This patch makes the inferior command display information about the
current inferior when called with no argument. This behavior is similar
to the one of the thread command.
Before patch:
(gdb) info inferior
Num Description Connection Executable
* 1 process 19221 1 (native) /home/lsix/tmp/a.out
2 process 19239 1 (native) /home/lsix/tmp/a.out
(gdb) inferior 2
[Switching to inferior 2 [process 19239] (/home/lsix/tmp/a.out)]
[Switching to thread 2.1 (process 19239)]
#0 0x0000000000401146 in main ()
(gdb) inferior
Argument required (expression to compute).
After patch:
(gdb) info inferior
Num Description Connection Executable
* 1 process 18699 1 (native) /home/lsix/tmp/a.out
2 process 18705 1 (native) /home/lsix/tmp/a.out
(gdb) inferior 2
[Switching to inferior 2 [process 18705] (/home/lsix/tmp/a.out)]
[Switching to thread 2.1 (process 18705)]
#0 0x0000000000401146 in main ()
(gdb) inferior
[Current inferior is 2 [process 18705] (/home/lsix/tmp/a.out)]
gdb/doc/ChangeLog:
* gdb.texinfo (Inferiors Connections and Programs): Document the
inferior command when used without argument.
gdb/ChangeLog:
* NEWS: Add entry for the behavior change of the inferior command.
* inferior.c (inferior_command): When no argument is given to the
inferior command, display info about the currently selected
inferior.
gdb/testsuite/ChangeLog:
* gdb.base/inferior-noarg.c: New test.
* gdb.base/inferior-noarg.exp: New test.
