2013-03-18Register the flush function for each compile unit.Bill Wendling
For each compile unit, we want to register a function that will flush that compile unit. Otherwise, __gcov_flush() would only flush the counters within the current compile unit, and not any outside of it.

2013-03-18Fix PPC unaligned 64-bit loads and storesHal Finkel
PPC64 supports unaligned loads and stores of 64-bit values, but in order to use the r+i forms, the offset must be a multiple of 4. Unfortunately, this cannot always be determined by examining the immediate itself because it might be available only via a TOC entry. In order to get around this issue, we additionally predicate the selection of the r+i form on the alignment of the load or store (forcing it to be at least 4 in order to select the r+i form). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177338 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-18ARM cost model: Make some vector integer to float casts cheaperArnold Schwaighofer
The default logic marks them as too expensive. For example, before this patch we estimated: cost of 16 for instruction: %r = uitofp <4 x i16> %v0 to <4 x float> While this translates to: vmovl.u16 q8, d16 vcvt.f32.u32 q8, q8 All other costs are left to the values assigned by the fallback logic. Theses costs are mostly reasonable in the sense that they get progressively more expensive as the instruction sequences emitted get longer. radar://13445992 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177334 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-18ARM cost model: Correct cost for some cheap float to integer conversionsArnold Schwaighofer
Fix cost of some "cheap" cast instructions. Before this patch we used to estimate for example: cost of 16 for instruction: %r = fptoui <4 x float> %v0 to <4 x i16> While we would emit: vcvt.s32.f32 q8, q8 vmovn.i32 d16, q8 vuzp.8 d16, d17 All other costs are left to the values assigned by the fallback logic. Theses costs are mostly reasonable in the sense that they get progressively more expensive as the instruction sequences emitted get longer. radar://13434072 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177333 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-18Change test cases to handle unaligned references.Bill Schmidt
Hal Finkel recently added code to allow unaligned memory references for PowerPC. Two tests were temporarily modified with -disable-ppc-unaligned to keep them from failing.

We hitch a ride with the existing OpndItins class that was used to add instruction itinerary classes in the many multiclasses in this file. Use the link provided by the X86FoldableSchedWrite.Folded to find the right SchedWrite for folded loads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177326 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-18Annotate X86 arithmetic instructions with SchedRW lists.Jakob Stoklund Olesen
This new-style scheduling information is going to replace the instruction iteneraries. This also serves as a test case for Andy's fix in r177317. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177323 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-18Check whether a pointer is non-null (isKnownNonNull) in isKnownNonZero.Manman Ren
This handles the case where we have an inbounds GEP with alloca as the pointer. This fixes the regression in PR12750 and rdar://13286434. Note that we can also fix this by handling some GEP cases in isKnownNonNull. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177321 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-18Include '.test' suffix in target specific lit configs that need itDavid Blaikie
Apparently my final cleanup to use a relevant suffix for these tests before committing r176831 caused them to stop running since lit wasn't configured to run tests with that suffix in those directories (why don't we just have a global suffix list?). So, add the suffix to the relevant directories & fix the test that has bitrotted over the last week due to my debug info schema changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177315 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-18Fix large count and negative constant count handling in PPCCTRLoopsHal Finkel
This commit fixes an assert that would occur on loops with large constant counts (like looping for ((uint32_t) -1) iterations on PPC64). The existing code did not handle counts that it computed to be negative (asserting instead), but these can be created with valid inputs. This bug was discovered by bugpoint while I was attempting to isolate a completely different problem. Also, in writing test cases for the negative-count problem, I discovered that the ori/lsi handling was broken (there was a typo which caused the logic that was supposed to detect these pairs and extract the iteration count to always fail). This has now also been corrected (and is covered by one of the new test cases). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177295 91177308-0d34-0410-b5e6-96231b3b80d8
