The introduction of `SHF_GNU_RETAIN` has caused massive problems on Solaris. Initially, as reported in Bug 49437, it caused dozens of testsuite failures on both sparc and x86. The objects were marked as `ELFOSABI_NONE`, but `SHF_GNU_RETAIN` is a GNU extension. In the native Solaris ABI, that flag (in the range for OS-specific values) is `SHF_SUNW_ABSENT` with a completely different semantics, which confuses Solaris `ld` very much. Later, the objects became (correctly) marked `ELFOSABI_GNU`, which Solaris `ld` doesn't support, causing it to SEGV and break the build. The linker is currently being hardened to not accept non-native OS ABIs to avoid this. The need for linker support is already documented in `clang/include/clang/Basic/AttrDocs.td`, but not currently checked. This patch avoids all this by not emitting `SHF_GNU_RETAIN` on Solaris at all. Tested on `amd64-pc-solaris2.11`, `sparcv9-sun-solaris2.11`, and `x86_64-pc-linux-gnu`. Differential Revision: https://reviews.llvm.org/D107747 (cherry picked from commit 7bbbf2956181f375ab193321b37ea71c5fc44054) |
