/* This file is unusual.
|
|
|
|
Because both libiberty and readline define xmalloc and friends, the
|
|
functions in this file can't appear in a library -- that will cause
|
|
link errors.
|
|
|
|
And, because we want to turn the common code into a library, this
|
|
file can't live there.
|
|
|
|
So, it lives in gdb and is built separately by gdb and gdbserver.
|
|
Please be aware of this when modifying it.
|
|
|
|
This also explains why this file includes common-defs.h and not
|
|
defs.h or server.h -- we'd prefer to avoid depending on the
|
|
GDBSERVER define when possible, and for this file it seemed
|
|
simple to do so. */
