With this patch, we still do so when the pair is an immediate value, but we use the `i8` memory type when the value is loaded or stored as an LLVM aggregate. So `(bool, bool)` looks like an `{ i1, i1 }` immediate, but `{ i8, i8 }` in memory. When a pair is a direct function argument, `PassMode::Pair`, it is still passed using the immediate `i1` type, but as a return value it will use the `i8` memory type. Also, `bool`-like` enum tags will now use scalar pairs when possible, where they were previously excluded due to optimization issues. 2018-05-17T20:27:29+00:00 Nikita Popov nikita.ppv@gmail.com 2018-05-14T13:20:51+00:00 urn:sha1:12308139ec76dfa050ed012606495250391aaf74 This used to be disabled due to LLVM bugs in the handling of noalias information in conjunction with unwinding. However, according to #31681 all known LLVM bugs have been fixed by LLVM 6.0, so it's probably time to reenable this optimization. Noalias annotations will not be emitted by default if either -C panic=abort (as previously) or LLVM >= 6.0 (new). -Z mutable-noalias=no is left as an escape-hatch to allow debugging problems suspected to stem from this change. 2018-04-26T07:30:28+00:00 Anthony Ramine n.oxyde@gmail.com 2018-03-27T14:44:03+00:00 urn:sha1:3ca6ad922eb6d8c3139d961c844a0194eaf58770 2018-03-26T15:35:29+00:00 Anthony Ramine n.oxyde@gmail.com 2018-03-26T14:26:03+00:00 urn:sha1:bda718fd255237167f08198b0fc80ab0d484d58e 2018-01-30T22:23:25+00:00 Eduard-Mihai Burtescu edy.burt@gmail.com 2018-01-30T22:23:25+00:00 urn:sha1:973756d715f9caaeee44e9387f5c60458ae5c4fc 2017-11-19T15:58:38+00:00 Eduard-Mihai Burtescu edy.burt@gmail.com 2017-11-19T10:13:24+00:00 urn:sha1:88e4d2c2918428d55e34cd57c11279ea839c8822
