Hi guys,
I am working on http://llvm.org/bugs/show_bug.cgi?id=20507 Now the
diagnostic gets issued for:
Clang :: Modules/declare-use1.cpp
Clang :: Modules/declare-use2.cpp
Clang :: Modules/declare-use3.cpp
Clang :: Modules/strict-decluse.cpp
It says smth like: Modules/Inputs/declare-use/module.map:30:10: note:
Header file 'unavailable.h' not present in module 'XF'
I'd like to add an expected diag to the modulemap file. Eg:
module XF {
...
header "unavailable.h" // expected-note {{...}}
...
}
Is that the right way to go?
If yes, VerifyDiagnosticConsumer requires some callbacks (such as
HandleComment) which come from the Preprocessor. In the ModuleMapParser
we use raw lexing (without PP at all) and I was wondering what would be
the right way to go, in order to make the -verify flag work inside the
module maps. One solution that I see is to pass the comment handlers
from the PP to the ModuleMapParser, however IMO this would break the
encapsulation. Do you have better ideas?
Many thanks,
Vassil
