* llvm-cov: Ignore missing .gcda filesJustin Bogner2014-02-04
| | | | | | | | When gcov is run without gcda data, it acts as if the counts are all zero and labels the file as - to indicate that there was no data. We should do the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200740 91177308-0d34-0410-b5e6-96231b3b80d8

* inalloca: Don't remove dead arguments in the presence of inalloca argsReid Kleckner2014-02-03
| | | | | | | | | | | | It disturbs the layout of the parameters in memory and registers, leading to problems in the backend. The plan for optimizing internal inalloca functions going forward is to essentially SROA the argument memory and demote any captured arguments (things that aren't trivially written by a load or store) to an indirect pointer to a static alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200717 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64 & ARM: refactor crypto intrinsics to take scalarsTim Northover2014-02-03
| | | | | | | | | | | | Some of the SHA instructions take a scalar i32 as one argument (largely because they work on 160-bit hash fragments). This wasn't reflected in the IR previously, with ARM and AArch64 choosing different types (<4 x i32> and <1 x i32> respectively) which was ugly. This makes all the affected intrinsics take a uniform "i32", allowing them to become non-polymorphic at the same time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200706 91177308-0d34-0410-b5e6-96231b3b80d8

* Rename the non-templated base class of SmallPtrSet toChandler Carruth2014-02-03

This more closely matches the organization of SmallVector and should allow introducing a SmallPtrSetImpl which serves the same purpose as SmallVectorImpl: isolating the element type from the particular small size chosen.

* MC: Add AsmLexer::BigNum token for integers greater than 64 bitsDavid Woodhouse2014-02-01
| | | | | | | | | | | | | | | | | | | | This will be needed for .octa support, but we don't want to just use the existing AsmLexer::Integer for it and then have to litter all its users with explicit checks for the size, and make them use the new get APIntVal() method. So let the lexer produce an AsmLexer::Integer as before for numbers which are small enough — which appears to cover what was previously a nasty special case handling of numbers which don't fit in int64_t but *do* fit in uint64_t. Where the number is too large even for that, produce an AsmLexer::BigNum instead. We do nothing with these except complain about them for now, but that will be changed shortly...

* [LPM] Apply a really big hammer to fix PR18688 by recursively reformingChandler Carruth2014-02-01
| | | | | | | | | | | | | | | | | | | | LCSSA when we promote to SSA registers inside of LICM. Currently, this is actually necessary. The promotion logic in LICM uses SSAUpdater which doesn't understand how to place LCSSA PHI nodes. Teaching it to do so would be a very significant undertaking. It may be worthwhile and I've left a FIXME about this in the code as well as starting a thread on llvmdev to try to figure out the right long-term solution. For now, the PR needs to be fixed. Short of using the promition SSAUpdater to place both the LCSSA PHI nodes and the promoted PHI nodes, I don't see a cleaner or cheaper way of achieving this. Fortunately, LCSSA is relatively lazy and sparse -- it should only update instructions which need it. We can also skip the recursive variant when we don't promote to SSA values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200612 91177308-0d34-0410-b5e6-96231b3b80d8

* [inliner] Skip debug intrinsics even earlier in computing the inlineChandler Carruth2014-02-01
| | | | | | | | | | | | | | | | | | | | | | | cost so that they don't impact the vector bonus. Fundamentally, counting unsimplified instructions is just *wrong*; it will continue to introduce instability as things which do not generate code bizarrely impact inlining. For example, sufficiently nested inlined functions could turn off the vector bonus with lifetime markers just like the debug intrinsics do. =/ This is a short-term tactical fix. Long term, I think we need to remove the vector bonus entirely. That's a separate patch and discussion though. The patch to fix this provided by Dario Domizioli. I've added some comments about the planned direction and used a heavily pruned form of debug info intrinsics for the test case. While this debug info doesn't work or "do" anything useful, it lets us easily test all manner of interference easily, and I suspect this will not be the last time we want to craft a pattern where debug info interferes with the inliner in a problematic way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200609 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | This changes the PrologueEpilogInserter and LocalStackSlotAllocation passes to follow the extended stack layout rules for sspstrong and sspreq. The sspstrong layout rules are: 1. Large arrays and structures containing large arrays (>= ssp-buffer-size) are closest to the stack protector. 2. Small arrays and structures containing small arrays (< ssp-buffer-size) are 2nd closest to the protector. 3. Variables that have had their address taken are 3rd closest to the protector.
