This pull request is a revised version of #76587. This pull request fixes some build issues that were present in the previous version of this change. > This pull request is the first part of an ongoing effort to extends PGO instrumentation to GPU device code. This PR makes the following changes: > > - Adds blank registration functions to device RTL > - Gives PGO globals protected visibility when targeting a supported GPU > - Handles any addrspace casts for PGO calls > - Implements PGO global extraction in GPU plugins (currently only dumps info) > > These changes can be tested by supplying `-fprofile-instrument=clang` while targeting a GPU.
