GCC packages for reliable MaverickCrunch code generation

Martin Guy <martinwguy@yahoo.it>
8 September 2009

Here are packages of the GCC C compiler modified to produce reliable code for the MaverickCrunch floating point unit.

They run on, and generate code for, the armv4t EABI architecture as used in the Debian "armel", Gentoo embedded and Ångström GNU/Linux distributions among others.

To generate the fastest code, I use: 

    gcc-4.3-crunch -mcpu=ep9312 -mfpu=maverick -mfloat-abi=softfp -ffast-math -O

Status

The 20090908 version has no known bugs for C. It doesn't restore floating point variables held in registers across a setjmp/longjmp call but that's a glibc issue.

Installation

On Debian "armel" systems, download the .deb file and say, as root, dpkg -i *.deb
The Debian package names are gcc-4.2-crunch and gcc-4.3-crunch in case you should wish to remove them later with dpkg -r

On other ARM Linux EABI systems, download the .tgz file and unpack it in the root directory with tar xzf *.tgz -C /

They install under /usr/local/{bin,lib,libexec} and do not affect the main system compilers.

For further details about them, as well as instructions for how to build the compiler from source, see martinwguy.co.uk/martin/crunch.

Download

Here are installable tarballs and Debian packages for the compiler and the corresponding patches to the GCC source code.
