From: Gabe Black Date: Fri, 15 Feb 2019 16:00:20 +0000 (-0800) Subject: systemc: Export the tlm::tlm_global_quantum class to python. X-Git-Tag: v19.0.0.0~1096 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=055109800c5f65dcabd07c583c96a5fc20f86ce6;p=gem5.git systemc: Export the tlm::tlm_global_quantum class to python. This way the python code can set up the global quantum without having an sc_main function to do it.
