PR 17539 points out that "info inferiors" lists inferiors in
decreasing order. I audited the "info" sub commands, and GDB is
inconsistent on this issue in several places. Some commands list in
ascending order, while others in descending order.
For example, ascending order:
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x00000000004008ad in main at foo.c:81
2 breakpoint keep y 0x00000000004008ad in main at foo.c:81
3 breakpoint keep y 0x00000000004008ad in main at foo.c:81
4 breakpoint keep y 0x00000000004008ad in main at foo.c:81
(gdb)
(gdb) info skip
Num Type Enb What
1 function y main
2 function y main
3 function y main
(gdb)
(gdb) info bookmarks
1 0x4008ad '0'
2 0x4008ad '0'
3 0x4008ad '0'
4 0x4008ad '0'
(gdb)
(gdb) info tasks
ID TID P-ID Pri State Name
1 8088000 0 15 Child Activation Wait main_task
2 80a4000 1 15 Accept Statement b
3 809a800 1 15 Child Activation Wait a
* 4 80ae800 3 15 Runnable c
(gdb)
Descending:
(gdb) info display
Auto-display expressions now in effect:
Num Enb Expression
4: y 1
3: y 1
2: y 1
1: y 1
(gdb)
(gdb) info threads
Id Target Id Frame
3 Thread 0x7ffff77c3700 (LWP 29035) callme () at foo.c:30
2 Thread 0x7ffff7fc4700 (LWP 29034) function (arg=0x0) at foo.c:60
* 1 Thread 0x7ffff7fc5740 (LWP 29030) main () at foo.c:92
(gdb)
(gdb) info inferiors

This patch series switches all "descending order" commands I found to
ascending order, and adjusts manual and testsuite accordingly.
Pedro Alves (6):
Make gdb.python/py-inferior.exp test names unique
Linux: dump the signalled thread first
List inferiors/threads/pspaces in ascending order
List checkpoints in ascending order
List displays in ascending order
NEWS: "info" commands now list in ascending order
