* The 'optnone' attribute means don't inline anything into this functionPaul Robinson2013-11-181-2/+3
| | | | | | | | | | | (except functions marked always_inline). Functions with 'optnone' must also have 'noinline' so they don't get inlined into any other function.

* Remove linkonce_odr_auto_hide.Rafael Espindola2013-11-011-10/+3
| | | | | | | | | | | | | | | linkonce_odr_auto_hide was in incomplete attempt to implement a way for the linker to hide symbols that are known to be available in every TU and whose addresses are not relevant for a particular DSO. It was redundant in that it all its uses are equivalent to linkonce_odr+unnamed_addr. Unlike those, it has never been connected to clang or llvm's optimizers, so it was effectively dead. Given that nothing produces it, this patch just nukes it (other than the llvm-c enum value). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193865 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a llvm.copysign intrinsicHal Finkel2013-08-191-0/+36
| | | | | | | | | | | | | | | | | | | | | This adds a llvm.copysign intrinsic; We already have Libfunc recognition for copysign (which is turned into the FCOPYSIGN SDAG node). In order to autovectorize calls to copysign in the loop vectorizer, we need a corresponding intrinsic as well. In addition to the expected changes to the language reference, the loop vectorizer, BasicTTI, and the SDAG builder (the intrinsic is transformed into an FCOPYSIGN node, just like the function call), this also adds FCOPYSIGN to a few lists in LegalizeVector{Ops,Types} so that vector copysigns can be expanded. In TargetLoweringBase::initActions, I've made the default action for FCOPYSIGN be Expand for vector types. This seems correct for all in-tree targets, and I think is the right thing to do because, previously, there was no way to generate vector-values FCOPYSIGN nodes (and most targets don't specify an action for vector-typed FCOPYSIGN). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188728 91177308-0d34-0410-b5e6-96231b3b80d8

* Add ISD::FROUND for libm round()Hal Finkel2013-08-071-0/+36
| | | | | | | | | | | | | | | All libm floating-point rounding functions, except for round(), had their own ISD nodes. Recent PowerPC cores have an instruction for round(), and so here I'm adding ISD::FROUND so that round() can be custom lowered as well. For the most part, this is straightforward. I've added an intrinsic and a matching ISD node just like those for nearbyint() and friends. The SelectionDAG pattern I've named frnd (because ISD::FP_ROUND has already claimed fround). This will be used by the PowerPC backend in a follow-up commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187926 91177308-0d34-0410-b5e6-96231b3b80d8
