Hello. This is Byungchan An.
I have a question on the llvm IR.
I'm compiling grep and generate bitcode. Here, I found something weird such
as the following.
cond.true1536: ; preds = %while.body1531
br *i1 false*, label %if.end1558, label %if.then1557, !dbg !6453
Until now, what I examined is register value calculated as a result of
icmp, rcmp, trunk, and phi.
So, this makes me really confused... What type of that value is and how can
this be generated? Any simple example that can lead to this bit code?
Is there anybody who can help me?
Thanks.
