clang package is missing includes

Bug #903509 reported by meh on 2011-12-13

Bug Description

/usr/include/clang/3.0/include/* should be part of 'clang' and not 'libclang-dev', while the other headers are fine in that package (for libclang.so).

These headers contains the SIMD intrinsics like xmmintrin.h
Without libclang-dev clang now includes gcc's version, which in return uses __builtin_*()s.

And that looks like this:

/usr/lib/gcc/x86_64-linux-gnu/4.6/include/xmmintrin.h:102:19: error: use of
undeclared identifier '__builtin_ia32_addss'
return (__m128) __builtin_ia32_addss ((__v4sf)__A, (__v4sf)__B);

Installing libclang-dev fixes this as clang picks those up automatically.

Merge clang 3.0-5 from Debian unstable Edit (15.9 KiB, text/plain)

Here’s an debdiff to merge clang 3.0-5 from unstable. I also fixed the DetectLinuxDistro logic so that it won’t automatically break when precise+1 comes out.

(Not tested yet; it’s currently waiting to build in https://launchpad.net/~anders-kaseorg/+archive/ppa .)

@Anders: Could you please rebase your merge on 3.0-6 (I'm not able to download 3.0-5 anymore) and post the debdiff between Debian and Ubuntu? Generally speaking, it's easier to review for sponsors when you have the diff between Debian and Ubuntu rather than a full Ubuntu -> Ubuntu diff.

Also, I've seen that the control file is generated from files in debian/control.in directory, so update-maintainer fails: you should update debian/control.in/source file with the Ubuntu maintainer.

Thanks for your work!

Sure. But FYI,

Not a regression, but fixed now.

Here’s a diff from 3.0-6.

This bug was fixed in the package clang - 3.0-6ubuntu1

---------------
clang (3.0-6ubuntu1) precise; urgency=low

  * Merge with Debian (LP: #903509); remaining changes:
    - Set Ubuntu as vendor name instead of Debian.
    - Make the `precise' code name known.
    - Update linker flags for `precise'.
    - Set dynamic linker name for armhf, recognize arm-linux-gnueabihf triplet.
    - Remove auto-generated debian_path.h.
  * debian/patches/23-ubuntu-name.diff: Assume unknown Ubuntu releases
    behave like precise, until we know otherwise.

@Anders: By the way, could you please forward the Ubuntu changes to Debian? The one about precise and the one about arm, at least.

Thanks again!

I'm still having the same problem in trusty, I cannot compile any programs with clang as it complains about gcc's vector includes which it shouldn't be using. libclang-dev does not install any files for me either, so I'm not sure what the fix is.
