[LLVMdev] Generating unusual instruction

[Vikram Singh]

I have seen that most of the targets do comparison and branching
in two separate instructions e.g. 'cmpl' followed by 'br' in x86 or the
like.
LLVM IR is also in same manner.

I want to implement comparison+branching in one instruction like

       beq r1, r2, .label   #if r1==r2 then jump to .label

How to merge two instruction into one.

Regards
Vikram Singh
