llvm with tablegen backend for capstone disassembler

LiveDebugVariables unconditionally propagates all DBG_VALUE down the dominator tree, which happens to work fine if there already is another DBG_VALUE or the DBG_VALUE happends to describe a single-assignment vreg but is otherwise wrong if the DBG_VALUE is coming from only one of the predecessors. In r255759 we introduced a proper data flow analysis scheduled after LiveDebugVariables that correctly propagates DBG_VALUEs across basic block boundaries. With the new pass in place, the incorrect propagation in LiveDebugVariables can be retired witout loosing any of the benefits where LiveDebugVariables happened to do the right thing. llvm-svn: 256188 |
