2012-10-24[ms-inline asm] Create a register operand, rather than a memory operand when weChad Rosier
see the offsetof operator. Previously, we were matching something like MOVrm in the front-end and later matching MOVrr in the back-end. This change makes things more consistent. It also fixes cases where we can't match against a memory operand as the source (test cases coming).

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

2012-10-23[ms-inline asm] When parsing inline assembly we set the base register to aChad Rosier
non-zero value as we don't know the actual value at this point. This is necessary to get the matching correct in some cases. However, the actual value set as the base register doesn't matter, since we're just matching not emitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166523 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
%V = mul i64 %N, 4 %t = getelementptr i8* bitcast (i32* %arr to i8*), i32 %V into %t1 = getelementptr i32* %arr, i32 %N %t = bitcast i32* %t1 to i8* incorporating the multiplication into the getelementptr. 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
