The post-ra scheduler was explicitly updating the depth of a node's successors after scheduling it, regardless of whether the successor was ready. This is quadratic for DAGs with transitively redundant edges. I simply removed the useless update of depth, which is lazilly computed later. Fixes <rdar://problem/9044332> compiler takes way too long to build TextInput. llvm-svn: 130992

BuildSchedGraph was quadratic in the number of calls in the basic block. After this fix, it keeps only a single call at the top of the DefList so compile time doesn't blow up on large blocks. This reduces postRA sched time on an external test case from 81s to 0.3s. Although r130800 (reduced ARM register alias defs) also partially fixes the issue by reducing the constant overhead of checking call interference by an order of magnitude. Fixes <rdar://problem/7662664> very poor compile time with post RA scheduling. llvm-svn: 130943

Joining physregs is inherently dangerous because it uses a heuristic to avoid creating invalid code. Linear scan had an emergency spilling mechanism to deal with those rare cases. The new greedy allocator does not. The greedy register allocator is much better at taking hints, so this has almost no impact on code size and quality. The few cases where it matters show up as unit tests that now have -join-physregs enabled explicitly. llvm-svn: 130896

landing pad as its successor. SjLj exception handling jumps to the correct landing pad via a switch statement that's generated right before code-gen. Loosen the constraint in the machine instruction verifier to allow for this. Note, this isn't the most rigorous check since we cannot determine where that switch statement came from. But it's marginally better than turning this check off when SjLj exceptions are used. <rdar://problem/9187612> llvm-svn: 130881
