yes, but only for a few things.
Before changing it, ensure your gdb can deal with it. Normally that is
the cases
- On Mac, not sure as apple still distributes 6.3.50
- win 64 before fpc 2.6 , dwarf may not work
when choosing dwarf, always use "+ sets" (unless maybe again your gdb is
real old, I have used it with gdb 6.7.5 all ok)
dwarf 3 is experimental and works LESS well than dwarf (2) => unless you
have a specially patched gdb (archer branch).
(Though I did not test the archer gdb, no idea, if it is good)
----------------
biggest diff is
with dwarf you can inspect certain properties. that is ONLY properties
that directly map to a field.
Neither stabs, nor any dwarf will call a getter function.
stabs deals better with
- nested (dynamic) array
- param-by-ref "function foo( var RefParam: TBar)"
however Laz 0.9.31 deals with most of this.
there may be a few other diffs. I have no complete list
some fpc (or maybe the linker) had bugs, leaving out line info for parts
of try except. But I do not recall the exact details
