Detailed Description
IBM Power Systems will be working in Fedora 18 to test, stabilize, and complete any missing features for LLVM for 32-bit and 64-bit applications. Work will include both statically compiled applications (with clang) and dynamic or JIT'd applications as used by LLVMpipe.
This work is ultimately about parity of Power Systems platform. No new feature/function is anticipated.
Benefit to Fedora
Consistency between hardware platforms in order to have the same user experience on IBM Power Systems as on Intel platforms. Primary use is to be able to support LLVMpipe to enable 3D graphics on IBM Power Systems, see feature page
https://fedoraproject.org/wiki/Features/VNCServerWithLLVMpipe
Scope
No new features/functions. Simple platform parity for IBM Power Systems to fully support LLVM in order to support LLVMpipe for 3D graphics over VNC.
How To Test
Existing tests should execute to parity with x86 platforms. Major consumers/users of LLVM in Fedora are:
CLang LLVMpipe
So recompilation and use of those on IBM Power Systems running Fedora 18 should work without problems.
User Experience
Primary focus is functional parity.
Dependencies
None.
Contingency Plan
None necessary, revert to previous release behavior.
Documentation
Existing LLVM documentation should be updated, if necessary, to indicate it works for ppc64 as it does for x86. This will be handled upstream.
