*** Changes since GDB 5.3:
|
||||
|
||||
* Profiling support
|
||||
|
||||
A new command, "maint set profile on/off", has been added. This command can
|
||||
be used to enable or disable profiling while running GDB, to profile a
|
||||
session or a set of commands. In addition there is a new configure switch,
|
||||
"--enable-profiling", which will cause GDB to be compiled with profiling
|
||||
data, for more informative profiling results.
|
||||
|
||||
* Default MI syntax changed to "mi2".
|
||||
|
||||
The default MI (machine interface) syntax, enabled by the command line
