2013-04-30LocalStackSlotAllocation improvementsHal Finkel
First, taking advantage of the fact that the virtual base registers are allocated in order of the local frame offsets, remove the quadratic register-searching behavior. Because of the ordering, we only need to check the last virtual base register created. Second, store the frame index in the FrameRef structure, and get the frame index and the local offset from this structure at the top of the loop iteration. This allows us to de-nest the loops in insertFrameReferenceRegisters (and I think makes the code cleaner). I also moved the needsFrameBaseReg check into the first loop over instructions so that we don't bother pushing FrameRefs for instructions that don't want a virtual base register anyway. Lastly, and this is the only functionality change, avoid the creation of single-use virtual base registers. These are currently not useful because, in general, they end up replacing what would be one r+r instruction with an add and a r+i instruction.

2013-04-29Use unique'ed types for varargs expansion instead of non-unique named types.Jan Voung
Saves a tiny bit of space for var-args heavy bitcode programs, since the anonymous types get unique'ed. E.g., saves 20KB out of 1.6MB in spec gcc when comparing the gzipped files, or about 100KB when not zipped. This is only a savings with the current wire format. If we change the alloca, etc. to only have sizes and not struct types then we would also not have this duplication. Just happened to notice while looking through code for what struct types remain used in the bitcode. random cleanup for: BUG= https://code.google.com/p/nativeclient/issues/detail?id=3338 R=mseaborn@chromium.org Review URL: https://codereview.chromium.org/14197004

- Revise previous patches of the same purpose by fixing *) grep <PA> | not grep <PB> semantically is not the same as CHECK: <PA>{{^<PB>.*$}} as the former will check all occurrences of <PA> while the later only check the first match. As the result, CHECK needs putting in all place where <PA> occurs. *) grep <PA> | count <N> needs a final CHECK-NOT of the same pattern. (As 'CHECK-<N>' is proposed for discussion, converting 'grep | count <N>' where N > 1 is postponed.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180742 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola
For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-29SimplifyCFG: If convert single conditional storesArnold Schwaighofer
This resurrects r179957, but adds code that makes sure we don't touch atomic/volatile stores: This transformation will transform a conditional store with a preceeding uncondtional store to the same location: a[i] = may-alias with a[i] load if (cond) a[i] = Y into an unconditional store. a[i] = X may-alias with a[i] load tmp = cond ? Y : X; a[i] = tmp We assume that on average the cost of a mispredicted branch is going to be higher than the cost of a second store to the same location, and that the secondary benefits of creating a bigger basic block for other optimizations to work on outway the potential case where the branch would be correctly predicted and the cost of the executing the second store would be noticably reflected in performance. hmmer's execution time improves by 30% on an imac12,2 on ref data sets. With this change we are on par with gcc's performance (gcc also performs this transformation). There was a 1.2 % performance improvement on a ARM swift chip. Other tests in the test-suite+external seem to be mostly uninfluenced in my experiments: This optimization was triggered on 41 tests such that the executable was different before/after the patch. Only 1 out of the 40 tests (dealII) was reproducable below 100% (by about .4%). Given that hmmer benefits so much I believe this to be a fair trade off. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180731 91177308-0d34-0410-b5e6-96231b3b80d8

Solves the problem of a module with no triple on the command line and no triple in the module using non-gdb ok features on darwin. Fix up the member-pointers test to check the correct things for cross platform (DW_FORM_flag is a good prefix).
