2015-12-20[PGO] Improve Indexed Profile Reader efficiency Xinliang David Li7-151/+176
With the support of value profiling added, the Indexed prof reader gets less efficient. The prof reader initialization used to be just reading the file header, but with VP support added, initialization needs to walk through all profile keys of ondisk hash table resulting in very poor locality and large memory increase (keys are stored together with the profile data in the mapped profile buffer). Even worse, when the reader is used by the compiler (not llvm-profdata too), the penalty becomes very high as compilation of each single module requires touching profile data buffer for the whole program. In this patch, the icall target values (MD5hash) are no longer eargerly converted back to name strings when the data is read into memory. New interface is added to to profile reader so that InstrProfSymtab can be lazily created for Indexed profile reader on-demand. Creating of the symtab is intended to be used by llvm-profdata tool for symbolic dumping of VP data. It can be used with compiler (for legacy out of tree uses) too but not recommended due to compile time and memory reasons mentioned above. Some other cleanups are also included: Function Addr to md5 map is now consolated into InstrProfSymtab. InstrProfStringtab is no longer used and eliminated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@256114 91177308-0d34-0410-b5e6-96231b3b80d8

2015-12-19[RS4GC] Remove an overly strong assertionPhilip Reames2-10/+40
As shown by the included test case, it's reasonable to end up with constant references during base pointer calculation. The code actually handled this case just fine, we only had the assert to help isolate problems under the belief that constant references shouldn't be present in IR generated by managed frontends. This turned out to be wrong on two fronts: 1) Manual Jacobs is working on a language with constant references, and b) we found a case where the optimizer does create them in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@256079 91177308-0d34-0410-b5e6-96231b3b80d8
2015-12-19Clean up the processing of dbg.value in various placesKeno Fischer13-43/+138
Summary: First up is instcombine, where in the dbg.declare -> dbg.value conversion, the llvm.dbg.value needs to be called on the actual loaded value, rather than the address (since the whole point of this transformation is to be able to get rid of the alloca). Further, now that that's cleaned up, we can remove a hack in the backend, that would add an implicit OP_deref if the argument to dbg.value was an alloca. This stems from before the existence of DIExpression and is no longer necessary since the deref can be expressed explicitly. Now, in order to make sure that the tests pass with this change, we need to correct the printing of DEBUG_VALUE comments to take into account the expression, which wasn't taken into account before. Unfortunately, for both these changes, there were a number of incorrect test cases (mostly the wrong number of DW_OP_derefs, but also a couple where the test itself was broken more badly). aprantl and I have gone through and adjusted these test case in order to make them pass with these fixes and in some cases to make sure they're actually testing what they are meant to test.

2015-12-19AMDGPU: fix overlapping copies in copyPhysRegNicolai Haehnle3-14/+32
Summary: When copying aggregate registers within the same register class, there may be an overlap between source and destination that forces us to do the copy backwards. Do the simplest possible thing that guarantees the correct order of moves when there are overlaps, and does whatever when there is no overlap. (The last part forces some trivial adjustments to test cases.) Together with r255906, this fixes a VM fault in Unreal Elemental Demo. While at it, change the generation of kill and def flags to something that looks more reasonable. This method is used very late during compilation, so it probably doesn't matter in practice, and to be honest, I don't know if this change is actually correct because the semantics in connection with aggregate registers vs. sub-registers are not clear to me.
