r? lqd Good find and a good cleanup. Since this is two consecutive moves though, can you squash the first two commits? Reading them made me believe we had this code duplicated at first. r=me with that done and ci green |
…llvm Don't export them from cdylibs. There is no need to do so and it complicates exported_non_generic_symbols. In addition the GCC backend likely uses different symbols and may potentially not even need us to explicitly tell it to export the symbols it needs.
All other sanitizer symbols are handled in prepare_lto already.

Rollup merge of #145965 - bjorn3:sanitize_symbol_export_improvements, r=lqd Move exporting of profiler and sanitizer symbols to the LLVM backend Only the LLVM backend needs those specific symbols exported and it only needs them to be exported for LTO, not from cdylibs in general.
