StoreManager::CastRegion:
- Don't layer TypedViewRegions on top of any region except
SymbolicRegions and AllocaRegions. This follows from my offline
discussion within Zhongxing about how TypedViewRegions really only
represent memory getting re-appropriated for a new purpose.
Fallout from this change:
- Move test case from xfail_rdar_6440393.m to misc-ps-64.m
(it now passes).
- test/Analysis/fields.c now fails for region store (crash).
Marking XFAIL.
- test/Analysis/rdar-6441136-region.c now fails (only runs with region store).
Marking XFAIL.
Diagnosis: The analyzer now correctly identifies an early out-of-bounds memory
access then the one flagged:
rdar-6541136-region.c:17:3: warning: Load or store into an out-of-bound memory position.
*p = 1;
^~
Changing the line:
char *p = (void*) &wonky[1];
to
char *p = (void*) &wonky[0];
(which should delay the buffer overrun) causes region store to crash, probably
because it expects a TypedViewRegion.
- test/Analysis/casts.c (region store) now fails (crash).
Marking XFAIL.
