[Qemu-devel] [PATCH 1/3] arm: semihosting: Improve debug prints |
Date: |
Fri, 27 Mar 2015 12:22:33 -0400 |
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.
