From b1311c4acf503dc9c1a310cc40b64f05b08833dc Mon Sep 17 00:00:00 2001 From: "Emilio G. Cota" Date: Wed, 12 Jul 2017 17:15:52 -0400 Subject: tcg: define tcg_init_ctx and make tcg_ctx a pointer Groundwork for supporting multiple TCG contexts. The core of this patch is this change to tcg/tcg.h: > -extern TCGContext tcg_ctx; > +extern TCGContext tcg_init_ctx; > +extern TCGContext *tcg_ctx; Note that for now we set *tcg_ctx to whatever TCGContext is passed to tcg_context_init -- in this case &tcg_init_ctx.
