Summary: We currently don't support offsetof in the expression evaluator as it is implemented as a macro (which then calls __builtin_offsetof) in stddef.h. The best solution would be to include that header (or even better, import Clang's builtin module), but header-parsing and (cross-platform) importing modules is not ready yet. Until we get this working with modules I would say we add the macro to our existing macro list as we already do with other macros from stddef.h/stdint.h. We should be able to drop all of them once we can import the relevant modules by default. rdar://26040641 Reviewers: shafik, davide Reviewed By: davide Subscribers: clayborg, lldb-commits Tags: #lldb Differential Revision: https://reviews.llvm.org/D64917 llvm-svn: 366476
