When a function symbol S has several versions and several different functions with different names have those different versions of S as underlying symbols, libabigail could mistakenly take one function for another. This is because there are cases where libabigail identifies the function using its symbol name without taking the version name into account. This patch fixes that. * src/abg-default-reporter.cc (default_reporter::report): In C, tell the user about the underlying function symbol name only if said symbol name is different from the name of the function. * src/abg-ir.cc (function_decl::get_id): If the function has an underlying symbol, use the symbol name and version as the function ID. But if the function symbol has an alias then use the linkage name as the ID. * tests/data/test-diff-pkg/elfutils-debuginfo-0.170-4.el7.x86_64.rpm: New binary test input. * tests/data/test-diff-pkg/elfutils-debuginfo-0.171-1.el7.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/elfutils-devel-0.170-4.el7.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/elfutils-devel-0.171-1.el7.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/elfutils-libs-0.170-4.el7.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/elfutils-libs-0.171-1.el7.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/elfutils-libs-0.170-4.el7.x86_64-multiple-sym-vers-report-0.txt: New reference test output. * tests/data/Makefile.am: Add the new test material above to source distribution. * tests/test-diff-pkg.cc (in_out_specs): Integrate the new test inputs above into the harness.
