From af0484b5025f8b7c951428a00b5bb3f172a2da8d Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 28 Apr 2022 11:40:41 -0700 Subject: semihosting: Split out semihost_sys_read Split out the non-ARM specific portions of SYS_READ to a reusable function. This handles all GuestFD. Isolate the curious ARM-specific return value processing to a new callback, common_semi_rw_cb. Note that gdb_do_syscall %x reads target_ulong, not int.
