Debug info for optimized code: Support variables that are on the stack and
described by DBG_VALUEs during their lifetime. Previously, when a variable was at a FrameIndex for any part of its lifetime, this would shadow all other DBG_VALUEs and only a single fbreg location would be emitted, which in fact is only valid for a small range and not the entire lexical scope of the variable. The included dbg-value-const-byref testcase demonstrates this. This patch fixes this by Local - emitting dbg.value intrinsics for allocas that are passed by reference - dropping all dbg.declares (they are now fully lowered to dbg.values) SelectionDAG - renamed constructors for SDDbgValue for better readability. - fix UserValue::match() to handle indirect values correctly - not inserting an MMI table entries for dbg.values that describe allocas. - lowering dbg.values that describe allocas into *indirect* DBG_VALUEs. CodeGenPrepare - leaving dbg.values for an alloca were they are (see comment) Other - regenerated/updated instcombine-intrinsics testcase and included source rdar://problem/16679879 http://reviews.llvm.org/D3374 llvm-svn: 207130
