Committed. Thanks, - Tom
[nvptx] Use TARGET_SET_CURRENT_FUNCTION Implement TARGET_SET_CURRENT_FUNCTION for nvptx. This gives us a place to add initialization or reset actions that need to be executed on a per-function basis. Build and reg-tested on x86_64 with nvptx accelerator. 2018-12-17 Tom de Vries <tdevr...@suse.de> * config/nvptx/nvptx.c (nvptx_previous_fndecl): Declare. (nvptx_set_current_function): New function.
