Chandler Carruth c5861be643 [PM] Add (very skeletal) support to opt for running the new pass ... manager. I cannot emphasize enough that this is a WIP. =] I expect it to change a great deal as things stabilize, but I think its really important to get *some* functionality here so that the infrastructure can be tested more traditionally from the commandline. The current design is looking something like this: ./bin/opt -passes='module(pass_a,pass_b,function(pass_c,pass_d))' So rather than custom-parsed flags, there is a single flag with a string argument that is parsed into the pass pipeline structure. This makes it really easy to have nice structural properties that are very explicit. There is one obvious and important shortcut. You can start off the pipeline with a pass, and the minimal context of pass managers will be built around the entire specified pipeline. This makes the common case for tests super easy: ./bin/opt -passes=instcombine,sroa,gvn But this won't introduce any of the complexity of the fully inferred old system -- we only ever do this for the *entire* argument, and we only look at the first pass. If the other passes don't fit in the pass manager selected it is a hard error. The other interesting aspect here is that I'm not relying on any registration facilities. Such facilities may be unavoidable for supporting plugins, but I have alternative ideas for plugins that I'd like to try first. My plan is essentially to build everything without registration until we hit an absolute requirement. Instead of registration of pass names, there will be a library dedicated to parsing pass names and the pass pipeline strings described above. Currently, this is directly embedded into opt for simplicity as it is very early, but I plan to eventually pull this into a library that opt, bugpoint, and even Clang can depend on. It should end up as a good home for things like the existing PassManagerBuilder as well. There are a bunch of FIXMEs in the code for the parts of this that are just stubbed out to make the patch more incremental. A quick list of what's coming up directly after this: - Support for function passes and building the structured nesting. - Support for printing the pass structure, and FileCheck tests of all of this code. - The .def-file based pass name parsing. - IR priting passes and the corresponding tests. Some obvious things that I'm not going to do right now, but am definitely planning on as the pass manager work gets a bit further: - Pull the parsing into library, including the builders. - Thread the rest of the target stuff into the new pass manager. - Wire support for the new pass manager up to llc. - Plugin support. Some things that I'd like to have, but are significantly lower on my priority list. I'll get to these eventually, but they may also be places where others want to contribute: - Adding nice error reporting for broken pass pipeline descriptions. - Typo-correction for pass names. llvm-svn: 198998		2014-01-11 08:16:35 +00:00
