[cfe-users] libclang: generating pretokenized headers

[Miguel Guedes]

Hello List,

Can pretokenized headers be generated using libclang? I've had a look at 
the page on pretokenized headers [0] but there's no mention to libclang 
at all. Bad omen?

Also, would using pretokenized headers help reducing the time it takes to 
parse an AST with libclang or does it drop any `-include-pth' options 
passed to clang_parseTranslationUnit?

This seems like a wonderful feature as I'm seeing parsing times of over 7 
seconds per source file, however I'd rather hear from an expert on 
(lib)clang's internals before moving ahead and implementing this feature.
