(#8677)2025-10-10T21:34:56+00:00Yong Heyonghe@outlook.com2025-10-10T21:34:56+00:00urn:sha1:462ea4e66569efa978e4057ea2d041c69d4a729b
Closes #8673.
The issue is that we use the RTTI field of an existential to check if it
is null. We have the logic to help the user to fill in a non-zero value
for the RTTI field when such an object is filled from the host. However,
when there is slang code creating an existential value, we still have
old logic in the compiler that just fills in 0 for the RTTI field,
causing an `Optional<IFoo>.hasValue` to always return false in such
cases.Make interface types non c-style in Slang2026. (#7260)2025-06-04T20:05:58+00:00Yong Heyonghe@outlook.com2025-06-04T20:05:58+00:00urn:sha1:812e478989e27983b8dea7ab11964de751654ba2
