pool allocator.
The Pool Allocator provides support to use a ref counter
to detect a pool allocator is not needed anymore.
- It is the caller responsibility to delete the PA if the ref counter
- drops to 0. In other words, this just helps the caller to manage
- the PA memory destruction but it does not fully manage it.
- Note that the usage of pool reference counting is optional. */
+ It is the caller responsibility to call VG_(addRefPA) for
+ each new reference to a pool and VG_(releasePA) when such a reference
+ disappears.
+ VG_(releasePA) will automatically call VG_(deletePA)
+ to delete the PA when the ref counter drops to 0. */
// VG_(addRefPA) indicates there is a new reference to pa.

I mean the fact that entry > in\exit from function can occur only as the first IMark at BB > (superblock). Callgrind is asking VEX to feed BBs (not SBs) of guest code to its instrumentation function. Is it true in general? As a BB is a continuous number of bytes in memory: yes, it is true that a function entry can only start at the beginning of a (dynamic) BB, and a function exit needs to be at the end of a BB (which then is detected at beginning of the next BB). Or I misunderstand logic of analysis? No, your analysis was correct.
