In the case of the atos symbolizer, atos might not report thefunction offset (e.g. it reports a source location instead) so in thiscase it fallsback to using `dladdr()` to compute the function offset.Two test cases are included.rdar://problem/56695185Reviewers: kubamracek, ylnSubscribers: #sanitizers, llvm-commitsTags: #sanitizers, #llvmDifferential Revision: https://reviews.llvm.org/D69549 List of files: /llvm-project-15.0.7/compiler-rt/test/sanitizer_common/TestCases/Darwin/symbolizer-function-offset-dladdr.cpp Tue, 29 Oct 2019 06:04:27 +0000 Dan Liew <dan@su-root.co.uk>
