Source Code

Most of the Tilera toolchain and runtime software has been returned to the community; this web site hosts sources that have not yet been returned, as well as some backports to earlier versions.

• The binutils distribution has included support for both tilepro and tilegx since release 2.22. However, a couple of minor extensions are present in the latest binutils snapshot (for example, here), which are assumed by newer versions of the compiler.
• gcc has been returned to the community and will be in the 4.7.x series; until the official release, you can download a gcc 4.7 snapshot. We host patch backports for 4.4.6 and 4.6.2 as well (about 2.8MB each).
• Linux kernel sources have been available as part of the standard distribution from kernel.org since Linux 2.6.36 (tilepro) or Linux 3.0 (tilegx). Sometimes branches with material that has not yet made it to mainline can be found in the linux-tile tree on kernel.org.
• glibc has been returned to the community, and we anticipate it will be in the 2.15.1 release. Meanwhile you can apply a patch (300 KB) to the standard Red Hat Enterprise Linux 6.2 version of glibc (based on glibc 2.12).
• gdb-7.1 community return is ongoing; meanwhile we provide a patch (1 MB) for tile for gdb 7.1.

Prebuilt RedHat RHEL5 x86_64 cross-compilation tools are available in the tilepro-x86_64.tar.bz2 and tilegx-x86_64.tar.bz2 tarballs, each about 75 MB, which unpack to an "install" tree that can be located anywhere. Each tarball contains the basic cross-build environment built for x86_64 (binutils snapshot as of 3/12/2012, gcc 4.4.6 backport, glibc 2.12 backport, and gdb 7.1 backport). We build with "--sysroot" so that the "install" directory can be moved around or renamed after it is created.

If you want to build for a different host, or rebuild after modifying the tool chain sources, you will need to follow the tool-chain build process described in the Building from Source documentation.
