[llvm-dev] Configuring LLVM Sparc target for Leon 3 and Leon 4 variants

[Martin J. O'Riordan via llvm-dev]

Thanks very much Doug, that is really useful information.  If it’s that close I should be able to wade in and help out in completing it.

 ·         It is not 100% clear to me that the existing backend fully supports the Sparc V8 architecture, and the Leon variants in particular.  Does anyone know whether this architecture is supported in the Sparc backend?

Full support for v8,v8+ looks like it's getting close.  Nothing Leon-specific, but a few folks seem to be adding missing instructions occasionally. 

·         How easy is it to configure the existing Sparc back-end for bi-endian code generation?

It can already do that.
