[llvm-commits] [PATCH 3/10] PowerPC64 local call small optimization

[Adhemerval Zanella]

This patch is a small optimization for local function call (within the
same module) for PPC64. This avoid the emission of the 'nop' meant to
restore the TOC across function calls in different modules, since function
in same module share the same TOC.

I also added testcase for PPC64 function call to check the nop creation
for external function call, indirect calls, absolute calls and local calls.
This is more complete than the current PPC64 call check
(test/CodeGen/PowerPC/ppc64-ind-call.ll).
