[cfe-dev] Clang Docs

[Nico Weber]

Hi Tim,

I don't know if there's any documentation for -x.

The list of recognized names is here:
https://llvm.org/viewvc/llvm-project/cfe/trunk/include/clang/Driver/Types.def?view=markup&pathrev=185562It's
a bit long to just include all of that in `clang --help`. (The way I
discovered this was by looking for the "-x" text in
include/clang/Driver/Options.td , then looking for OPT_x in lib/Driver ,
which showed me that Driver.cpp calls types::lookupTypeForTypeSpecifier to
do the string->type transition, and from there I could click me through
clang's oxygen to the Types.td file. clang users shouldn't have to do this
of course, but maybe you're thinking about contributing, then this might be
useful for you.)

clang's user manual is at http://clang.llvm.org/docs/UsersManual.html –
maybe you want to try and contribute documentation for -x? UsersManual.html
is generated from docs/UsersManual.rst in the clang repo.

Nico
