• bump VERSION to v2.092.0-rc.1
• Revert "Fix Issues 20718, 15867, 12380 - Wrong location errors on const. folding / exp. optimization"
• Fix Issue 20795 - [dip1000] segfault on templated opEquals
• [squash] Move state to Target (where it can be reset via Target.deinitialize())
• Prevent redundant type semantic for va_list
• Fix issue 20779: compiler segfaults when struct contains itself When working with metaprogramming, the error message saying that the struct should not contain itself can get swallowed by gagging. In this case, only the segfault remains, leading to an unsatisfactory user experience. Fix the segfault by breaking the infinite recursion.
• [stable] dmd.dsymbolsem: Fix va_list check for pragma([printf,scanf]) ([stable] dmd.dsymbolsem: Fix va_list check for pragma([printf,scanf]) #11068)
• Add dmd.argtypes_aarch64 for the AAPCS64 ABI
• Introduce TypeTuple.empty global to prevent creating lots of empty TypeTuples
• Replace StructDeclaration.arg{1,2}type by a .argTypes TypeTuple
• dmd.root.filename: Restore C++ absolute() / ext() versions
• Fix C++ header regressions
