From e1fee58fea3a8d215029269235d82cf6f79c1749 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Tue, 19 Sep 2023 16:25:54 +0200 Subject: [PATCH] include/hw/elf: Remove truncating signed casts There's nothing about elf that specifically requires signed vs unsigned. This is very much a target-specific preference. In the meantime, casting low and high from uint64_t back to Elf_SWord to uint64_t discards high bits that might have been set by translate_fn.
