tools lib traceevent: Ignore TRACEEVENT-CFLAGS file

2012-07-25T14:54:44+00:00

The TRACEEVENT-CFLAGS file is used to detect any change on compiler
flags. Just ignore it.

tools lib traceevent: Detect build environment changes

2012-07-25T14:54:06+00:00

Cross compiling perf requires setting ARCH and CROSS_COMPILE variables,
but libtraceevent couldn't detect the changes so it ends up believing no
recompiling is required. Thus the linker failed like:

     LINK perf
 ../lib/traceevent//libtraceevent.a: member ../lib/traceevent//libtraceevent.a(event-parse.o) in archive is not an object
 collect2: ld returned 1 exit status
 make: *** [perf] Error 1

This patch fixes this by adding TRACEEVENT-CFLAGS file like
PERF-CFLAGS to track those changes.

tools lib traceevent: Cleanup realloc use

2012-07-04T04:40:31+00:00

The if branch is completely unnecessary since 'realloc' can handle
NULL pointers for the first parameter.

This patch is just an adoption of Ulrich Drepper's recent patch on
perf tools.

tools lib traceevent: Add missing break in make_bprint_args

2012-07-04T04:40:31+00:00

In the current code we assign vsize=8 and then fall through to the
default and assign vsize=1. -> probably the break is missing here,
otherwise we can remove the case.

tools lib traceevent: Check return value of arg_to_str()

2012-07-04T04:40:31+00:00

The arg_to_str() can fail so we should handle that case properly.

tools lib traceevent: Check result of malloc() during reading token

2012-07-04T04:40:31+00:00

The malloc can fail so the return value should be checked.  For now,
just use malloc_or_die().

tools lib traceevent: Do not call add_event() again if allocation failed

2012-07-04T04:40:31+00:00

When memory allocation for the field name is failed, do not goto
event_failed since we added the event already.

2012-07-04T04:40:31+00:00

It seems PEVENT_FUNC_ARG_STRING missed passing the allocated string to
the args array.  Fix it.
