OK to apply?
Seems to work on Linux. I'd sure like to see that backtrace test,
though, to confirm that we are able to build a meaningful machine
state after we attach.
Here is a new version of the patch, with the backtraces in. I do have
two FAILs though. The first FAIL comes from the following test:
gdb_test "backtrace" \
".*in nanosleep ().*in small_delay ().*in main ().*" \
"backtrace after attach2"
The logs show:
backtrace
#0 0x400eb3b5 in ?? () from /lib/libc.so.6
#1 0x08048412 in small_delay () at ./gdb.base/attach.c:18
#2 0x08048435 in main () at ./gdb.base/attach.c:29
(gdb) FAIL: gdb.base/attach.exp: backtrace after attach2
So the problem is that GDB is unable to find the function name for
frame $0. I think this comes from these warnings while performing
the attach command:
attach 3671
Attaching to process 3671

The second FAIL is identical.
