Roland Scheidegger 74f505fa73 gallivm: fix alignment issue for vertex data fetch
We cannot guarantee that vertex buffers have the necessary alignment for
fetching all AoS members at once (for instance 4x32bit XYZW data). We can
however guarantee that for textures. This did not cause errors for older
llvm versions but it now matters and will cause segfaults if the data
happens to not be aligned. Thus we need to set alignment manually.
(Note that we can't actually really guarantee data to be even element aligned
due to offsets in vertex buffers being bytes and OpenGL allowing this, but
it does not matter for x86 as alignment is only required for sse vectors -
not sure what happens on other archs, however.)

This fixes https://bugs.freedesktop.org/show_bug.cgi?id=85467.

File: docs/README.WIN32

Last updated: 21 June 2013


Quick Start
----- -----

Windows drivers are build with SCons.  Makefiles or Visual Studio projects are
no longer shipped or supported.

Run

  scons osmesa mesagdi

to build classic mesa Windows GDI drivers; or

  scons libgl-gdi

to build gallium based GDI driver.

This will work both with MSVS or Mingw.


Windows Drivers
------- -------

At this time, only the gallium GDI driver is known to work.

Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.

Recipe
------

Building on windows requires several open-source packages. These are
steps that work as of this writing.

- install python 2.7
- install scons (latest)
- install mingw, flex, and bison
- install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs
  get pywin32-218.4.win-amd64-py2.7.exe
- install git
- download mesa from git
  see http://www.mesa3d.org/repository.html
- run scons

General
-------

After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
in a system directory, place them in the same directory as the
executable(s).  Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.

The DLL files are built so that the external entry points use the
stdcall calling convention.

Static LIB files are not built.  The LIB files that are built with are
the linker import files associated with the DLL files.

The si-glu sources are used to build the GLU libs.  This was done
mainly to get the better tessellator code.

If you have a Windows-related build problem or question, please post
to the mesa-dev or mesa-users list.
