From 7625a1ed013a042748753750c9d9b1a33c9cd8e0 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Sun, 14 Mar 2021 16:49:30 -0600 Subject: utils: Use fixed-point arithmetic in qemu_strtosz Once we've parsed the fractional value, extract it into an integral 64-bit fraction. Perform the scaling with integer arithmetic, and simplify the overflow detection.
