...defined a set of registers with rather similar names including digits. The code section at RegisterInfoEmitter::run(){ ... // Process sub-register sets. runs and fills the RegisterAliases map. then, ... for (unsigned i = 0, e = Regs.size(); i != e; ++i) { RegNo[Regs[i].TheDef] = i; NumAliases += RegisterAliases[Regs[i].TheDef].size(); } runs. Only, now there are duplicates in the RegisterAliases map for the same Regs[i]-Record. This lead to duplicate output of the REG_Overlaps lists: error: redefinition of 'const unsigned int llvm::<unnamed>::a23g_Overlaps []' /local/sc...
