From 1d41478fd428e01f057d3248292e4cdcdb048523 Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Thu, 12 May 2016 13:22:26 +0100 Subject: [PATCH] tcg: Add tcg_set_insn_param Add tcg_set_insn_param as a mechanism to modify an insn parameter after emiting the insn. This is useful for icount and also for embedding fault information for a specific insn. Reviewed-by: Richard Henderson Signed-off-by: Edgar E.
