Backtrace/output from LLC
Running the following in llc ends with an LLVM assertion failure:
define void @foo () {
%1 = alloca half
store half 0xH42CC, half* %1 ; 0xH42CC = 3.4
%2 = load half* %1
ret void
}
(credit to Alessio Giovanni Baroni on the LLVM mailing list for the example).
I attached backtrace/output from llc. This happens on both 3.2 and 3.3.
