On 64-bit powerpc, __u64 is defined to be unsigned long rather than unsigned long long. This causes compiler warnings every time we print a __u64 value with %Lx. Rather than changing __u64, we define our own u64 to be unsigned long long on all architectures, and similarly s64 as signed long long. For consistency we also define u32, s32, u16, s16, u8 and s8. These definitions are put in a new header, types.h, because these definitions are needed in util/string.h and util/symbol.h. The main change here is the mechanical change of __[us]{64,32,16,8} to remove the "__". The other changes are: * Create types.h * Include types.h in perf.h, util/string.h and util/symbol.h * Add types.h to the LIB_H definition in Makefile * Added (u64) casts in process_overflow_event() and print_sym_table() to kill two remaining warnings.

The Git utils came with a ctype replacement that doesn't provide isprint(). Add a replacement. Solves a build bug on certain distros.

When we have a colored line in perf annotate, ie a middle/high overhead one, it's sometimes useful to get the matching line and filename from the source file, especially this path prepares to another subsequent one which will print a sorted summary of midle/high overhead lines in the beginning of the output. Filename:Lines have the same color than the concerned ip lines. It can be slow because it relies on addr2line. We could also use objdump with -l but that implies we would have to bufferize objdump output and parse it to filter the relevant lines since we want to print a sorted summary in the beginning.

A build error slipped in: builtin-report.c: In function ‘hist_entry__fprintf’: builtin-report.c:711: error: format ‘%12d’ expects type ‘int’, but argument 3 has type ‘uint64_t’ Because we got a bit sloppy with those types. uint64_t really sucks, because there's no printf format for it. So standardize on __u64 instead - for all types that go to or come from the ABI (which is __u64), or for values that need to be large enough even on 32-bit.

This patch adds support for profiling JIT generated code to 'perf report'. A JIT compiler is required to generate a "/tmp/perf-$PID.map" symbols map that is parsed when looking and displaying symbols. Thanks to Peter Zijlstra for his help with this patch! Example "perf report" output with the Jato JIT: # # (40311 samples) # # Overhead Command Shared Object Symbol # ........ ................ ......................... ...... # 97.80% jato /tmp/perf-11915.map [.] Fibonacci.fib(I)I 0.56% jato 00000000b7fa023b 0x000000b7fa023b 0.45% jato /tmp/perf-11915.map [.] Fibonacci.main([Ljava/lang/String;)V 0.38% jato [kernel] [k] get_page_from_freelist 0.06% jato [kernel] [k] kunmap_atomic 0.05% jato ./jato [.] utf8Hash 0.04% jato ./jato [.] executeJava 0.04% jato ./jato [.] defineClass Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: NPekka Enberg <penberg@cs.helsinki.fi> Cc: a.p.zijlstra@chello.nl Cc: acme@redhat.com LKML-Reference: <Pine.LNX.4.64.0906082111590.12407@melkki.cs.Helsinki.FI> Signed-off-by: NIngo Molnar <mingo@elte.hu>

On architectures/CPUs without PMU support but with perfcounters enabled 'perf top' currently fails because it cannot create a cycle based hw-perfcounter. Fall back to the cpu-clock-tick sw-perfcounter in this case, which is hrtimer based and will always work (as long as perfcounters is enabled).

the "perf report" utility crashed in some circumstances because the "sym" stack variable was not initialized before used (as also proven by valgrind). With this fix both the crash goes away and valgrind no longer complains.
