From aa708763d30384c0da0b0779be96ba45f65773df Mon Sep 17 00:00:00 2001 From: Fangrui Song Date: Fri, 3 Jan 2020 10:55:30 -0800 Subject: [MC] Add parameter `Address` to MCInstPrinter::printInst printInst prints a branch/call instruction as `b offset` (there are many variants on various targets) instead of `b address`. It is a convention to use address instead of offset in most external symbolizers/disassemblers. This difference makes `llvm-objdump -d` output unsatisfactory. Add `uint64_t Address` to printInst(), so that it can pass the argument to printInstruction(). `raw_ostream &OS` is moved to the last to be consistent with other print* methods. The next step is to pass `Address` to printInstruction() (generated by tablegen from the instruction set description). We can gradually migrate targets to print addresses instead of offsets. In any case, downstream projects which don't know `Address` can pass 0 as the argument.
