Arnold Schwaighofer	51193f4c82	These tests require __swift_debug_verifyTypeLayoutAttribute which is not ABI or available on OS stdlibs ... Interpreter/multi_payload_extra_inhabitant.swift Interpreter/struct_extra_inhabitants.swift Mark the test as unsupported when running the tests with the OS' stdlib. rdar://54749176	2019-08-27 09:06:12 -07:00
Joe Groff	bf593b420c	IRGen: Fix extra inhabitants of multi-payload enums with more spare bits than tag bits. ... Because layout minimizes the number of tag bits used, and favors high spare bits, the spare bit representations end up overlapping the extra inhabitant representations, since we just counted down from -1. If there are fewer tag bits than total spare bits, rotate the extra inhabitant values so they correctly line up with the tag representations in this situation. rdar://problem/46468090	2018-12-06 13:01:04 -08:00
Joe Groff	4428d479aa	Fix ClusteredBitVector::fromAPInt for zero-sized vectors. ... A one-bit zero APInt is a reasonable stand-in for everywhere we need this.	2018-11-14 14:05:21 -08:00
Joe Groff	ca402f19b1	Give multi-payload enums extra inhabitants. ... Previously, they would forward their unused spare bits to be used by other multi-payload enums, but did not implement anything for single-payload extra inhabitants.	2018-11-13 18:08:01 -08:00
