Add a helper function getDebugInfoVersionFromModule to return the debug info version number for a module. "Verifier/module-flags-1.ll" checks for verification errors. It will seg fault when calling getDebugInfoVersionFromModule because of the incorrect format for module flags in the testing case. We make getModuleFlagsMetadata more robust by checking for error conditions.

* Remove linkonce_odr_auto_hide.Rafael Espindola2013-11-011-1/+0
| | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | Reviewed by Joe Abbey and Tobias Grosser Here is a patch that fixes decoding of CE_SELECT in BitcodeReader, along with a simple test case. The problem in the current code is that it generates but doesn't accept bitcode that uses vectors for the first element of a select in this context. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190634 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert patches to add case-range support for PR1255.Bob Wilson2013-09-091-11/+16
| | | | | | | | | | | | | | | | | The work on this project was left in an unfinished and inconsistent state. Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were. I have left support in the bitcode reader to handle the case-range bitcode format, so that we do not lose bitcode compatibility with the llvm 3.3 release.

* Make .bc en/decoding of AttrKind stableTobias Grosser2013-07-261-2/+130
| | | | | | | | | | | | | | | | The bitcode representation attribute kinds are encoded into / decoded from should be independent of the current set of LLVM attributes and their position in the AttrKind enum. This patch explicitly encodes attributes to fixed bitcode values. With this patch applied, LLVM does not silently misread attributes written by LLVM 3.3. We also enhance the decoding slightly such that an error message is printed if an unknown AttrKind encoding was dected. Bonus: Dropping bitcode attributes from AttrKind is now easy, as old AttrKinds do not need to be kept to support the Bitcode reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187186 91177308-0d34-0410-b5e6-96231b3b80d8

This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM.

The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today.
