With -O0 opt level, gdb refuses to step (S) over a delay loop like this:
code1; //<-- steps over this OK for(c=0; c<10000; c++); //<--- hangs here code2; If I control-c and examine c it seems to be increasing slowly. When I change the code structure like this: code1; for(c=0; c<10000; ) c++; code2; then I can step.This is with embedded arm. See the same thing with arm-insight and arm-gdb. Haven't tried this with native.
Is this to be expected?
