teak-llvm/clang/test/OpenMP/task_if_codegen.cpp
Alexey Bataev 2377fe95c6 [OPENMP] Outlined function for parallel and other regions with list of captured variables. 
Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least.
Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record.
