We're not very good at handling out-of-memory conditions in general, but
this change at least gives the caller the option of handling it gracefully
and without memory leaks.
This happens to fix an error in out-of-memory handling in i965, which has
the following code in brw_bufmgr.c:
node = util_dynarray_grow(vma_list, sizeof(struct vma_bucket_node));
if (unlikely(!node))
return 0ull;
Previously, allocation failure for util_dynarray_grow wouldn't actually
return NULL when the dynarray was previously non-empty.
v2:
- make util_dynarray_ensure_cap a no-op on failure, add MUST_CHECK attribute
- simplify the new capacity calculation: aside from avoiding a useless loop
when newcap is very large, this also avoids an infinite loop when newcap
is larger than 1 << 31
