[llvm-commits] [PATCH] Emit ARM EHABI unwinding instructions for 2 more Thumb instructions

[Evgeniy Stepanov]

Hm, I've got a problem here. Maybe you can help me?

The following fails:

# cat 1.ii
void f() {
}
void g() {
    f();
}
# ./Release+Asserts/bin/clang -ccc-host-triple arm-linux-gnueabi 1.ii
-S -mthumb  -mllvm -arm-enable-ehabi

How do I build an llc command line?
The naive

./Release+Asserts/bin/llc -march=thumb -arm-enable-ehabi -O=0 <1.ii

does not expose the bug.
