Subject: Eliminate 64-bit compiler warnings in atomic_ops_malloc
X-Git-Tag: libatomic_ops-7_4_0~83
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0ff771b50a4eb1e1c8125f7ee1501e74ea116b9e;p=platform%2Fupstream%2Flibatomic_ops.git

Eliminate 64-bit compiler warnings in atomic_ops_malloc

* src/atomic_ops_malloc.c (add_chunk_as): Cast shifted value to size_t
(the type of assigned variable, at least to eliminate compiler warning
for 64-bit targets).
* src/atomic_ops_malloc.c (AO_free): Cast (*base) to int (the type of
assigned variable) to eliminate MS VC compiler warning.
