Bug 10255 – When creating lib files, dmd no longer splits module into multiple obj files

Given: ----- foo.d -------- void foo1() { } void foo2() { } -------------------- and compiling with: dmd -lib foo.d lib -l foo.lib will create the .lst file: ------------------- Publics by name module _D3foo12__ModuleInfoZ foo _D3foo15__unittest_failFiZv foo _D3foo4foo1FZv foo _D3foo4foo2FZv foo _D3foo7__arrayZ foo _D3foo8__assertFiZv foo Publics by module foo _D3foo12__ModuleInfoZ _D3foo15__unittest_failFiZv _D3foo4foo1FZv _D3foo4foo2FZv _D3foo7__arrayZ _D3foo8__assertFiZv --------------------- showing that they are all put in one module. However, dmd -c -multiobj foo.d will correctly create multiple .obj files.

It seems there are actually multiple object files with the same name in the library which are merged in the list file. If you extract a module it only contains some of the listed symbols, not all. Opening the lib in IDA also reveals multiple files with the same name.
