* Intrinsics: add LLVMHalfElementsVectorType constraintTim Northover2014-03-29
| | | | | | | | | | This is like the LLVMMatchType, except the verifier checks that the second argument is a vector with the same base type and half the number of elements. This will be used by the ARM64 backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205079 91177308-0d34-0410-b5e6-96231b3b80d8
* Intrinsics: expand semantics of LLVMExtendedVectorType (& trunc)Tim Northover2014-03-28
| | | | | | | | | | | | These are used in the ARM backends to aid type-checking on patterns involving intrinsics. By making sure one argument is an extended/truncated version of another. However, there's no reason to limit them to just vectors types. For example AArch64 has the instruction "uqshrn sD, dN, #imm" which would naturally use an intrinsic taking an i64 and returning an i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205003 91177308-0d34-0410-b5e6-96231b3b80d8
* Expose "noduplicate" attribute as a property for intrinsics.Eli Bendersky2014-03-18
| | | | | | | | | | | | | | The "noduplicate" function attribute exists to prevent certain optimizations from duplicating calls to the function. This is important on platforms where certain function call duplications are unsafe (for example execution barriers for CUDA and OpenCL). This patch makes it possible to specify intrinsics as "noduplicate" and translates that to the appropriate function attribute. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204200 91177308-0d34-0410-b5e6-96231b3b80d8

* Stackmaps are used for OSR exits, which is a custom kind of unwinding. ↵Filip Pizlo2014-02-20
| | | | | | | | | | | | | | | | | | | Hence, they should not be marked nounwind. Marking them nounwind caused crashes in the WebKit FTL JIT, because if we enable sufficient optimizations, LLVM starts eliding compact_unwind sections (or any unwind data for that matter), making deoptimization via stackmaps impossible. This changes the stackmap intrinsic to be may-throw, adds a test for exactly the sympton that WebKit saw, and fixes TableGen to handle un-attributed intrinsics. Thanks to atrick and philipreames for reviewing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201826 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a bug in TableGen where the intrinsic function name recognizer could ↵Justin Holewinski2013-07-25
| | | | | | | | | | | | | | | | | mis-identify names if one was a prefix substring of the other For two intrinsics 'llvm.nvvm.texsurf.handle' and 'llvm.nvvm.texsurf.handle.internal', TableGen was emitting matching code like: if (Name.startswith("llvm.nvvm.texsurf.handle")) ... if (Name.startswith("llvm.nvvm.texsurf.handle.internal")) ... We can never match "llvm.nvvm.texsurf.handle.internal" here because it will always be erroneously matched by the first condition. The fix is to sort the intrinsic names and emit them in reverse order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187119 91177308-0d34-0410-b5e6-96231b3b80d8

* Make the AttrListPtr object a part of the LLVMContext.Bill Wendling2012-11-20
| | | | | | | | | | When code deletes the context, the AttributeImpls that the AttrListPtr points to are now invalid. Therefore, instead of keeping a separate managed static for the AttrListPtrs that's reference counted, move it into the LLVMContext and delete it when deleting the AttributeImpls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168354 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove exception handling usage from tblgen.Joerg Sonnenberger2012-10-25
| | | | | | | | | | | | Most places can use PrintFatalError as the unwinding mechanism was not used for anything other than printing the error. The single exception was CodeGenDAGPatterns.cpp, where intermediate errors during type resolution were ignored to simplify incremental platform development. This use is replaced by an error flag in TreePattern and bailout earlier in various places if it is set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166712 91177308-0d34-0410-b5e6-96231b3b80d8

* Attributes RewriteBill Wendling2012-10-15
| | | | | | | | | | | Convert the internal representation of the Attributes class into a pointer to an opaque object that's uniqued by and stored in the LLVMContext object. The Attributes class then becomes a thin wrapper around this opaque object. Eventually, the internal representation will be expanded to include attributes that represent code generation options, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165917 91177308-0d34-0410-b5e6-96231b3b80d8
