* [PowerPC] Add predicted forms of branchesUlrich Weigand2013-06-247-68/+1395
| | | | | | | | | | | | | | | | | | | | | | This adds support for the predicted forms of branches (+/-). There are three cases to consider: - Branches using a PPC::Predicate code For these, I've added new PPC::Predicate codes corresponding to the BO values for predicted branch forms, and updated insn printing to print them correctly. I've also added new aliases for the asm parser matching the new forms. - bt/bf I've added new aliases matching to gBC etc. - bd(n)z variants I've added new instruction patterns for the predicted forms. In all cases, the new patterns are used for the asm parser only. (The new infrastructure ought to be sufficient to allow use by the compiler too at some point.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184754 91177308-0d34-0410-b5e6-96231b3b80d8

"LoopVectorize: Use the dependence test utility class We now no longer need alias analysis - the cases that alias analysis would handle are now handled as accesses with a large dependence distance. We can now vectorize loops with simple constant dependence distances. for (i = 8; i < 256; ++i) { a[i] = a[i+4] * a[i+8]; } for (i = 8; i < 256; ++i) { a[i] = a[i-4] * a[i-8]; } We would be able to vectorize about 200 more loops (in many cases the cost model instructs us no to) in the test suite now.

* [PowerPC] Support generic conditional branches in asm parserUlrich Weigand2013-06-243-9/+84
| | | | | | | | | | | | | This adds instruction patterns to cover the generic forms of the conditional branch instructions. This allows the assembler to support the generic mnemonics. The compiler will still generate the various specific forms of the instruction that were already supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184722 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Support absolute branchesUlrich Weigand2013-06-2414-76/+344
| | | | | | | | | | | | | | | | | | | | There is currently only limited support for the "absolute" variants of branch instructions. This patch adds support for the absolute variants of all branches that are currently otherwise supported. This requires adding new fixup types so that the correct variant of relocation type can be selected by the object writer. While the compiler will continue to usually choose the relative branch variants, this will allow the asm parser to fully support the absolute branches, with either immediate (numerical) or symbolic target addresses. No change in code generation intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184721 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | only access the significand of FiniteNonZero/NaN floats. The method significandParts() is a helper method meant to ease access to APFloat's significand by allowing the user to not need to be aware of whether or not the APFloat is using memory allocated in the instance itself or in an external array. This assert says that one can only access the significand of FiniteNonZero/NaN floats. This makes it cumbersome and more importantly dangerous when one wishes to zero out the significand of a zero/infinity value since one will have to deal with the aforementioned quandary related to how the memory in APFloat is allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184711 91177308-0d34-0410-b5e6-96231b3b80d8

In the context of APFloat, seeing a macro called convolve suggests that APFloat is using said value in some sort of convolution somewhere in the source code. This is misleading.
