sivachandra added inline comments.
================
Comment at: libc/utils/HdrGen/Command.h:49
+ llvm::StringRef StdHeader,
+ std::vector<std::string> EntrypointNameList,
+ llvm::RecordKeeper &Records,
----------------
Instead of passing the entrypoint list to all commands, can perhaps pass it to the PublicAPICommand constructor here: https://github.com/llvm/llvm-project/blob/master/libc/utils/HdrGen/Generator.cpp#L43
================
Comment at: libc/utils/HdrGen/Main.cpp:28
+llvm::cl::list<std::string>
+ EntrypointNamesOption("ent", llvm::cl::desc("<list of entrypoints>"),
+ llvm::cl::OneOrMore);
----------------
`desc` should be proper English description. `value_desc` can be what you have listed as `<list of entrypoints>`.
Also, to be consistent with this https://github.com/llvm/llvm-project/blob/master/libc/utils/HdrGen/PrototypeTestGen/PrototypeTestGen.cpp, use just `e` for the option name.
================
Comment at: libc/utils/HdrGen/PublicAPICommand.cpp:92
if (G.FunctionSpecMap.find(Name) == G.FunctionSpecMap.end())
- llvm::PrintFatalError(Name + " not found in any standard spec.\n");
+ continue; // this used to be an error, but isn't anymore because
+ // we're getting the full function list from entrypoints.txt
----------------

Previously the list in `Functions` (or `G.Functions`) was supposed to be identical to that list, but since we're now ignoring what header file we're looking for in `getFunctionsFromEntrypointsFile`, the list `Functions` contains every function listed in `entrypoints.txt`. When I run the code with this as an error it crashes when trying to load a header file because not all functions listed are in that header file.

I think you have not addressed this?
