Subject: keep address space qualifier of pointers
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a3b4c999f0fe575a05b3c70dd61ccb4b50893fb7;p=contrib%2Fbeignet.git

keep address space qualifier of pointers

for built-in function with address-space-qualified pointers,
keep address space when accessing the pointers.
