2012-10-25Teach SROA how to split whole-alloca integer loads and stores intoChandler Carruth
smaller integer loads and stores. The high-level motivation is that the frontend sometimes generates a single whole-alloca integer load or store during ABI lowering of splittable allocas. We need to be able to break this apart in order to see the underlying elements and properly promote them to SSA values. The hope is that this fixes some performance regressions on x86-32 with the new SROA pass. Unfortunately, this causes quite a bit of churn in the test cases, and bloats some IR that comes out. When we see an alloca that consists soley of bits and bytes being extracted and re-inserted, we now do some splitting first, before building widened integer "bucket of bits" representations. These are always well folded by instcombine however, so this shouldn't actually result in missed opportunities. If this splitting of all-integer allocas does cause problems (perhaps due to smaller SSA values going into the RA), we could potentially go to some extreme measures to only do this integer splitting trick when there are non-integer component accesses of an alloca, but discovering this is quite expensive: it adds yet another complete walk of the recursive use tree of the alloca. Either way, I will be watching build bots and LNT bots to see what fallout there is here. If anyone gets x86-32 numbers before & after this change, I would be very interested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166662 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-24Fix ODR violations: a virtual function must be defined, even if it's neverRichard Smith
called. Provide an (asserting) definition of Operator's private destructor. Remove destructors from all classes derived from Operator. We don't need them for safety, because their implicit definitions would be ill-formed (they'd call Operator's private destructor), and we don't need them to avoid emitting vtables, because we don't do anything with Operator subclasses which would trigger vtable instantiation. The Operator hierarchy is still a complete disaster with regard to undefined behavior, but this at least allows LLVM to link when using Clang's -fcatch-undefined-behavior with a new vptr-based type checking mechanism. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166530 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-23This is another TLC patch for separating code for the Darwin and ELF ABIsBill Schmidt
for the PowerPC target, and factoring the results. This will ease future maintenance of both subtargets. PPCTargetLowering::LowerCall_Darwin_Or_64SVR4() has grown a lot of special-case code for the different ABIs, making maintenance difficult. This is getting worse as we repair errors in the 64-bit ELF ABI implementation, while avoiding changes to the Darwin ABI logic. This patch splits the routine into LowerCall_Darwin() and LowerCall_64SVR4(), allowing both versions to be significantly simplified. I've factored out chunks of similar code where it made sense to do so. I also performed similar factoring on LowerFormalArguments_Darwin() and LowerFormalArguments_64SVR4(). There are no functional changes in this patch, and therefore no new test cases have been developed. Built and tested on powerpc64-unknown-linux-gnu with no new regressions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166480 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-23Transform code like thisDuncan Sands

This happens all the time in dragonegg, for example for int foo(int *A, int N) { return A[N]; } because gcc turns this into byte pointer arithmetic before it hits the plugin: D.1590_2 = (long unsigned int) N_1(D); D.1591_3 = D.1590_2 * 4; D.1592_5 = A_4(D) + D.1591_3; D.1589_6 = *D.1592_5; return D.1589_6; The D.1592_5 line is a POINTER_PLUS_EXPR, which is turned into a getelementptr on a bitcast of A_4 to i8*, so this becomes exactly the kind of IR that the transform fires on. An analogous transform (with no testcases!) already existed for bitcasts of arrays, so I rewrote it to share code with this one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166474 91177308-0d34-0410-b5e6-96231b3b80d8
