I count myself in that category as well. Assembler stepping is maybe
not for everyone, but if you want some fine grained control, you
sometimes need to delve deeper into the internals. This is
especially so with compiler-code or RTL speedups.
I've been trying to see if I could write a better/faster FillChar
last weekend.
a) as has been mentioned before, gdb does support assembler stepping
b) to step through FillChar's assembler code, you don't need assembler
stepping because the code was written in inline assembler. That means
that FPC generates Pascal-level debug information for each line of
assembler from that routine, and regular stepping will step through
that code one assembler statement at a time
While I get that gdb is a powerfull debugger (and cross-architecture/
platform), it too has a steep learning curve.
Maybe I should write a tutorial on the wiki, because there aren't that
many commands you have to know, along with a few gotchas. Time, time...
