From 63fd5b5ddad9c715531168d5863853017a1f02d3 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 12 Nov 2022 01:15:32 +0700 Subject: sim: switch sim_{read,write} APIs to 64-bit all the time [PR sim/7504] We've been using SIM_ADDR which has always been 32-bit. This means the upper 32-bit address range in 64-bit sims is inaccessible. Use 64-bit addresses all the time since we want the APIs to be stable regardless of the active arch backend (which can be 32 or 64-bit). The length is also 64-bit because it's completely feasible to have a program that is larger than 4 GiB in size/image/runtime. Forcing the caller to manually chunk those accesses up into 4 GiB at a time doesn't seem useful to anyone.
