[ELF] - Recommit r273143("[ELF] - Basic versioned symbols support implemented.") With fix: -soname flag was not set in testcase. Hash calculated for base def was different on local and bot machines because filename fos used for calculating. Initial commit message: Patch implements basic support of versioned symbols. There is no wildcards patterns matching except local: *; There is no support for hierarchies. There is no support for symbols overrides (@ vs @@ not handled). This patch allows programs that using simple scripts to link and run. Differential revision: http://reviews.llvm.org/D21018 llvm-svn: 273152
