% Many of these tests fail on MoltenVK because of a bug in Metal, which causes
|
|
% SIMD operations (i.e., wave operations for Apple) to be hoisted out of the
|
|
% "if"statement, thereby changing which threads (i.e., wave groups for Apple)
|
|
% appear as active. This was reported to Apple as FB15624583.
