They are OK, but:
. The doc strings use too long lines, which will look ugly on your
garden-variety 80-column terminal.
. In the gdb.texinfo, don't put "set" and "show" commands in the
same @item/@itemx, because the text below them says "Control
whether...", which is inappropriate for the "show" command.
. "Displaced stepping" is really a bad name for this feature. Is it
widely accepted or did we invent it?
. This text:
+@cindex non-stop mode, and @samp{set can-use-displaced-stepping}
+@item set can-use-displaced-stepping auto
+This is the default mode. @value{GDBN} will use displaced stepping
+only if non-stop mode is active (@pxref{Non-Stop Mode}) and the target
+architecture supports it.
needs to be rephrased in the last sentence, to disambiguate the
"supports it" part: a reader could be confused to think that "it"
refers to the non-stop mode, not to displaced stepping.
. Why isn't it better to use displaced stepping, if supported, even
if non-stop mode is not in effect? I think the linkage between
the two is confusing and unnecessary.
. I agree with Daniel's criticism of the can-use-displaced-stepping
option's name. An obvious first step towards making it shorter
would be to remove the "can-" prefix.
Thanks.
