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. Signed-off-by: Jason Ekstrand <jason.ekstrand@intel.com> v2 by Samuel Iglesias <siglesias@igalia.com> - Remove format_pack.c as it is now autogenerated - Add usage of INDENT_FLAGS in Makefile.am - Remove trailing blank line v3 by Samuel Iglesias <siglesias@igalia.com> - Merge format_convert.py into format_parser.py - Adapt pack_*_* function generations - Fix out-of-tree build v4 by Samuel Iglesias <siglesias@igalia.com> - _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*() v7 by Samuel Iglesias <siglesias@igalia.com>: - Add assert to check that sRGB formats are 8-bit size. Signed-off-by: Samuel Iglesias Gonsalvez <siglesias@igalia.com> Reviewed-by: Jason Ekstrand <jason.ekstrand@intel.com>
