Yes, sorry, I didn't think about it. I investigated the question how can I
remove invalid functions from correction candidate list. But I have a problem
and I hope that you will be able to help me.
I found that the correction is added in function `void
TypoCorrectionConsumer::addName` (in file //SemaLookup.cpp//) which called from
loop in function `std::unique_ptr<TypoCorrectionConsumer>
Sema::makeTypoCorrectionConsumer`. The loop you can see below:
```
// For unqualified lookup, look through all of the names that we have
// seen in this translation unit.
// FIXME: Re-add the ability to skip very unlikely potential corrections.
for (const auto &I : Context.Idents)
Consumer->FoundName(I.getKey());
```
But the map `Context.Idents` already contains names of implicit functions. So,
I found that names of functions were added to this dictionary during parsing
AST. After calling `ConsumeToken()` function in `void
Parser::ParseDeclarationSpecifiers` (in file //ParseDecl.cpp//) implicit
functions were added to the dictionary. But in this function I'm not able to
check is the OpenCL function implicit declared or not.
As a result I tried to remove names of implicit functions before calling
`CorrectTypo`. But unfortunately, we don't have an API for removing items from
`Context.Idents`. So, I don't know the good way for fixing these diagnostic
messages. Could you help me please? Do you have any suggestions?
Thank you in advance!
