annotate tests/mini/union7.d @ 978:6a32d2e18175
Fix a latent bug in the asm code.
I think that technically, using "*m0" instead of "*0" allows LLVM to pick
between using the same memory as output 0 and using a new memory location.
(So far I haven't been able to construct a testcase that actually breaks
because of this, though)
