* [Bug breakpoints/15697] New: Unnecessary =breakpoint-modified event when hitting dprintf @ 2013-06-27 20:31 marc.khouzam at ericsson dot com 2014-01-10 16:24 ` [Bug breakpoints/15697] " marc.khouzam at ericsson dot com ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: marc.khouzam at ericsson dot com @ 2013-06-27 20:31 UTC (permalink / raw) To: gdb-prs http://sourceware.org/bugzilla/show_bug.cgi?id=15697 Bug ID: 15697 Summary: Unnecessary =breakpoint-modified event when hitting dprintf Product: gdb Version: HEAD Status: NEW Severity: normal Priority: P2 Component: breakpoints Assignee: unassigned at sourceware dot org Reporter: marc.khouzam at ericsson dot com I believe there was an agreement that it was not a good idea to send a =breakpoint-modified event each time a dprintf was hit. When a dprintf is in a loop, these event can become quite inefficient. Furthermore, these events are not sent when using 'agent' dprintf-style. Please see discussion and agreement here: http://sourceware.org/ml/gdb-patches/2013-03/msg00260.html http://sourceware.org/ml/gdb-patches/2013-03/msg00380.html (note that if this change is made, it would nullify Bug 15694) -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
