directives. 'kmp_task_t' record type added a new field for 'priority' clause and changed the representation of pointer to destructors for privates used within loop-based directives. Old representation: typedef struct kmp_task { /* GEH: Shouldn't this be aligned somehow? */ void *shareds; /**< pointer to block of pointers to shared vars */ kmp_routine_entry_t routine; /**< pointer to routine to call for executing task */ kmp_int32 part_id; /**< part id for the task */ kmp_routine_entry_t destructors; /* pointer to function to invoke deconstructors of firstprivate C++ objects */ /* private vars */ } kmp_task_t; New representation: typedef struct kmp_task { /* GEH: Shouldn't this be aligned somehow? */ void *shareds; /**< pointer to block of pointers to shared vars */ kmp_routine_entry_t routine; /**< pointer to routine to call for executing task */ kmp_int32 part_id; /**< part id for the task */ kmp_cmplrdata_t data1; /* Two known optional additions: destructors and priority */ kmp_cmplrdata_t data2; /* Process destructors first, priority second */ /* future data */ /* private vars */ } kmp_task_t; Also excessive initialization of 'destructors' fields to 'null' was removed from codegen if it is known that no destructors shal be used. Currently a special bit is used in 'kmp_tasking_flags_t' bitfields ('destructors_thunk' bitfield). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@271201 91177308-0d34-0410-b5e6-96231b3b80d8
