[cfe-dev] problems when compiling FreeBSD world with clang

[Daniel Dunbar]

Hi Roman,

The issue with designated initializers is well known, although not
currently being worked on. See:
http://llvm.org/bugs/show_bug.cgi?id=2749

When I get a moment to do http://llvm.org/bugs/show_bug.cgi?id=3034
(document C status) this will be high on the list.

Wide string support is probably more easily tackled, although it
doesn't look like we have PR for it and no one is working on it as far
as I know. Feel free to file a PR on the issue, preferably with simple
test cases for the cases you care about.

Its great that you are trying to push clang over such a large code
base; thanks for trying this and reporting the issues you find! Do you
have numbers on how many programs we are building (and out of how
many)? And for the programs we build, are you trying to run them
through any kind of tests to make sure we are compiling them
correctly?

 - Daniel
