Minimised test case
I'm hitting the following when building the attached test case with clang 3.8:
Assertion failed: (BitWidth == RHS.BitWidth && "Comparison requires equal bit
widths"), function operator==, file
/home/at718/freebsd/lib/clang/libllvmselectiondag/../../../contrib/llvm/include/llvm/ADT/APInt.h,
line 978.
I'm building with:
cc -cc1 -triple aarch64-unknown-freebsd11.0 -emit-obj csqrt_test-cc283e.c
The stack trace is:
