From 205ace55ffff77964e50af08c99639ec47db53f6 Mon Sep 17 00:00:00 2001 From: Christopher Covington Date: Mon, 7 Sep 2015 10:39:27 +0100 Subject: target-arm: Improve semihosting debug prints Print semihosting debugging information before the do_arm_semihosting() call so that angel_SWIreason_ReportException, which causes the function to not return, gets the same debug prints as other semihosting calls. Also print out the semihosting call number.
