* Stackmaps are used for OSR exits, which is a custom kind of unwinding. ↵Filip Pizlo2014-02-201-0/+1
| | | | | | | | | | | | | | | | | 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. llvm-svn: 201826

* Fix a bug in TableGen where the intrinsic function name recognizer could ↵Justin Holewinski2013-07-251-0/+18
| | | | | | | | | | | | | | | | | 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. llvm-svn: 187119
* Extend 'readonly' and 'readnone' to work on function arguments as well asNick Lewycky2013-07-061-0/+6

* Use the AttributeSet instead of AttributeWithIndex.Bill Wendling2013-01-271-7/+6
| | | | | | | In the future, AttributeWithIndex won't be used anymore. Besides, it exposes the internals of the AttributeSet to outside users, which isn't goodness. llvm-svn: 173606

* Make the AttrListPtr object a part of the LLVMContext.Bill Wendling2012-11-201-1/+1
| | | | | | | | | 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. llvm-svn: 168354
* Remove exception handling usage from tblgen.Joerg Sonnenberger2012-10-251-5/+6
| | | | | | | | | | | 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. llvm-svn: 166712
* Add an enum for the return and function indexes into the AttrListPtr object. ↵Bill Wendling2012-10-151-2/+2
| | | | | | This gets rid of some magic numbers. llvm-svn: 165924
* Attributes RewriteBill Wendling2012-10-151-4/+4
| | | | | | | | | | 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. llvm-svn: 165917
* Pass into the AttributeWithIndex::get method an ArrayRef of attributeBill Wendling2012-10-101-35/+27
