[LLVMdev] [PATCH] Re: Overflow trap
The enclosed patch adds a llvm.x86.int(i8) intrinsic expanding to the INT or INT3 instruction as appropriate. I haven't yet figured out the best way to select for the INTO instruction across basic blocks (hints would be welcome), but that can be added later with no changes in semantics.

[LLVMdev] Overflow trap
After chatting on IRC, Peter wants a very specific interrupt (int4 on x86). I suggested he add a new llvm.x86.int(i32) intrinsic, and use the existing branch on llvm.sadd.with.overflow intrinsic. The x86 backend can then turn jo+int4 into into when reasonable.
