[RFC]: Info tracepoint, allow for 64 bit addresses
- To: gdb-patches at sources dot redhat dot com
- Subject: [RFC]: Info tracepoint, allow for 64 bit addresses
- From: Michael Snyder <msnyder at cygnus dot com>
- Date: Thu, 15 Mar 2001 15:15:45 -0800
- Organization: Red Hat
This change parallels yesterdays change to breakpoint.c.
This one required a few testsuite tweaks. If I don't hear
objections, I will check both in on Monday.
2001-03-14 Michael Snyder <msnyder@redhat.com>
* tracepoint.c (tracepoints_info): Handle 64-bit addresses.
* testsuite/gdb.trace/deltrace.exp: Allow for 64-bit addresses.
* testsuite/gdb.trace/infotrace.exp: Ditto.
* testsuite/gdb.trace/passcount.exp: Ditto.
* testsuite/gdb.trace/while-stepping.exp: Ditto.
