86fa15a8a2
Fixes an issue where there was a chance that an exception would be thrown when out of memory rather than returning an appropriate VkResult code. Additionally introduces a noncopyable utility class that can be used to mark classes that should not have copy semantics Change-Id: I1f84dc9bb1ea96db2a88a90d56adbee78b17c5e3 Signed-off-by: Normunds Rieksts <normunds.rieksts@arm.com>
