https://sourceware.org/bugzilla/show_bug.cgi?id=29085 Bug ID: 29085 Summary: Start messages printed by "gprofng collect app" with a keyword Product: binutils Version: 2.39 (HEAD) Status: NEW Severity: enhancement Priority: P2 Component: gprofng Assignee: vladimir.mezentsev at oracle dot com Reporter: ruud.vanderpas at oracle dot com Target Milestone: --- This is a Request for Enhancement to start the messages printed by "gprofng collect app" with a keyword. For example, something like this: [gprofng] Creating experiment directory test.1.er (Process ID: 12345) Currently these messages are interleaved with the application output and this could not only be confusing, but may also not be desirable. If such a keyword is added, it is easier to identify such messages, or filter them out. -- You are receiving this mail because: You are on the CC list for the bug.
