MachineSink: Fix and tweak critical-edge breaking heuristic. Per original comment, the intention of this loop is to go ahead and break the critical edge (in order to sink this instruction) if there's reason to believe doing so might "unblock" the sinking of additional instructions that define registers used by this one. The idea is that if we have a few instructions to sink "together" breaking the edge might be worthwhile. This commit makes a few small changes to help better realize this goal: First, modify the loop to ignore registers defined by this instruction. We don't sink definitions of physical registers, and sinking an SSA definition isn't going to unblock an upstream instruction. Second, ignore uses of physical registers. Instructions that define physical registers are rejected for sinking, and so moving this one won't enable moving any defining instructions. As an added bonus, while virtual register use-def chains are generally small due to SSA goodness, iteration over the uses and definitions (used by hasOneNonDBGUse) for physical registers like EFLAGS can be rather expensive in practice. (This is the original reason for looking at this) Finally, to keep things simple continue to only consider this trick for registers that have a single use (via hasOneNonDBGUse), but to avoid spuriously breaking critical edges only do so if the definition resides in the same MBB and therefore this one directly blocks it from being sunk as well. If sinking them together is meant to be, let the iterative nature of this pass sink the definition into this block first. Update tests to accomodate this change, add new testcase where sinking avoids pipeline stalls. llvm-svn: 192608

DebugInfo: Remove some unneeded conditionals now that DIBuilder no longer emits zero-length arrays as {i32 0} A bunch of test cases needed to be cleaned up for this, many my fault - when implementid imported modules I updated test cases by simply duplicating the prior metadata field - which wasn't always the empty metadata entry. llvm-svn: 200731

Split out filename & directory from DIFile to start generalizing over DIScopes This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. llvm-svn: 177239

Refactor the DIFile (2nd) parameter to DITypes to be an MDNode reference to a raw directory/file pair This makes DIType's first non-tag parameter the same as DIFile's, allowing them to both share the common implementation of getFilename/getDirectory in DIScope. llvm-svn: 177467
