...tecode. So the information of basic blocks is not what I expected. I want ot use the code as example to see how some of code optimization methods work. However, after compiling file using llvm test.c -o test, bytecode file test.bc is optimized ( llvm-dis< test.bc). Does it mean there is default optimaztion option when running llvmgcc and can I disable the option for optimiztion? By the way, I can get the almost exactly matched assemble code by using original gcc -c test.c. Thanks, Qiuyu -------------- next part -------------- An HTML attachment was scrubbed...
