Hello!

Does LDC has its own counterpart for GCC's __builtin_expect?

To be more specific, I need something to replicate the behaviour of these two macros:

#define likely(x)       __builtin_expect(!!(x), 1)
#define unlikely(x)     __builtin_expect(!!(x), 0)

you can find llvm_expect(T)(T val, T expectedVal) in the module ldc.intrinsics

I'm trying to port LDC to FreeBSD on PowerPC64.  I've developed an initial set of patches and I'm able to build LDC 0.17.5(bootstrap).

However, all but a handful of tests fail with segfault.  How do I set debug to capture and diagnose the cause of the segfaults?
