Re: [U-Boot] compiled failed when turned off gcc optimazition

Dear Mike Dunn,

But there's a good motivation for wanting to turn off optimization.

I disagree here. If you are hunting down a problem, you want to be as close at the original code as possible. Disabling optimization is such a dramatic change to the generated code that you actually debug a different program.

Single-stepping with a debugger at the C source level is almost useless. I've since gotten better at single-stepping at the assembly level while using the mixed c and assembly view of gdb.

Hm... Did you read up the documentation, say [1], and try out these recommendations?
