2017-10-06Bitcode: add an auto-upgrade for LTO section nameSaleem Abdulrasool
The bitcode reader looks specifically for `__DATA, __objc_catlist` as a section name. However, SVN r304661 removed the spaces (the two names are functionally equivalent but do not compare equally lexicographically). This causes compatibility issues. Add an auto-upgrade path for removing the spaces as well as use the new name in the LTO plugin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@315086 91177308-0d34-0410-b5e6-96231b3b80d8
2017-10-02Move the stripping of invalid debug info from the Verifier to AutoUpgrade.Adrian Prantl
This came out of a recent discussion on llvm-dev (https://reviews.llvm.org/D38042). Currently the Verifier will strip the debug info metadata from a module if it finds the dbeug info to be malformed. This feature is very valuable since it allows us to improve the Verifier by making it stricter without breaking bcompatibility, but arguable the Verifier pass should not be modifying the IR. This patch moves the stripping of broken debug info into AutoUpgrade (UpgradeDebugInfo to be precise), which is a much better location for this since the stripping of malformed (i.e., produced by older, buggy versions of Clang) is a (harsh) form of AutoUpgrade. This change is mostly NFC in nature, the one big difference is the behavior when LLVM module passes are introducing malformed debug info. Prior to this patch, a NoAsserts build would have printed a warning and stripped the debug info, after this patch the Verifier will report a fatal error. I believe this behavior is actually more desirable anyway.

2017-02-15Implement intrinsic mangling for literal struct types.Daniel Berlin
Fixes PR 31921 Summary: Predicateinfo requires an ugly workaround to try to avoid literal struct types due to the intrinsic mangling not being implemented. This workaround actually does not work in all cases (you can hit the assert by bootstrapping with -print-predicateinfo), and can't be made to work without DFS'ing the type (IE copying getMangledStr and using a version that detects if it would crash). Rather than do that, i just implemented the mangling. It seems simple, since they are unified structurally. Looking at the overloaded-mangling testcase we have, it actually turns out the gc intrinsics will *also* crash if you try to use a literal struct. Thus, the testcase added fails before this patch, and works after, without needing to resort to predicateinfo.
