    mesa: Autogenerate most of format_pack.c
    
    We were auto-generating it before.  The problem was that the autogeneration
    tool we were using was called "copy, paste, and edit".  Let's use a more
    sensible solution.

    - Remove format_pack.c as it is now autogenerated

    - Merge format_convert.py into format_parser.py
       - Adapt pack_*_* function generations
    - Fix out-of-tree build

    - _get_datatype() is now a helper function
    
    v5 by Samuel Iglesias <siglesias@igalia.com>
    - format_pack.c.mako is now format_pack.py, with the template code
      inlined. It now auto-generates format_pack.c
    - Simplify Makefile.am change.
    - Modify SConscript to build format_pack.c with scons.
    - Remove run_mako.py
    - Add format_pack.c to gitignore
    
    v6 by Samuel Iglesias <siglesias@igalia.com>:
    - Don't allow float to non-normalized integer format conversions.
    - Add non-normalized formats support for ubyte packing functions. Merge
    the previously separated patch.
    - Add clamping for non-normalized integer formats in pack_ubyte*()

    - Add assert to check that sRGB formats are 8-bit size.

Weird... I see

> assert(*d >= 0.0f);

in pack_uint_Z_FLOAT32() and pack_uint_Z_FLOAT32_X24S8(), but not with the extra space. Those functions are emitted as-is from the python script too...

I have access to a Mac OS X machine. The problem is not the output from Mako template but the "indent" command in Mac OS X (likely the same in FreeBSD) which is not the GNU one. That "indent" command is the responsible of adding those spaces.

I am going to do some tests and write a patch fixing it.

Thanks for your bug report!

Patch

I wrote a patch that fixes the issue for Mac OS X but I have not access to a FreeBSD machine.

Vinson, Can you apply the patch and tell me if it fixes the issue in FreeBSD too? Once you confirmed that, I will send it to the mailing list.

If you prefer to pull a branch, it is also available on top of today's master in my github repo:

https://github.com/samuelig/mesa/tree/fix-mac-os-x
