If we're in some conditional or loop we must not return, or the code after the condition is never executed. (v2): And, we also can't just continue as nothing happened, since the mask update code would later check if we actually have a mask, so we need to remember that there was a return in main where we didn't exit (to illustrate this, a ret in a if clause would cause a mask update which is still ok as we're in a conditional, but after the endif the mask update code would drop the mask hence bringing execution back to pixels which should have their execution mask set to zero by the ret). Thanks to Christoph Bumiller for figuring this out. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=62357. Note: This is a candidate for the stable branches.

File: docs/README.WIN32 Last updated: 23 April 2011 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. 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.
