assert(0) -> LLVM_UNREACHABLE. · 56d06597

Torok Edwin authored Jul 11, 2009

Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Evan Cheng authored Jul 11, 2009

Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically.

A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well.
