I may sound stupid but can someone tell me that after applying optimization sequences randomly whether we can surely say that the final output is correct? I mean if we apply 12 options in random sequence provided by 'opt' command is the output is always correct (i.e. program does the same thing and results are same as expected) ? Is it Yes by implemention of LLVM or we have to check

While using LLVM Back-End for ANSI C: $llc -march=c <ByteCode> I get following warning message: warning: conflicting types for built-in function 'malloc' Can somehow I remove this warning through using GCC options, I know it should be on GCC Discussion Forum but still if someone can help me I would appreciate. Thanks!

By using analyze -stats -instcounts <bytecode> I can get the total number of instructions but I want to extract instruction level parallelism . That is I want to know number of add instruction that can be executed in parallel, similarly for multiply ... This would give me an idea what is upper limit of adders ( and multipliers )should be there in my hardware. Any kind of help would be
