* Allow intrinsics to be used in place of node matchables.Jim Grosbach2012-07-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | TableGen has support for using an intrinics name directly in a DAG, but this breaks down when referring to just a node, as that's handled initializer list stuff entirely via subclassing in the parser. That is, using an instrinsic like "(int_my_intrinsic ...)" works fine. Using it standalone for parameterizing the operator in such a DAG does not. Fixing this is simple enough, as we simply declare Intrinsic as deriving from SDPatternOperator, which is the class name intended for exactly this purpose in TargetSelectionDAG.td. When the intrinsic is actually used in the DAG pattern, it will be recognized and expanded to an intrinsic_wo_chain (et. al.) just like when it's used directly. Incoming ARM NEON cleanup based on this and a bit of functionality improvement after that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159973 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | for NVIDIA PTX 3.0. This back-end will (eventually) replace the current PTX back-end, while maintaining compatibility with it. The new target machines are: nvptx (old ptx32) => 32-bit PTX nvptx64 (old ptx64) => 64-bit PTX The sources are based on the internal NVIDIA NVPTX back-end, and contain more functionality than the current PTX back-end currently provides.

* Switch llvm.cttz and llvm.ctlz to accept a second i1 parameter whichChandler Carruth2011-12-121-2/+2
| | | | | | | | | | | | | | | | | | | | indicates whether the intrinsic has a defined result for a first argument equal to zero. This will eventually allow these intrinsics to accurately model the semantics of GCC's __builtin_ctz and __builtin_clz and the X86 instructions (prior to AVX) which implement them. This patch merely sets the stage by extending the signature of these intrinsics and establishing auto-upgrade logic so that the old spelling still works both in IR and in bitcode. The upgrade logic preserves the existing (inefficient) semantics. This patch should not change any behavior. CodeGen isn't updated because it can use the existing semantics regardless of the flag's value. Note that this will be followed by API updates to Clang and DragonEgg.

| | | | | | | | | | | | duplicate tests are eliminated (for example if the two functions both have a catch clause catching the same type, ensure the redundant one is removed). Note that it would probably be safe to say that eh.typeid.for is 'const', but since two calls to it with the same argument can give different results (but only if the calls are in different functions), it seems more correct to mark it only 'pure'; this doesn't get in the way of the optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139236 91177308-0d34-0410-b5e6-96231b3b80d8
* Split the init.trampoline intrinsic, which currently combines GCC'sDuncan Sands2011-09-061-3/+7
| | | | | | | | | | | | | | | | | | | | | init.trampoline and adjust.trampoline intrinsics, into two intrinsics like in GCC. While having one combined intrinsic is tempting, it is not natural because typically the trampoline initialization needs to be done in one function, and the result of adjust trampoline is needed in a different (nested) function. To get around this llvm-gcc hacks the nested function lowering code to insert an additional parent variable holding the adjust.trampoline result that can be accessed from the child function. Dragonegg doesn't have the luxury of tweaking GCC code, so it stored the result of adjust.trampoline in the memory GCC set aside for the trampoline itself (this is always available in the child function), and set up some new memory (using an alloca) to hold the trampoline. Unfortunately this breaks Go which allocates trampoline memory on the heap and wants to use it even after the parent has exited (!). Rather than doing even more hacks to get Go working, it seemed best to just use two intrinsics like in GCC.

| | | | | | | | | | | | | It needed to be moved closer to the setjmp statement, because the code directly after the setjmp needs to know about values that are on the stack. Also, the 'bitcast' of the function context was causing a dead load. This wouldn't be too horrible, except that at -O0 it wasn't optimized out, and because it wasn't using the correct base pointer (if there is a VLA), it would try to access a value from a garbage address. <rdar://problem/9130540> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128873 91177308-0d34-0410-b5e6-96231b3b80d8
