Hope that helps
I've noticed that when I step over or into in the debugger, it comes to the last line of a specific timer ISR.

Understanding disassembly of Dalvik code?

will be helpful for those in need What you're looking at is the davlik bytecode. Java code is translated to Dalvik bytecode by the dx tool. The manifest is a separate issue which I'll get to in a minute. Effectively, when you compile your Android application, the dx tool converts your Java code into bytecode (the same way that javac converts Java to Java bytecode for a standard JVM application) using the 256 dalvik opcodes.
For example, invoke-super is an opcode that instructs the dvm (dalvik virtual machine) to invoke a method on the super class. Similarly, invoke-interface instructs the dvm to invoke an interface method.
code :
invoke-super {p0, p1}, Landroid/app/Activity;->onCreate(Landroid/os/Bundle;)
invoke-direct {p0}, Landroid/app/Activity;-><init>()V

seems to work fine I've found this document and this document describing the assembly language, that explains some of the mnemonics you have found in the assembly.
At this level, the assembly is very specific to the hardware; since you have used AMD tools, I thought to look for AMD devices documents. I won't be surprised if NVIDIA uses a different instruction set.

it fixes the issue In ObjC there are two implicit parameters to every method, self and _cmd. These are passed in %rdi and %rsi (that's the rules of the 64-bit ABI). They're being saved to the stack in case we overwrite those registers with another function call somewhere in this method. If you turn on optimizations, you'll see that those instructions are removed (since we never actually need the saved values).

should help you out You are not seeing two main()s. You are seeing a disassembler utterly confused out of its mind by a for loop. The actual assembly, if you read it all the way through, represents exactly one function, main(), and the logic path is identical to the C code.
In short: the C interleaved into the assembly is wrong.
