perf tools: Introduce event_format__fprintf method

2015-02-06T10:46:37Z

The existing one, event_format__print() uses stdout unconditionally, and 'perf trace' needs to use it to format into a file that may have been set by the user, i.e. 'trace -o file.output'.

perf tools: Add trace-event object

2013-12-04T18:20:52Z

Add trace-event object to keep together 'struct pevent' object with its loaded plugins with following interface: int trace_event__init(struct trace_event *t); - Initalizes 'struct pevent' object and loads plugins for it void trace_event__cleanup(struct trace_event *t); - Cleanups both 'struct pevent' and plugins Signed-off-by: Jiri Olsa Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Steven Rostedt Link: http://lkml.kernel.org/r/1386076182-14484-10-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Fix old GCC build error in trace-event-parse.c:parse_proc_kallsyms()

2013-09-19T18:08:47Z

Old GCC (4.1) does not see through the code flow of parse_proc_kallsyms() and gets confused about the status of 'fmt': util/trace-event-parse.c: In function ‘parse_proc_kallsyms’: util/trace-event-parse.c:189: warning: ‘fmt’ may be used uninitialized in this function make: *** [util/trace-event-parse.o] Error 1 Help out GCC by initializing 'fmt' to NULL.

perf tools: remove sscanf extension %as

2012-09-24T14:49:31Z

perf uses sscanf extension %as to read and allocate a string in the same step. This is a non-standard extension only present in new versions of glibc. Replacing the use of sscanf and %as with strtok_r calls in order to parse a given string into its components. This is needed in Android since bionic does not support %as extension for sscanf.

perf tools: Use __maybe_used for unused variables

2012-09-11T15:19:15Z

perf defines both __used and __unused variables to use for marking unused variables. The variable __used is defined to __attribute__((__unused__)), which contradicts the kernel definition to __attribute__((__used__)) for new gcc versions. On Android, __used is also defined in system headers and this leads to warnings like: warning: '__used__' attribute ignored __unused is not defined in the kernel and is not a standard definition. If __unused is included everywhere instead of __used, this leads to conflicts with glibc headers, since glibc has a variables with this name in its headers. The best approach is to use __maybe_unused, the definition used in the kernel for __attribute__((unused)). In this way there is only one definition in perf sources (instead of 2 definitions that point to the same thing: __used and __unused) and it works on both Linux and Android. This patch simply replaces all instances of __used and __unused with __maybe_unused.
