History

Adrian Prantl a8b2ddbde4 Move the stripping of invalid debug info from the Verifier to AutoUpgrade. 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. Differential Revision: https://reviews.llvm.org/D38184 llvm-svn: 314699		2017-10-02 18:31:29 +00:00

This directory contains testcases that the verifier is supposed to detect as
malformed LLVM code.  Testcases for situations that the verifier incorrectly
identifies as malformed should go in the test/Assembler directory.
