From 7446d35e1dd69e1da8241277eae09e293741b362 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Mon, 7 Sep 2015 10:39:28 +0100 Subject: target-arm/arm-semi.c: SYS_EXIT on A64 takes a parameter block The A64 semihosting API changes the interface for SYS_EXIT so that instead of taking a single exception type in a register, it takes a parameter block containing the exception type and a sub-code. Implement this.
