Hello,

I'm getting acquainted with QEMU's internals because I'll need to know them
very well for the next few months. I've reached a point where I want to
debug QEMU with gdb in order to better understand the code flux related to
some things that are still not clear after just looking at the code.

The thing is, debugging QEMU with GDB seems to be quite troublesome. GDB
keeps reporting the wrong source-code location when stepping through the
code and I'm unable to insert breakpoints at some of the most important
functions. I've tried to disable GCC optimizations, but the compilation
fails without -O2.

Is this my fault? How can I fix it?

Or, is this the expected behavior? In that case, which techniques do you use
to debug QEMU?

Thanks in advance,

Luís Pureza
