The official OpenEmbedded/Yocto BSP layer for the VectorFabrics Pareon compiler.
The meta-pareon layer depends on:
URI: git://git.openembedded.org/openembedded-core
layers: meta
branch: dizzy
Please follow the recommended setup procedures of your OE distribution. For Angstrom that is http://www.angstrom-distribution.org/building-angstrom, other distros should have similar online resources.
Add this layer to your layerstack the way you usually do, this differs between projects using OpenEmbedded. The steps should include updating conf/bblayers.conf. Please refer to the documenation of your project for the exact steps.
To (re)build recipes with the Pareon compiler, add the following to your conf/local.conf:
TOOLCHAIN_pn-<recipe> = "pareon-verify"
Alternatively, run the generator script. The script accepts multiple recipe names:
user@ubuntu-vm:/OE/sources/meta-pareon$ ./scripts/generate-conf.sh helloworld bash
TOOLCHAIN_pn-helloworld = "pareon-verify"
TOOLCHAIN_pn-bash = "pareon-verify"
Copy/paste the output into conf/local.conf.
- pareon-verify
- pareon-profile
- pareon-verify-with-fallback
- pareon-profile-with-fallback
The last two toolchains fallback to GCC for any specific file that fails to compile with vfcc.
Several packages are known to refuse instrumentation. They are listed in the file BLACKLIST.md.
Use the pareon_run.sh wrapper script to setup the necessary environment variables when analyzing programs on the target.
pareon_run.sh program_name arguments
For Pareon Profile, use pareon_profile_run.sh:
pareon_profile_run.sh program_name arguments
You may also specify the Pareon version through the PAREON_VERSION variable, like so:
PAREON_VERSION = "2.26"
This will use the compiler and libraries from the /opt/vectorfabrics/pareon-2.26/ folder.
By default meta-pareon will use the latest Pareon installed.
