@ -431,6 +431,14 @@ kmem.*::
This option decides which allocator is to be analyzed if neither
'--slab' nor '--page' option is used. Default is 'slab'.
record.*::
record.build-id::
This option can be 'cache', 'no-cache' or 'skip'.
'cache' is to post-process data and save/update the binaries into
the build-id cache (in ~/.debug). This is the default.
But if this option is 'no-cache', it will not update the build-id cache.
'skip' skips post-processing and does not update the cache.
