Change VG_(am_extend_map_client) as follows:
- Tighten up on asserts
- Simplify; as the function grows memory into a free segment, there
cannot possibly be any translations to be discarded. Free segments
do not have translations. sane_NSegment will make sure.
- Change the prototype to take in the start address of the mapping and
return a pointer to the resized segment. Previously, the code
ok = VG_(am_extend_map_client)( &d, old_seg, needL );
if (!ok)
goto eNOMEM;
VG_TRACK( new_mem_mmap, needA, needL,
old_seg->hasR, old_seg->hasW, old_seg->hasX,
was examining old_seg->hasR etc even though VG_(am_extend_map_client)
stated that *old_seg was invalid after the function returned.
That wasn't exactly a problem, but clearly looked wrong.
