| | | | | | | The config.h file's macros collide with other projects that include LLVM and shouldn't get exported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145215 91177308-0d34-0410-b5e6-96231b3b80d8
* rename ENABLE_THREADS to LLVM_ENABLE_THREADSDylan Noblesmith2011-11-28
| | | | | | | | | | | Now that it needs to be exported in a public header (Valgrind.h) it should be prefixed to avoid collision with other projects. Add it to llvm-config.h as well.

* Break false dependencies before partial register updates.Jakob Stoklund Olesen2011-11-15
| | | | | | | | | | | | | | Two new TargetInstrInfo hooks lets the target tell ExecutionDepsFix about instructions with partial register updates causing false unwanted dependencies. The ExecutionDepsFix pass will break the false dependencies if the updated register was written in the previoius N instructions.

* Under the hood, MBPI is doing a linear scan of every successor everyChandler Carruth2011-11-14
| | | | | | | | | | | | | | | | | | time it is queried to compute the probability of a single successor. This makes computing the probability of every successor of a block in sequence... really really slow. ;] This switches to a linear walk of the successors rather than a quadratic one. One of several quadratic behaviors slowing this pass down. I'm not really thrilled with moving the sum code into the public interface of MBPI, but I don't (at the moment) have ideas for a better interface. My direction I'm thinking in for a better interface is to have MBPI actually retain much more state and make *all* of these queries cheap. That's a lot of work, and would require invasive changes. Until then, this seems like the least bad (ie, least quadratic) solution. Suggestions welcome. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144530 91177308-0d34-0410-b5e6-96231b3b80d8
* Reuse the logic in getEdgeProbability within getHotSucc in order toChandler Carruth2011-11-14
| | | | | | | | | | correctly handle blocks whose successor weights sum to more than UINT32_MAX. This is slightly less efficient, but the entire thing is already linear on the number of successors. Calling it within any hot routine is a mistake, and indeed no one is calling it. It also simplifies the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144527 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix an overflow bug in MachineBranchProbabilityInfo. This pass relied onChandler Carruth2011-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | the sum of the edge weights not overflowing uint32, and crashed when they did. This is generally safe as BranchProbabilityInfo tries to provide this guarantee. However, the CFG can get modified during codegen in a way that grows the *sum* of the edge weights. This doesn't seem unreasonable (imagine just adding more blocks all with the default weight of 16), but it is hard to come up with a case that actually triggers 32-bit overflow. Fortuately, the single-source GCC build is good at this. The solution isn't very pretty, but its no worse than the previous code. We're already summing all of the edge weights on each query, we can sum them, check for an overflow, compute a scale, and sum them again. I've included a *greatly* reduced test case out of the GCC source that triggers it. It's a pretty lame test, as it clearly is just barely triggering the overflow. I'd like to have something that is much more definitive, but I don't understand the fundamental pattern that triggers an explosion in the edge weight sums. The buggy code is duplicated within this file. I'll colapse them into a single implementation in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144526 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename SlotIndexes to match how they are used.Jakob Stoklund Olesen2011-11-13
| | | | | | | | | | | | | | | | | | | | The old naming scheme (load/use/def/store) can be traced back to an old linear scan article, but the names don't match how slots are actually used. The load and store slots are not needed after the deferred spill code insertion framework was deleted. The use and def slots don't make any sense because we are using half-open intervals as is customary in C code, but the names suggest closed intervals. In reality, these slots were used to distinguish early-clobber defs from normal defs. The new naming scheme also has 4 slots, but the names match how the slots are really used. This is a purely mechanical renaming, but some of the code makes a lot more sense now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144503 91177308-0d34-0410-b5e6-96231b3b80d8
