From df2cce2968069526553d82331ce9817eaca6b03a Mon Sep 17 00:00:00 2001 From: "Emilio G. Cota" Date: Wed, 12 Jul 2017 18:26:40 -0400 Subject: [PATCH] tcg: introduce **tcg_ctxs to keep track of all TCGContext's Groundwork for supporting multiple TCG contexts. Note that having n_tcg_ctxs is unnecessary. However, it is convenient to have it, since it will simplify iterating over the array: we'll have just a for loop instead of having to iterate over a NULL-terminated array (which would require n+1 elems) or having to check with ifdef's for usermode/softmmu.
