Hi everyone,<br><br>I found some peculiar behavior of TableGen when generating [TARGET]GenRegisterInfo.inc. Some register overlaps are generated twice in this file, leading to a compilation error. I think this is because in RegisterInfoEmitter.cpp, RegisterAliases are declared as "std::map<Record*, std::set<Record*>, LessRecord>"<br>
<br>and a requirement for std::map is that the comparison function ("LessRecord") should correspond to a strict weak ordering; in this case this points to : <br><br> "StringRef1.compare_numeric(StringRef2) < 0"<br>
<br>which does not behave like strict weak ordering predicate on the set of strings. I have attached an example built upon snippets from StringRef.cpp, compiled with gcc version 4.4.5 (Debian 4.4.5-8) (I also saw that there is a workaround for gcc 4.x ...). <br>
<br>Please tell me if I am doing something wrong or this is a real bug. <br><br>Thank you,<br>Alex<br><br>
