commit f0aa1a78fb209310e8baef53c02f365fca518d11
Author: Stephan Bergmann <sberg...@redhat.com>
Date: Fri Feb 27 10:05:22 2015 +0100
For Clang -fsanitize=vptr use -fvisibility-ms-compat, not
-fvisibility=hidden
As discussed in b4f6b26b5a1a78fecfa95ec2eb7ac8b80495d8aa
"SAL_DLLPUBLIC_RTTI for
proper RTTI visibility for LLVM," RTTI-based -fsanitize= checks with Clang
on
Linux need special precautions to make RTTI symbols visible across DSOs.
The
approach taken there, as well as in 598d8194b0ea1a64e0ebba28a86c128bafa57c7c
"Visible function type RTTI for Clang -fsanitize=function," was to add
explicit
SAL_DLLPUBLIC_RTTI annontations to relevant type definitions. However, for
-fsanitize=vptr that would have required many more of those, so it appears
easier to "misuse" -fsanitize-ms-compat in that case, which happens to give
all
RTTI symbols default visibility (while otherwise still honoring our
SAL_DLLPUBLIC/PRIVATE annotations).
The SAL_DLLPUBLIC_RTTI annotations from
598d8194b0ea1a64e0ebba28a86c128bafa57c7c
"Visible function type RTTI for Clang -fsanitize=function" can likely be
removed
again.
