Subject: [LLVMdev] insert nop instruction

 

Hi.

I need to write a function pass that insert nop instruction in function. Examples of these instructions are: %nop = add i1 0, 0 or %nop = alloca i1, i1 0. This link couldn't help me: http://llvm.org/docs/ProgrammersManual.html#creating-and-inserting-new-instructions <https://urldefense.proofpoint.com/v2/url?u=http-3A__llvm.org_docs_ProgrammersManual.html-23creating-2Dand-2Dinserting-2Dnew-2Dinstructions&d=AwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Mfk2qtn1LTDThVkh6-oGglNfMADXfJdty4_bhmuhMHA&m=qXjJRaqkQWeOVtPcUv65c1zR2hwz2FyxkyPKUDcEsBM&s=CnMC85PvQDV1ouDHE2aQz5LytBiguUJ3JiOkMez73dg&e=> 

I need a clear example about inserting new instruction. Anyone can help me?

Thanks.
