Hi，ahoeller：
I imitate your arm architecture to implement PowerPC fault injection.I made changes to register in fault injection module (regs of arm to gpr of powerpc,delete cpsr) and In target-ppc/translate.c ,fault_injection_controller_init function was called (gen_intermediate_code_internal).Mainly changed these.but,when i finished make it and run it like arm:ppc-softmmu/qemu-system-ppc -kernel hello, the terminal keeping printing:

• softmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d84softmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8csoftmmu-header3: 7df7d88softmmu-header3: 7df7d8c

qemu display：

• Welcome to Openbios v1.1 built on ........

I'm not sure the error is caused by me or the qemu itself,but I am more inclined to qemu caused .
any help will be grateful !

I'm compiling the project FIES you posted on github. But I fall through a probelm when the build program come to this step "LINK arm-softmmu/qemu-system-arm", it report some error like:

fault-injection-library.o: In function qmp_fault_reload': /home/yan/Documents/fies-master/fault-injection-library.c:621: undefined reference to xmlCheckVersion'

There are many more below, but they are similar to the one above.
I use the ubuntu 14.04, and I can confirm that my libxml2 is installed properly. So I don't know what went wrong.
I would be very grateful if you can give me some help.

Running Ubuntu 16.04
install libs:

sudo apt install libffi6 libffi-dev libc6-dev gettext python pkg-config libsdl2-dev zlib1g-dev libpixman-1-dev libfdt-dev libxml2-dev
sudo apt install libsdl1.2debian libsdl-gfx1.2-5 libsdl-gfx1.2-dev libsdl-gfx1.2-doc libsdl-image1.2 libsdl-image1.2-dbg libsdl-image1.2-dev libsdl-mixer1.2 libsdl-mixer1.2-dbg libsdl-mixer1.2-dev libsdl-net1.2 libsdl-net1.2-dbg libsdl-net1.2-dev libsdl-sound1.2 libsdl-sound1.2-dev libsdl-ttf2.0-0 libsdl-ttf2.0-dev

Had to add --disable-werror for ./configure for couple of noisy warnings e.g.
warning: ‘g_mem_set_vtable’ is deprecated [-Wdeprecated-declarations]

link error from libxml2:

LINK  arm-softmmu/qemu-system-arm
fault-injection-library.o: In function `qmp_fault_reload':
/ws/open-source/fies/fault-injection-library.c:621: undefined reference to `xmlCheckVersion'

I am not able to change instruction at specific address (0x000082a8) by new instruction (code: 0xe3530000). Here is my injection XML file:

<?xml version="1.0" encoding="UTF-8"?>
<injection>
	<fault>
		<id>1</id>
		<component>CPU</component>
		<target>INSTRUCTION EXECUTION</target>
		<mode>NEW VALUE</mode>
		<trigger>PC</trigger>
		<params> 
			<address>0x000082a8</address>
			<instruction>0xe3530000</instruction>
		</params>
	</fault>
</injection>

If I understand PC trigger correctly, address param is pointer to the instruction location (injection will be triggered when program counter points to this address) and instruciton is instruction which will be placed on that code address. Unfortunatelly, I cant get it work. I checked that func do_inject_look_up_error_arm (file fault-injection-injector.c) is called with correct lockup_instruction, but value in env->regs[15] did not change at all.
