git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57969 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-22Be nice to CellSPU: for this target getSetCCResultTypeDuncan Sands
may return i8, which can result in SELECT nodes for which the type of the condition is i8, but there are no patterns for select with i8 condition. Tweak the LegalizeTypes logic to avoid this as much as possible. This isn't a real fix because it is still perfectly possible to end up with such select nodes - CellSPU needs to be fixed IMHO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57968 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-22Add some comments explaining the meaning of a booleanDuncan Sands
that is not of type MVT::i1 in SELECT and SETCC nodes. Relax the LegalizeTypes SELECT condition promotion sanity checks to allow other condition types than i1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57966 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-22Temporarily allow the operands of a BUILD_VECTORDuncan Sands
to have a different type to the vector element type. This should be fairly harmless because in the past guys like this were being built all over the place (and were cleaned up when I added this check). The reason for relaxing this check is that it helps LegalizeTypes legalize vector shuffles: the mask is a BUILD_VECTOR that it is *not always possible* to legalize while keeping it a BUILD_VECTOR (vector_shuffle requires the mask to be a BUILD_VECTOR, as opposed to a vector with the right vector type). With this check it is even harder to legalize the mask - turning the check off means that LegalizeTypes manages to legalize almost all vector shuffles encountered in practice. The correct solution is to change vector_shuffle to be a variadic node with the mask built into it as operands. While waiting for that change, this hack stops the problem with vector_shuffle from blocking the turning on of LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57965 91177308-0d34-0410-b5e6-96231b3b80d8

in the 32-bit signed offset field of addresses. Even though this may be intended, some linkers refuse to relocate code where the relocated address computation overflows. Also, fix the sign-extension of constant offsets to use the actual pointer size, rather than the size of the GlobalAddress node, which may be different, for example on x86-64 where MVT::i32 is used when the address is being fit into the 32-bit displacement field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57885 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-21Optimized FCMP_OEQ and FCMP_UNE for x86.Dan Gohman
Where previously LLVM might emit code like this: ucomisd %xmm1, %xmm0 setne %al setp %cl orb %al, %cl jne .LBB4_2 it now emits this: ucomisd %xmm1, %xmm0 jne .LBB4_2 jp .LBB4_2 It has fewer instructions and uses fewer registers, but it does have more branches. And in the case that this code is followed by a non-fallthrough edge, it may be followed by a jmp instruction, resulting in three branch instructions in sequence. Some effort is made to avoid this situation. To achieve this, X86ISelLowering.cpp now recognizes FCMP_OEQ and FCMP_UNE in lowered form, and replace them with code that emits two branches, except in the case where it would require converting a fall-through edge to an explicit branch. Also, X86InstrInfo.cpp's branch analysis and transform code now knows now to handle blocks with multiple conditional branches. It uses loops instead of having fixed checks for up to two instructions. It can now analyze and transform code generated from FCMP_OEQ and FCMP_UNE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57873 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-21When the coalescer is doing rematerializing, have it removeDan Gohman
the copy instruction from the instruction list before asking the target to create the new instruction. This gets the old instruction out of the way so that it doesn't interfere with the target's rematerialization code. In the case of x86, this helps it find more cases where EFLAGS is not live. Also, in the X86InstrInfo.cpp, teach isSafeToClobberEFLAGS to check to see if it reached the end of the block after scanning each instruction, instead of just before. This lets it notice when the end of the block is only two instructions away, without doing any additional scanning. These changes allow rematerialization to clobber EFLAGS in more cases, for example using xor instead of mov to set the return value to zero in the included testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57872 91177308-0d34-0410-b5e6-96231b3b80d8
