As for cfldrdeq, I believe it's just a conditional cfldrd instruction (the "eq" is a condition code), which Google suggests is related to a the Cirrus Logic "Maverick" processor series.

bar: int pointer_to_the_actual_syscall I do not know why the disassembly for syscall() places "foo" between ldr r12,[pc,r12] and bx r12, causing the branch over the non-instruction "foo". I added this code to my C program using asm().

Contradictionary to the limits you mention, multiple suspend/resume cycles do work for me. Can someone please explain what instructions at offsets +28,+32 are doing?
