LLVM support on 64-bit POWER systems


Power Systems needs to ensure that LLVM supports the platform.


  • Email: scheel@us.ibm.com

Current status

  • Targeted release: Fedora 18
  • Last updated: 2012-07-24
  • Percentage of completion: 0%

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.


No new features/functions. Simple platform parity for IBM Power Systems.

How To Test

Existing tests should execute to parity with x86 platforms.

User Experience

Primary focus is functional parity.



Contingency Plan

None necessary, revert to previous release behavior.


Existing LLVM documentation should be updated, if necessary, to indicate it works for ppc64 as it does for x86.
