GNU Toolchain 4.1.1 and GDB for the Cell BE's PPU/SPU

stroke

The Cell BE's PPU (Power Processor Unit) uses the same instruction set as the PowerPC 970 processor. The toolchain includes a GCC compiler for PPU to cross-compile on x86 and as a replacement for the native GCC compiler on ppc platforms. The GCC compiler for the PPU is preferred and the make files are configured to use it when building the Libraries and Samples. This release also includes a Fortran compiler for PPU as a replacement for the native Fortran compiler on ppc platforms. The GCC compiler also contains a separate SPE cross-compiler that supports the standards defined in the SPU C/C++ Language Extensions V2.4, SPU Application Binary Interface Specification V1.7, and Synergistic Processor Unit (SPU) Instruction Set Architecture V1.11 documents. The associated assembler and linker additionally support the SPU Assembly Language Specification V1.5. The toolchain is based on a port of GCC, GDB and the GNU binutils to the Cell Broadband Engine Architecture (CBEA) provided by Sony Computer Entertainment Inc.

What's new

  • GNU GCC support for an enhanced CBEA compliant processor with a fully pipelined, double precision SPE.
  • Upgraded binutils version to 2.17.50 release.
  • Upgraded GDB version to 6.6.
  • Upgraded newlib version to 1.15.0.

The cross-compiling GNU Toolchain is installed into the /opt/cell/ directory while the ppc toolchain will be installed into /usr.

To install the GNU Toochain in a x86 box in order to cross-compile applications, you need to install the two following rpms:

File Description
ppu-sysroot-fc6-1.noarch.rpm Basic libraries and headers for cross-compiling to Cell Broadband Engine's PPU.
ppu-sysroot64-fc6-1.noarch.rpm Basic libraries and headers for cross-compiling to Cell Broadband Engine's PPU (64-bit).


GNU Toolchain Source distribution and build files

To rebuild the GNU toolchain, We provide the source rpms that can be easily installed but also the source tarballs and the set of patches that were used to build the binary distribution.


Source RPM packages

File Description
ppu-gcc-4.1.1-10.src.rpm GNU GCC source package for the Cell BE's PPU.
spu-gcc-4.1.1-9.src.rpm GNU GCC source package for the Cell BE's SPU.
ppu-binutils-2.17.50-8.src.rpm GNU Binutils source package for the Cell BE's PPU.
spu-binutils-2.17.50-8.src.rpm GNU Binutils source package for the Cell BE's SPU.
ppu-gdb-6.6-15.src.rpm GNU GDB source package for the Cell BE's PPU.
spu-gdb-6.6-12.src.rpm GNU GDB source package for the Cell BE's SPU.
ppu-sysroot-fc6-1.src.rpm PPU sysroot toolchain source package.
spu-newlib-1.15.0-7.src.rpm GNU newlib source package for the Cell BE's SPU.


Source tarball, patches and spec files


File Description
toolchain-3.4-src.tar.bz2 GNU Toolchain base source tarball for both PPU and SPU toolchain.
gdb-6.6.tar.bz2 GNU GDB base source tarball.
gcc-fortran-4.1.1.tar.bz2 GNU Fortran base source tarball for PPU toolchain.
newlib-1.15.0.tar.gz GNU newlib base source tarball.
binutils-2.17.50-20070112.tar.bz2 GNU Binutils source tarball for both PPU and SPU toolchain.

PPU Sysroot


File Description
ppu-sysroot.spec PPU Toolchain SPEC file.

To rebuild the PPU sysroot rpms you can install the source rpm and run the rpm_build.sh script: 

                  rpm -ivh ppu-sysroot-fc6-1.src.rpm
                  rpm_build.sh --none --pputoolchain

or if you prefer to do it manually you have to:

  1. Download and copy to /usr/redhat/SOURCES the following FC6 rpms:


  2. Copy the ppu-sysroot.spec file to /usr/redhat/SPECS
  3. Move to /usr/redhat/SPECS directory and type: 
         rpmbuild -ba ppu-sysroot.spec --target noarch
