* Turn on the new instprinter by default.Chris Lattner2010-11-151-1/+1
| | | | | | | | | | | | | | | | The only change in the output is: 1) we get a better comment on mfcr, we get: mfcr r2 ; cr2 instead of: mfcr r2 ; 32 2) we no longer emit $stub's on powerpc/leopard. The Leopard linker autosynthesizes them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119108 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | nodes to indicate when ha16/lo16 modifiers should be used. This lets us pass PowerPC/indirectbr.ll. The one annoying thing about this patch is that the MCSymbolExpr isn't expressive enough to represent ha16(label1-label2) which we need on PowerPC. I have a terrible hack in the meantime, but this will have to be revisited at some point. Last major conversion item left is global variable references. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119105 91177308-0d34-0410-b5e6-96231b3b80d8

Note that this code could be replaced by a call to PN->hasConstantValue(). However since we bail out the moment we see a non-constant operand, it is more efficient to have a specialized version of that logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119041 91177308-0d34-0410-b5e6-96231b3b80d8
