New Revision: 252865
URL: http://llvm.org/viewvc/llvm-project?rev=252865&view=rev
Log:
Add AVR backend skeleton
This adds part of the target info code, and adds modifications to
the build scripts so that AVR is recognized a supported, experimental
backend.
It does not include any AVR-specific code, just the bare sources required
for a backend to exist.
