Bug 15251 – [REG2.069.0-rc1] std.datetime bug with -inline

Created attachment 1559 Minimized test case The attached code doesn't work with 2.069rc1. It works with beta. It says: Error: cannot cast cast(ubyte)20u to void at compile time

Sorry, wrong window

Inlining had introduced `cast(void)` expression to `ForStatement.increment` part, then it had hit following interpret issues. 1. `CastExp.interpret` does not work for `cast(void)` if `goal` is not `ctfeNeedNothing`. 2. `ForStatement.interpert` does not evaluate its `increment` part with `ctfeNeedNothing`. I fix both of them for the best work, although fixing one of them can fix the original issue, https://github.com/D-Programming-Language/dmd/commit/1b21ea36893838e30e6b861b4e9000a276cad5d6 Merge pull request #5235 from 9rnsr/fix15251 [REG2.069.0-rc1] Issue 15251 - std.datetime bug with -inline
