...if it is not clear enough. Mainly, what I need to know statically is the beginning of the code contained in the BasicBlock BB4 and the size of jump, in the generated code.

Hello- Doing control-flow (jumps and/or labels) in inline asm is a really bad idea. What are you trying to achieve?

Hi LLVM-devs, I am looking for a way to prevent an instruction to be executed more than once, or duplicated .. I know that by default everything can be duplicated, but is there a work-around? The structure of the code is BB1 BB2 | | | | | | |----------| | v BB3 where the first instruction in BB3 is inserting an inline assembly
