commit b100897fdb986b1338099351e6b60a187572ce47
Author: Mark Wielaard <mjw@redhat.com>
Date: Fri Oct 21 13:34:21 2011 +0200
Extend vma_map entry vm_end range when additional segments are mapped.
Once registered, we may want to extend an earlier registered region.
A segment might be mapped with different flags for different offsets.
If so we want to record the extended range so we can address more
precisely to module names and symbols.
* runtime/task_finder_vma.c (__stp_tf_get_vma_map_entry_end_internal):
New function.
(stap_extend_vma_map_info): Likewise.
* runtime/vma.c (_stp_vma_mmap_cb): Call stap_extend_vma_map_info().
