This is the next in the new-style debug macro series.
For this one, I decided to omit the function name from the "Sending packet" /
"Packet received" kind of prints, just because it's not very useful in that
context and hinders readability more than anything else. This is completely
arbitrary.
This is with:
[remote] putpkt_binary: Sending packet: $qTStatus#49...
[remote] getpkt_or_notif_sane_1: Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
and without:
[remote] Sending packet: $qTStatus#49...
[remote] Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
A difference is that previously, the query packet and its reply would be
printed on the same line, like this:
Sending packet: $qTStatus#49...Packet received: T0;tnotrun:0;tframes:0;tcreated:0;tfree:500000;tsize:500000;circular:0;disconn:0;starttime:0;stoptime:0;username:;notes::
Now, they are printed on two lines, since each remote_debug_printf{,_nofunc}
prints its own complete message including an end of line. It's probably
a matter of taste, but I prefer the two-line version, it's easier to
follow, especially when the query packet is long.
As a result, lib/range-stepping-support.exp needs to be updated, as it
currently expects the vCont packet and the reply to be on the same line.
I think it's sufficient in that context to just expect the vCont packet
and not the reply, since the goal is just to count how many vCont;r GDB
sends.
gdb/ChangeLog:
* remote.h (remote_debug_printf): New.
(remote_debug_printf_nofunc): New.
(REMOTE_SCOPED_DEBUG_ENTER_EXIT): New.
* remote.c: Use above macros throughout file.
gdbsupport/ChangeLog:
* common-debug.h (debug_prefixed_printf_cond_nofunc): New.
* common-debug.c (debug_prefixed_vprintf): Handle a nullptr
func.
gdb/testsuite/ChangeLog:
* lib/range-stepping-support.exp (exec_cmd_expect_vCont_count):
Adjust to "set debug remote" changes.
