Not something actually hit in real life (now state is never non-null,
but only case state->syms is null is if nir_print_instr() path). But it
was something I overlooked the first time, so might as well fix it.
*** CID 1324642: Null pointer dereferences (REVERSE_INULL)
/src/glsl/nir/nir_print.c: 299 in print_var_decl()

294 fprintf(fp, " (%s, %u)", loc, var->data.driver_location);
295 }
296
297 fprintf(fp, "\n");

>>> CID 1324642: Null pointer dereferences (REVERSE_INULL)
>>> Null-checking "state" suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
299 if (state) {
300 _mesa_set_add(state->syms, name);
301 _mesa_hash_table_insert(state->ht, var, name);

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.
