That's the problem, the name "backtrace" itself is already a bit confusing.

It is a "backtrace" into history, not into upper frames.
	(gdb) record backtrace 
	_IO_vsnprintf
	_IO_vfprintf_internal
	strchrnul
	_IO_vfprintf_internal
	__GI__IO_default_xsputn
You can see _IO_vfprintf_internal called strchrnul which then returned back to
_IO_vfprintf_internal.  This is not a real "backtrace".

I was already considering renaming the command as the term is a bit overloaded
in the debugger context.

Maybe "record list-functions"?  It is also very similar to the "record list"
command there which lists lines:
      (gdb) btrace list 24-34
      24     in stdio_file_flush () at ../../../git/gdb/ui-file.c:525-529
      25     in ui_file_data () at ../../../git/gdb/ui-file.c:175-180
      26     in stdio_file_flush () at ../../../git/gdb/ui-file.c:522-523
      27     in gdb_flush () at ../../../git/gdb/ui-file.c:185

While I understand "record list" was trying to match the existing "list"
command I do not find it too intuitive, so maybe "record list-lines"?


Thanks,
