And another try for constant folding of Instructions for nvc0. Please Review this! Thanks, Tobias Klausmann Tobias Klausmann (4): nvc0/ir: clear subop when folding constant expressions nvc0/ir: Handle reverse subop for OP_EXTBF when folding constant expressions nvc0/ir: Handle OP_BFIND when folding constant expressions nvc0/ir: Handle OP_POPCNT when folding constant expressions

Hello there, This series exposes NVIDIA's global performance counters for Tesla through the Gallium's HUD and the GL_AMD_performance_monitor extension. This adds support for 24 hardware events which have been reverse engineered with PerfKit (Windows) and CUPTI (Linux). These hardware events will allow developers to profile OpenGL applications. To reduce latency and to improve accuracy,
