<pre>Reduced test case:
$ cat bug_conv_f32_to_i64.c
// Compile with clang -target=powerpc-unknown-unknown -c -mcpu=pwr7
unsigned long long testullf(float arg) { return arg; }
$ clang -target=powerpc-unknown-unknown -c -mcpu=pwr7 bug_conv_f32_to_i64.c
Do not know how to custom type legalize this operation!
UNREACHABLE executed at $LLVM_SRC/lib/Target/PowerPC/PPCISelLowering.cpp:7729!
Same thing happens when llc is run on the resulting ll/bc file.</pre>
