2013-03-08Disable statistics on Release builds and move tests that depend on -stats.Jan Wen Voung
Summary: Statistics are still available in Release+Asserts (any +Asserts builds), and stats can also be turned on with LLVM_ENABLE_STATS. Move some of the FastISel stats that were moved under DEBUG() back out of DEBUG(), since stats are disabled across the board now. Many tests depend on grepping "-stats" output. Move those into a orig_dir/Stats/. so that they can be marked as unsupported when building without statistics.

2013-03-08R600/SI: Use source schedulerMichel Danzer
This is certainly not the last word on scheduling for this target, but right now this allows a few apps to run / finish with radeonsi, most notably UT2004 / Lightsmark. They fail to compile some shaders with the default scheduler because it ends up trying to spill registers, which we don't support yet (and which is probably a bad idea in general for performance if it can be avoided). NOTE: This is a candidate for the Mesa stable branch.

2013-03-08Revert r176154 in favor of a better approach.Bill Wendling
Code generation makes some basic assumptions about the IR it's been given. In particular, if there is only one 'invoke' in the function, then that invoke won't be going away. However, with the advent of the `llvm.donothing' intrinsic, those invokes may go away. If all of them go away, the landing pad no longer has any users. This confuses the back-end, which asserts. This happens with SjLj exceptions, because that's the model that modifies the IR based on there being invokes, etc. in the function. Remove any invokes of `llvm.donothing' during SjLj EH preparation. This will give us a CFG that the back-end won't be confused about. If all of the invokes in a function are removed, then the SjLj EH prepare pass won't insert the bogus code the relies upon the invokes being there. <rdar://problem/13228754&13316637> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176677 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-07Rename isEarlierInSameTrace to isUsefulDominator.Jakob Stoklund Olesen
In very rare cases caused by irreducible control flow, the dominating block can have the same trace head without actually being part of the trace. As long as such a dominator still has valid instruction depths, it is OK to use it for computing instruction depths. Rename the function to avoid lying, and add a check that instruction depths are computed for the dominator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176668 91177308-0d34-0410-b5e6-96231b3b80d8
