[OPENMP] Codegen for 'if' clause in 'parallel' directive. Adds codegen for 'if' clause. Currently only for 'if' clause used with the 'parallel' directive. If condition evaluates to true, the code executes parallel version of the code by calling __kmpc_fork_call(loc, 1, microtask, captured_struct/*context*/), where loc - debug location, 1 - number of additional parameters after "microtask" argument, microtask - is outlined finction for the code associated with the 'parallel' directive, captured_struct - list of variables captured in this outlined function. If condition evaluates to false, the code executes serial version of the code by executing the following code: global_thread_id.addr = alloca i32 store i32 global_thread_id, global_thread_id.addr zero.addr = alloca i32 store i32 0, zero.addr kmpc_serialized_parallel(loc, global_thread_id); microtask(global_thread_id.addr, zero.addr, captured_struct/*context*/); kmpc_end_serialized_parallel(loc, global_thread_id); Where loc - debug location, global_thread_id - global thread id, returned by __kmpc_global_thread_num() call or passed as a first parameter in microtask() call, global_thread_id.addr - address of the variable, where stored global_thread_id value, zero.addr - implicit bound thread id (should be set to 0 for serial call), microtask() and captured_struct are the same as in parallel call. Also this patch checks if the condition is constant and if it is constant it evaluates its value and then generates either parallel version of the code (if the condition evaluates to true), or the serial version of the code (if the condition evaluates to false).

[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

[OPENMP] Codegen for 'if' clause in 'parallel' directive. Adds codegen for 'if' clause. Currently only for 'if' clause used with the 'parallel' directive. If condition evaluates to true, the code executes parallel version of the code by calling __kmpc_fork_call(loc, 1, microtask, captured_struct/*context*/), where loc - debug location, 1 - number of additional parameters after "microtask" argument, microtask - is outlined finction for the code associated with the 'parallel' directive, captured_struct - list of variables captured in this outlined function. If condition evaluates to false, the code executes serial version of the code by executing the following code: global_thread_id.addr = alloca i32 store i32 global_thread_id, global_thread_id.addr zero.addr = alloca i32 store i32 0, zero.addr kmpc_serialized_parallel(loc, global_thread_id); microtask(global_thread_id.addr, zero.addr, captured_struct/*context*/); kmpc_end_serialized_parallel(loc, global_thread_id); Where loc - debug location, global_thread_id - global thread id, returned by __kmpc_global_thread_num() call or passed as a first parameter in microtask() call, global_thread_id.addr - address of the variable, where stored global_thread_id value, zero.addr - implicit bound thread id (should be set to 0 for serial call), microtask() and captured_struct are the same as in parallel call. Also this patch checks if the condition is constant and if it is constant it evaluates its value and then generates either parallel version of the code (if the condition evaluates to true), or the serial version of the code (if the condition evaluates to false).

[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.

[OPENMP] Codegen for 'if' clause in 'parallel' directive. Adds codegen for 'if' clause. Currently only for 'if' clause used with the 'parallel' directive. If condition evaluates to true, the code executes parallel version of the code by calling __kmpc_fork_call(loc, 1, microtask, captured_struct/*context*/), where loc - debug location, 1 - number of additional parameters after "microtask" argument, microtask - is outlined finction for the code associated with the 'parallel' directive, captured_struct - list of variables captured in this outlined function. If condition evaluates to false, the code executes serial version of the code by executing the following code: global_thread_id.addr = alloca i32 store i32 global_thread_id, global_thread_id.addr zero.addr = alloca i32 store i32 0, zero.addr kmpc_serialized_parallel(loc, global_thread_id); microtask(global_thread_id.addr, zero.addr, captured_struct/*context*/); kmpc_end_serialized_parallel(loc, global_thread_id); Where loc - debug location, global_thread_id - global thread id, returned by __kmpc_global_thread_num() call or passed as a first parameter in microtask() call, global_thread_id.addr - address of the variable, where stored global_thread_id value, zero.addr - implicit bound thread id (should be set to 0 for serial call), microtask() and captured_struct are the same as in parallel call. Also this patch checks if the condition is constant and if it is constant it evaluates its value and then generates either parallel version of the code (if the condition evaluates to true), or the serial version of the code (if the condition evaluates to false).

// CHECK: ret void
Account for calling convention specifiers in function definitions in IR test cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971
