[LLVMdev] bug in TableGen when generating RegisterInfo?
...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>"
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 :
"StringRef1.compare_numeric(StringRef2) < 0"
which does not behave like strict weak ordering predicate on t...

Hi,
What do you mean "overlapped register"?

Please expose predicates to MachineVerifier
Could we expose predicates defined in the target InstrInfo.td file to the MachineVerifier? We use BuildMI() to create many instructions after ISEL, but the predicates are not being checked at this point. Thus, I could forget to check the target and build an instruction that is illegal for a specific configuration. In such a case it would be nice if the MachineVerifier could detect this for me.

[LLVMdev] Tablegen: RegisterInfoEmitter.cpp
...reviously defined here
This behaved very oddly, as the error disappeared after changing register names from eg a23g to aa23g.
It was the map ordering operator that was the trouble, it seems, as the problem disappeared when I used std::string::compare() instead for
the RegisterAliases map.
struct LessRecord {
bool operator()(const Record *Rec1, const Record *Rec2) const {
return StringRef(Rec1->getName()).compare_numeric(Rec2->getName()) < 0;
}
};
struct LessRecordRegAliases{
bool operator()(const Record *Rec1, const Record *Rec2) const {
return Rec1->getName().compare(Rec2-...
