2013-04-07Cleanup and improve PPC fsel generationHal Finkel
First, we should not cheat: fsel-based lowering of select_cc is a finite-math-only optimization (the ISA manual, section F.3 of v2.06, makes this clear, as does a note in our own README). This also adds fsel-based lowering of EQ and NE condition codes. As it turned out, fsel generation was covered by a grand total of zero regression test cases. I've added some test cases to cover the existing behavior (which is now finite-math only), as well as the new EQ cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179000 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-07TargetLowering: Fix getTypeConversion handling of extended vector typesArnold Schwaighofer
The code in getTypeConversion attempts to promote the element vector type before it trys to split or widen the vector. After it failed finding a legal vector type by promoting it would continue using the promoted vector element type. Thereby missing legal splitted vector types. For example the type v32i32 that has a legal split of 4 x v3i32 on x86/sse2 would be transformed to: v32i256 and from there on successively split to: v16i256, v8i256, v1i256 and then finally ends up as an i64 type. By resetting the vector element type to the original vector element type that existed before the promotion the code will attempt to split the vector type to smaller vector widths of the same type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178999 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-07Fix PR15674 (and PR15603): a SROA think-o.Chandler Carruth
The fix for PR14972 in r177055 introduced a real think-o in the *store* side, likely because I was much more focused on the load side. While we can arbitrarily widen (or narrow) a loaded value, we can't arbitrarily widen a value to be stored, as that changes the width of memory access! Lock down the code path in the store rewriting which would do this to only handle the intended circumstance. All of the existing tests continue to pass, and I've added a test from the PR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178974 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-06Implement LowerReturn_64 for SPARC v9.Jakob Stoklund Olesen
Integer return values are sign or zero extended by the callee, and structs up to 32 bytes in size can be returned in registers. The CC_Sparc64 CallingConv definition is shared between LowerFormalArguments_64 and LowerReturn_64. Function arguments and return values are passed in the same registers. The inreg flag is also used for return values. This is required to handle C functions returning structs containing floats and ints: struct ifp { int i; float f; }; struct ifp f(void); LLVM IR: define inreg { i32, float } @f() { ... ret { i32, float } %retval } The ABI requires that %retval.i is returned in the high bits of %i0 while %retval.f goes in %f1. Without the inreg return value attribute, %retval.i would go in %i0 and %retval.f would go in %f3 which is a more efficient way of returning %multiple values, but it is not ABI compliant for returning C structs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178966 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-06SPARC v9 stack pointer bias.Jakob Stoklund Olesen
64-bit SPARC v9 processes use biased stack and frame pointers, so the current function's stack frame is located at %sp+BIAS .. %fp+BIAS where BIAS = 2047. This makes more local variables directly accessible via [%fp+simm13] addressing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178965 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-06Implement PPCInstrInfo::FoldImmediateHal Finkel
There are certain PPC instructions into which we can fold a zero immediate operand. We can detect such cases by looking at the register class required by the using operand (so long as it is not otherwise constrained). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178961 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-06Complete formal arguments for the SPARC v9 64-bit ABI.Jakob Stoklund Olesen
All arguments are formally assigned to stack positions and then promoted to floating point and integer registers. Since there are more floating point registers than integer registers, this can cause situations where floating point arguments are assigned to registers after integer arguments that where assigned to the stack. Use the inreg flag to indicate 32-bit fragments of structs containing both float and int members. The three-way shadowing between stack, integer, and floating point registers requires custom argument lowering. The good news is that return values are passed in the exact same way, and we can share the code. Still missing: - Update LowerReturn to handle structs returned in registers. - LowerCall. - Variadic functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178958 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-05R600/SI: Use same names for corresponding MUBUF operands and encoding fieldsTom Stellard
The code emitter knows how to encode operands whose name matches one of the encoding fields. If there is no match, the code emitter relies on the order of the operand and field definitions to determine how operands should be encoding. Matching by order makes it easy to accidentally break the instruction encodings, so we prefer to match by name.
