[OPENMP] Codegen for 'copyin' clause in 'parallel' directive. Emits the following code for the clause at the beginning of the outlined function for implicit threads: if (<not a master thread>) { ... <thread local copy of var> = <master thread local copy of var>; ... } <sync point>; Checking for a non-master thread is performed by comparing of the address of the thread local variable with the address of the master's variable. Master thread always uses original variables, so you always know the address of the variable in the master thread. Differential Revision: http://reviews.llvm.org/D9026 llvm-svn: 235075

[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. llvm-svn: 247251

If the OpenMP region does not have internal 'cancel' construct, a call to 'void __kmpc_barrier()' runtime function is generated for all implicit/explicit barriers. If the region has inner 'cancel' directive, then ``` if (__kmpc_cancel_barrier()) exit from outer construct; ``` code is generated.

[OPENMP] Codegen for 'copyin' clause in 'parallel' directive. Emits the following code for the clause at the beginning of the outlined function for implicit threads: if (<not a master thread>) { ... <thread local copy of var> = <master thread local copy of var>; ... } <sync point>; Checking for a non-master thread is performed by comparing of the address of the thread local variable with the address of the master's variable.

[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. llvm-svn: 247251
