[RFA] ARI fix: %p rule
- From: "Pierre Muller" <muller at ics dot u-strasbg dot fr>
- To: <gdb-patches at sourceware dot org>
- Date: Fri, 17 Apr 2009 08:32:43 +0200
- Subject: [RFA] ARI fix: %p rule
Most of the remaining usages of %p
in printf family messages
are related to pointers in the host space
rater that target space.
Thus the recommendation to use paddress
is not correct for these cases, and I
used host_address_to_string instead.
Is this OK?
Pierre Muller
Pascal language support maintainer for GDB
I left a few cases out, where
the %p value was not a simple pointer
but a arithmetic operation,
I don't know the rules for C,
is an addition of a pointer and a integer
always of type pointer?
2009-04-17 Pierre Muller <muller.u-strasbg.fr>
ARI fix: Do not use %p, replace by call to host_address_to_string
for host pointers.
