I found where my confusion was coming from, but I would like clarification that omp_get_proc_bind is doing the right thing:
<div class=""><br class="">
</div>
<div class="">At line 5473 in kmp_settings.cpp</div>
<div class=""><br class="">
</div>
<div class="">
<div class=""> } else if (__kmp_nested_proc_bind.bind_types[0] == proc_bind_true) {</div>
<div class=""> // OMP_PROC_BIND=true maps to OMP_PROC_BIND=spread.</div>
<div class=""> __kmp_nested_proc_bind.bind_types[0] = proc_bind_spread;</div>
<div class=""> }</div>
<div class=""><br class="">
</div>
<div class="">Even if libomp uses spread internally for the case of OMP_PROC_BIND=true shouldn’t omp_get_proc_bind still report that the value true was provided instead of the value for spread? </div>

I am writing to figure out what is the expected result from get_omp_proc_bind when the environmental variable OMP_PROC_BIND is true. Based on <a href="https://www.openmp.org/spec-html/5.0/openmpse52.html" class="">https://www.openmp.org/spec-html/5.0/openmpse52.html</a> I
was expecting the result to be 1, which is what I get when using g++ version 9.2, but for clang++ I get 4, which is the same as spread. Any help would be appreciated since I am trying to match up results from an app compiled with clang and a performance model
that currently returns 1 for get_omp_proc_bind when OMP_PROC_BIND=true.
