Even if the target supports this, if the target's file copy is stripped, which it usually is, you'll still need to manually pass the unstripped program to gdb. I think we should rephrase it a bit making sure that is clear. Maybe something like this? : -On the @value{GDBN} host machine, you will need an unstripped copy of -your program, since @value{GDBN} needs symbol and debugging information. -Start up @value{GDBN} as usual, using the name of the local copy of your -program as the first argument. +@value{GDBN} needs an unstripped copy of your program to access symbol +and debugging information. Some remote targets@footnote{@xref{qXfer +executable filename read}, and @ref{Host I/O Packets}.} allow +@value{GDBN} to access program files over the same connection used to +communicate with @value{GDBN}. With such a target, unless the remote +program file is stripped, the only command you need is +@code{target remote}. Otherwise, start up @value{GDBN} using the +name of the local unstripped copy of your program as the first +argument, or use the @code{file} command. Thanks, Pedro Alves
