[LLVMdev] BlockFrequencyImpl asserts on multiple edges between same MBBs with different weights in LLVM 3.2
We are developing a new backend for a custom processor using LLVM.
After updating to LLVM 3.2, we run into an assertion in

for ( ... ) {
switch (i) {
case 100: // do something
break;
case 102: // do something else
break;
case 103: // do some more
