This is because in #60187 we split the fields into two groups, a "prefix" non-overlap region and an overlap region, and lay them out separately. This can introduce unnecessary padding bytes between the two groups. In every single case in the Fuchsia build, it was due to there being only a single variant being used in the overlap region. This means that we aren't doing any overlapping, period. So it's better to combine the two regions into one and lay out all the fields at once, which is what this change does. r? @cramertj cc @eddyb @Zoxc 2019-08-03T01:06:50+00:00 Tyler Mandry tmandry@gmail.com 2019-08-03T01:06:15+00:00 urn:sha1:9d4ca879b88e3a21354dcda458d7e7f7ff6370b2 2019-07-27T15:56:17+00:00 Vadim Petrochenkov vadim.petrochenkov@gmail.com 2019-07-26T23:07:23+00:00 urn:sha1:5486cc69bdcc1c0027d7d06cd7630a2c48e3b063 2019-07-27T15:56:16+00:00 Vadim Petrochenkov vadim.petrochenkov@gmail.com 2019-07-26T22:33:01+00:00 urn:sha1:9be35f82c1abf2ecbab489bca9eca138ea648312 2019-07-27T15:56:13+00:00 Vadim Petrochenkov vadim.petrochenkov@gmail.com 2019-07-26T21:54:25+00:00 urn:sha1:ca9faa52f5ada0054b1fa27d97aedf448afb059b 2019-07-26T16:56:45+00:00 Mazdak Farrokhzad twingoow@gmail.com 2019-07-26T16:56:45+00:00 urn:sha1:5ffdca77c44f3233abe389890ba73e966d90406d Remove vector fadd/fmul reduction workarounds The bugs that this was working around have been fixed in LLVM 9. r? @gnzlbg 2019-07-25T21:21:00+00:00 Mazdak Farrokhzad twingoow@gmail.com 2019-07-25T21:21:00+00:00 urn:sha1:e1de70b04548b2e899fcf0da09c29600cc05325e Turn `#[global_allocator]` into a regular attribute macro It was a 99% macro with exception of some diagnostic details. As a result of the change, `#[global_allocator]` now works in nested modules and even in nameless blocks.
