When an internal-linkage thunk is code gen'd, CodeGenVTables::emitThunk will first be called with ForVTable=true (which incorrectly set the thunk's linkage to available_externally under the Itanium ABI) and later with ForVTable=false (which reset it to internal). Because we will always see a call with ForVTable=false, this incorrect linkage never ended up in the final IR. However, the temporary presence of this linkage caused us to give such functions a comdat as a result of code introduced in r241102. To avoid this, check that the thunk is externally visible before giving it available_externally linkage. llvm-svn: 241136 |
