emscripten-fastcomp/test/Transforms, branch master LLVM with the emscripten fastcomp javascript backend https://git.amat.us/emscripten-fastcomp/atom/test/Transforms?h=master 2014-03-06T20:56:53Z Implement integer promotion for urem, udiv, srem, and sdiv 2014-03-06T20:56:53Z Dan Gohman sunfish@mozilla.com 2014-03-06T20:23:34Z urn:sha1:68081ee62375a1d900d46f969e38330f14fb8775 The optimizer sometimes thinks it's beneficial to truncate all manner of i64 operators to narrower types, even when still wider than the platform's widest legal type. Fix a use-after-free error in GlobalOpt CleanupConstantGlobalUsers 2014-03-06T19:54:11Z Dan Gohman sunfish@mozilla.com 2014-03-06T19:51:23Z urn:sha1:d644d4a9ca114ceb5d6e69f0c0df6cd571bb33c4 This is a backport of r197178 from LLVM trunk. Use range metadata instead of introducing selects. 2014-02-28T20:39:49Z Dan Gohman sunfish@mozilla.com 2014-02-28T20:39:49Z urn:sha1:dc59054db06864099c1b1051b8ef28a30f13e6c7 When GlobalOpt has determined that a GlobalVariable only ever has two values, it would convert the GlobalVariable to a boolean, and introduce SelectInsts at every load, to choose between the two possible values. These SelectInsts introduce overhead and other unpleasantness. This patch makes GlobalOpt just add range metadata to loads from such GlobalVariables instead. This enables the same main optimization (as seen in test/Transforms/GlobalOpt/integer-bool.ll), without introducing selects. The main downside is that it doesn't get the memory savings of shrinking such GlobalVariables, but this is expected to be negligible. Move ExpandI64 into lib/Target/JSBackend. 2014-02-28T19:22:37Z Dan Gohman sunfish@mozilla.com 2014-02-26T16:47:51Z urn:sha1:0dac79df771f7708a03e724126dded4f64531bc5 Preserve alignment information when promoting integer loads and stores. 2014-02-14T19:38:16Z Dan Gohman sunfish@google.com 2014-02-14T03:24:56Z urn:sha1:71fb6dcb87d2abd302080149d4a583a5e35e3697 Preserve alignment information when splitting loads and stores. 2014-02-14T19:38:16Z Dan Gohman sunfish@google.com 2014-02-14T03:02:20Z urn:sha1:f3359807242e95f9e94bb35c0d90a73c794f1af0 Emscripten doesn't need to legalize pointers. 2014-02-13T23:04:31Z Dan Gohman sunfish@google.com 2014-02-13T22:51:59Z urn:sha1:7f2cf3ceadbcbb41227b9c0008c33d7e911e59e3 Don't leave behind unreachable blocks with illegal instructions. 2014-02-13T19:47:44Z Dan Gohman sunfish@google.com 2014-02-13T19:47:44Z urn:sha1:6f629a513c37587247dc83b961e86c177cef5d6d Revamp ExpandI64. 2014-02-13T06:30:21Z Dan Gohman sunfish@google.com 2014-02-13T02:09:52Z urn:sha1:718e02f4cea34a6f34d7a6f1f82411960bff1ba4 By using a reverse-postorder traversal of the basic blocks, we can perform this transform in a single pass. This eliminates the need for tricky coordination between the passes. Generalize PromoteIntegers to handle arbitrary bit widths. 2014-02-13T06:30:21Z Dan Gohman sunfish@google.com 2014-02-13T02:09:29Z urn:sha1:2b36da6f5426d0ea67c85fdee8016a5bbc828a23
