AFAICT, there is no real way to make sure a send message with EOT is properly ignored from compact, nor can I see a way to actually encode EOT while compacting. Before the single send optimization we'd always bail because we hit the is_immediate && !is_compactable_immediate case. However, with single send, is_immediate is not true, and so we end up trying to compact the un-compactible. Without this, any compacting single send instruction will hang because the EOT isn't there. I am not sure how I didn't hit this when I originally enabled the optimization. I didn't check if some surrounding code changed. I know Neil and Matt were both looking into this. I did a quick search and didn't see any patches out there to handle this. Please ignore if this has already been sent by someone. (Direct me to it and I will review it).

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 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.
