2009-10-29perf tools: Delay loading symtabs till we hit a map with itArnaldo Carvalho de Melo
So that we can have a quicker start on perf top and even speedups in the other tools, as we can have maps with no hits, so no need to load its symtabs.

2009-10-23perf tools: Unify debug messages mechanismsArnaldo Carvalho de Melo
We were using eprintf in some places, that looks at a global 'verbose' level, and at other places passing a 'v' parameter to specify the verbosity level, unify it by introducing pr_{err,warning,debug,etc}, just like in the kernel.

2009-10-20perf annotate: Use the sym_priv_size area for the histogramArnaldo Carvalho de Melo
We have this sym_priv_size mechanism for attaching private areas to struct symbol entries but annotate wasn't using it, adding private areas to struct symbol in addition to a ->priv pointer. Scrap all that and use the sym_priv_size mechanism.

2009-10-20perf tools: Add ->unmap_ip operation to struct mapArnaldo Carvalho de Melo
We need this because we get section relative addresses when reading the symtabs, but when a tool like 'perf annotate' needs to match these address to what 'objdump -dS' produces we need the address + section back again. So in annotate now we look at the 'struct hist_entry' instances (that weren't really being used) so that we iterate only over the symbols that had some hit and get the map where that particular hit happened so that we can get the right address to match with annotate. Verified that at least: perf annotate mmap_read_counter # Uses the ~/bin/perf binary perf annotate --vmlinux /home/acme/git/build/perf/vmlinux intel_pmu_enable_all on a 'perf record perf top' session seems to work.
