Reducing GLSL Compiler Memory Usage (or Fitting 5kg of Potatoes in a 2kg Bag)

Project: Mesa

Memory is cheap these days, but, alas, it is not free. In implementing the GLSL compiler in Mesa, we prioritized debugability and ease of implementation over other concerns. In late 2013 we discovered that some large applications would exhaust virtual address space on 32-bit architectures. Techniques and tools that were used to achieve significant improvements in memory usage. What do talloc, Valgrind, uniq, and Bloom filters have in common? Come find out.
