Bug 1163171 - part 5 - remove arm-specific hacks in typed array implementation; r=lth
|
|
|
|
clang does not have the specific problem that led to this hack in the
|
|
first place, so we can remove the hack. (The hack also causes issues
|
|
with clang; it complains that you can't pass `volatile T*` into the
|
|
intrinsics that we're using for atomic operations.)
