2012-09-07perf tools: add NO_BACKTRACE for application self-debuggingIrina Tirdea
perf has support for self-debugging by defining dump_stack function. This function uses backtrace and backtrace_symbols functions defined as GNU extensions. In Android, bionic does not offer support for these functions and compilation will fail with the following error: target C: libperf <= tools/perf/util/util.c tools/perf/util/util.c:4:22: fatal error: execinfo.h: No such file or directory compilation terminated. Add a compile-time option (NO_BACKTRACE) to enable or disable self-debugging functionality in perf. This can also help in debugging since it offers the possibility to turn on/off printing the backtrace.

2012-09-05perf tools: Fix x86 builds with ARCH specified on the command lineDavid Ahern
e.g., compiling i386 on x86_64 using: $ make -C tools/perf ARCH=i386 fails with: CC /tmp/pbuild/util/evsel.o In file included from util/evsel.c:21:0: util/perf_regs.h:5:23: fatal error: perf_regs.h: No such file or directory compilation terminated. Adding V=1 you see that the include argument for the arch is '-Iarch/i386/include' is wrong. It is supposed to be -Iarch/x86/include per the redefinition of ARCH in the Makefile. According to the make manual, http://www.gnu.org/software/make/manual/make.html#Override-Directive: "If a variable has been set with a command argument (see Overriding Variables), then ordinary assignments in the makefile are ignored. If you want to set the variable in the makefile even though it was set with a command argument, you can use an override directive ..." Make it so.

2012-08-20perf tools: Fix include order for bison/flex-generated C filesBen Hutchings
When we use a separate output directory, we add util/ to the include path for the generated C files. However, this is currently added to the end of the path, behind /usr/include/slang and /usr/include/gtk-2.0 if use of the respective libraries is enabled. Thus the '#include "../perf.h"' in util/parse-events.l can actually include /usr/include/perf.h if it exists. Move '-Iutil/' ahead of all the other preprocessor options.

2012-04-25perf: Have perf use the new libtraceevent.a librarySteven Rostedt
The event parsing code in perf was originally copied from trace-cmd but never was kept up-to-date with the changes that was done there. The trace-cmd libtraceevent.a code is much more mature than what is currently in perf. This updates the code to use wrappers to handle the calls to the new event parsing code. The new code requires a handle to be pass around, which removes the global event variables and allows more than one event structure to be read from different files (and different machines). But perf still has the old global events and the code throughout perf does not yet have a nice way to pass around a handle. A global 'pevent' has been made for perf and the old calls have been created as wrappers to the new event parsing code that uses the global pevent. With this change, perf can later incorporate the pevent handle into the perf structures and allow more than one file to be read and compared, that contains different events.

2012-04-25perf: Separate out trace-cmd parse-events from perf filesSteven Rostedt
Move the trace-event-parse.c code that originally came from trace-cmd into their own files. The new file will be called trace-parse-events.c, as the name of trace-cmd's file was parse-events.c too, but it conflicted with the parse-events.c file in perf that parses the command line. This tries to update the code with mimimal changes. Perf specific code stays in the trace-event-parse.[ch] files and the common parsing code is now in trace-parse-events.c and trace-parse-events.h.
