2012-09-11perf tools: Use __maybe_used for unused variablesIrina Tirdea1-3/+4
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.

2012-05-29perf ui browser: Stop using 'self'Arnaldo Carvalho de Melo1-90/+90
Stop using this python/OOP convention, doesn't really helps. Will do more from time to time till we get it cleaned up in all of /perf.

2012-05-03perf annotate browser: More clearly separate columnsArnaldo Carvalho de Melo1-7/+7
The first column (columns in the near future) are for the per line event overhead(s), that only appear when they are not zero. To clearly separate it, add back a solid vertical line, with just one colour, not influenced by the per line overheads. Then have the addr/offset column, then optionally the dynamic (static in the future) jump->target arrows, if 'j' enables it. Then the instructions.

It figures out the direction and draws downwards arrows too if that is the case.

2012-04-24perf annotate browser: Initial loop detectionArnaldo Carvalho de Melo1-0/+39
Simple algorithm, just look for the next backward jump that points to before the cursor. Then draw an arrow connecting the jump to its target. Do this as you move the cursor, entering/exiting possible loops. Ex (graph chars replaced to avoid mail encoding woes): avc_has_perm_flags 0.00 | nopl 0x0(%rax) 5.36 |+-> 68: mov (%rax),%rax 5.15 || test %rax,%rax 0.00 || v je 130 2.96 || 74: cmp -0x20(%rax),%ebx 47.38 || lea -0x20(%rax),%rcx 0.28 || ^ jne 68 3.16 || cmp -0x18(%rax),%dx 0.00 |+------^ jne 68 4.92 | cmp 0x4(%rcx),%r13d 0.00 | v jne 68 1.15 | test %rcx,%rcx 0.00 | v je 130 Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-5gairf6or7dazlx3ocxwvftm@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2012-04-20ui browser: Add method to write graphical charactersArnaldo Carvalho de Melo1-0/+7
To save typing on the switch char set slang stuff. It also helps in removing more slang direct calls, wrapping them at the ui_browser level, where at some point I'll try to implement those in terms of GTK+.
