clang-p2996/clang/test/OpenMP/nvptx_target_printf_codegen.c
Johannes Doerfert b8cbc5c02c [OpenMP] Introduce the KernelLaunchEnvironment as implicit argument (#70401) 
The KernelEnvironment is for compile time information about a kernel. It
allows the compiler to feed information to the runtime. The
KernelLaunchEnvironment is for dynamic information *per* kernel launch.
It allows the rutime to feed information to the kernel that is not
shared with other invocations of the kernel. The first use case is to
replace the globals that synchronize teams reductions with per-launch
versions. This allows concurrent teams reductions. More uses cases will
follow, e.g., per launch memory pools.
