So far indirect addressing was not tracked to estimate the temporary
life time, and it was not needed, because code to load the address
registers was always emitted eliminating the reladdr* handles in the
past glsl-to.tgsi stages. Now, with Mareks patch allowing any 1D register
to be used for addressing on some hardware this changed, and
the tracking becomes necessary.
Because the registers have no direct indication on whether the reladdr* was
already loaded into an address register, the temporaries in reladdr* are
always tracked as reads. This may result in a slight over-estimation of the
lifetime in the cases when the load to the address register was emitted.
v2: no changes
v3: Use debug_log variable instead of directly writing to std::err in debugging
output.
v6: fix indention and typos

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 https://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.
