The pass I introduced in commit a2dc11a781
was entirely broken. A missing "break" made the load_interpolated_input
case always fall through to "default" and hit a "continue", making it
not actually move any load_interpolated_input intrinsics at all.
It would only move the simple load_barycentric_* intrinsics, which
don't emit any code anyway, making it basically useless.
The initial version I sent of the pass worked, but I apparently
failed to verify that the simplified version in v2 actually worked.
With the obvious fix applied (so we actually tried to move
load_interpolated_input intrinsics), I discovered a second bug: we
weren't moving the offset SSA def to the top, breaking SSA validation.
The new version of the pass actually moves load_interpolated_input
intrinsics and all their dependencies, as intended.
Papers over GPU hangs on Ivybridge and Baytrail caused by the
recent NIR FS input rework by restoring the old behavior.
(I'm not honestly sure why they hang with PLN not at the top.)

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.
