Welcome to the ispc wiki! This wiki collects information related to the design and implementation of the ispc compiler for anyone working on the source code. For now, documentation about using the ispc compiler is collected in the user's guide (http://ispc.github.com/ispc.html); it's an open question whether that should be transitioned to a wiki format as well.

Building the Compiler

These pages give an overview of the general process of building ispc from source.

• Building ispc from source on Windows
• Building ispc from source on Linux and Mac OS X

ispc uses the LLVM libraries--here is a page that tracks bugs in LLVM that impact ispc.

Testing the Compiler

The compiler tests should always be run before any check in.

• Running the ispc regression tests

Design Notes / Plans

Here are some collected notes and possible ideas related to future changes and additions to the compiler. (Fully baked things that are definitely worth doing and have a clear implementation path are captured in the issues tracker (https://github.com/ispc/ispc/issues), while the things here are still in the process of being defined.

• New gather/scatter infrastructure
• Better in-language support for AoSoA layout
• Additional IR step between AST and LLVM IR
• Various other rough language features
