2012-05-24tools lib traceevent: Fix freeing arg on process_dynamic_array()Namhyung Kim

If set_op_prio() failed, the token will be freed at out_free, then arg->op.op would turn out to be a dangle pointer.

2012-05-24tools lib traceevent: Allow expressions in __print_symbolic() fieldsStefan Hajnoczi
The __print_symbolic() function takes a sequence of key-value pairs for pretty-printing a constant. The new kvm:kvm_exit print fmt uses the expression: __print_symbolic(..., { 0x040 + 1, "DB excp" }, ...) Currently only atoms are supported and this print fmt fails to parse. This patch adds support for expressions instead of just atoms so that 0x040 + 1 is parsed successfully.

2012-04-25parse-events: Handle opcode parsing errorVaibhav Nagarnaik
If an invalid opcode is encountered in parsing event print format, the trace-cmd calls exit() without parsing any other events. This patch adds handling for such an error where the get_op_prio() is called. If the return value is -1, then the event print format parsing is skipped and parsing continues.

2012-04-25parse-events: Handle invalid opcode parsing gracefullyVaibhav Nagarnaik
If an invalid opcode is encountered, trace-cmd exits with an error. Instead it can be treated as a soft error where the event's print format is not parsed and its binary data is dumped out. This patch adds a return value to arg_num_eval() function to indicate if the parsing was successful. If not, then the error is considered soft and the parsing of the offending event fails.

2012-04-25tools/events: Add files to create libtraceevent.aSteven Rostedt
Copy over the files from trace-cmd to the Linux tools directory such that applications like perf and latencytrace can use the more advanced parsing code. Because some of the file names of perf conflict with trace-cmd file names, the trace-cmd files have been renamed as follows: parse-events.c ==> event-parse.c parse-events.h ==> event-parse.h utils.h ==> event-utils.h The files have been updated to handle the changes to the header files but other than that, they are identical to what was in the trace-cmd repository. The history of these files, including authorship is available at the git repo: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git The Makefile was also copied over, but most of it was removed to focus on the parse-events code first. The parts of the Makefile for the plugins have also been removed, but will be added back when the plugin code is copied over as well. But that may be in its own separate directory.
