

make

You can also use the cmake build system for more control

mkdir build
cd build
cmake <OPTIONS> ..
make -j4

NOTE: When pulling the latest commit, remember to run git submodule update or you will be missing changes to the cmake-common repository.

Variables that can be passed to CMake

When running CMake it is possible to pass the following variables:

  • -DTARGETS=x;y;z --- build stdlib for targets x, y and z. (Defaults to seq;mt_pth)
  • -DBUILDGENERIC=ON|OFF --- build stdlib without using architecture specific optimisations (useful when creating distributable packages). (Default is OFF)
  • -DSAC2C_EXEC=/path/to/sac2c --- specify sac2c executable directly. Otherwise CMake will try to find sac2c on yout PATH.
  • -DLINKSETSIZE=n --- set -linksetsize n when calling sac2c. This option is responsible for the number of C functions that are put in a single C file when compiling a SaC program. The rule of thumb:

    • value 0 is the fastest time-wise but potentially results in a large memory consumption

    • value 1 reduces the memory consumption to minimum, but significantly increases compilation time.

      Default value: 500.

  • -DFULLTYPES=ON|OFF --- add support for further types to the stdlib, such as long and longlong (Default is ON).
  • -DBUILD_EXT=ON|OFF --- build extended stdlib (see cmake/source-core-ext.txt for details) (Default is ON)

Continuous Integration

We make use of Github Actions for our CI pipeline, building the standard library on different systems anytime there is a pull request. Build will fail if there are any compile-time warnings.

Please look at .github/workflows/ for more exact details on what we do.
