...he intrinsics to the specific libgomp or mpc library calls. If already possible at compile time, fast LLVM-IR sequences can be inlined instead of calling actual library functions. pragma omp for schedule(runtime) for ( i=lb ; i COND b ; i+=incr ) { A ; } -> Represented as LLVM-IR def original_function() { llvm.openmp.loop(lower_bound, upper_bound, body, context, schedule) } def body(i, context) { A(i); } -> Lowering to MPC: (for schedule = runtime) if ( __mpcomp_runtime_loop_begin( ... ) ) { do { for ( ... ) { A ; } } while ( __mpcomp_runtime_lo...

I am interested. I would be grateful for your hints. So OpenMP has various constructs such as parallel, barrier, single, for, etc. And there is at least two libraries to generate OpenMP code: libgomp and mpc. We want to be independent of specific library. We should create an interface with methods which present manual inserting of OpenMP pragmas in C or Fortran code. These sounds like "this

...ructs will be very important for some platforms. We may need some new attributes in the IR so that we can still safely do things like LICM. -Hal > > pragma omp for schedule(runtime) > for ( i=lb ; i COND b ; i+=incr ) { A ; } > > -> Represented as LLVM-IR > > def original_function() { > llvm.openmp.loop(lower_bound, upper_bound, body, context, schedule) > } > > def body(i, context) { > A(i); > } > > -> Lowering to MPC: (for schedule = runtime) > > if ( __mpcomp_runtime_loop_begin( ... ) ) { > do { > for ( ....
