<p class="MsoNormal">These patches have more meat to them.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">two_task_teams.patch - The tt_state flag is removed and replaced by an array of two task_team pointers in the team struct. Each thread's local th_task_team points to one of those two task_teams on the team struct, and the thread's th_task_state
indicates which one. With this change, inside a barrier, the master thread can now change out the task_team on the team struct at any time, because the threads will switch to look at the other task_team. This gives us some flexibility in implementing barrier
algorithms that don’t have separate gather and release phases, like dissemination barriers.<span style="font-size:10.0pt;font-family:"Courier New""><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-autospace:none">backtrace_fix_cfi.patch - Inline assembly breaks back trace for OpenMP applications. This change adds CFI directives for stack tracing.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-autospace:none">omp_is_initial_device.patch - omp_is_initial_device() was implemented based on operating system:<o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none">We use _Offload_get_device_number() on Linux.
<o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none">And on other operating systems, omp_is_initial_device() always returns 1.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-autospace:none">debugger_struct_update.patch – updates the kmp_omp_struct_info_t for debuggers. Kmp_omp_struct_info_t is a structure that was prepared and exported as a static symbol<o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none">to be used for interfacing with debuggers. In this change, kmp_omp_struct_info_t structure was fixed to reflect the current OpenMP RTL structures.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">loop_out_of_bounds_fix.patch – small patch to fix a loop-out-of-bounds error for Fortran.<o:p></o:p></p>
