From b8702dfb6d0e41515fa0f9f899d86b7935dfc3fd Mon Sep 17 00:00:00 2001 From: Yong He Date: Tue, 25 Aug 2020 21:55:05 -0700 Subject: Export witness table and RTTI objects in compiled libraries. (#1514) * Export witness table objects in compiled code. - Ensure that witness tables are preceeded with `extern "C"` modifier in the generated C++ code. - RTTI objects use the mangled name of the type directly, so that can be queried using the type's mangled name directly from the resulting DLL. - Expose `Linkage::getTypeConformanceWitnessMangledName` to return the mangled name of witness tables to the host. - Ensure that all witness tables (including those for associated types) have proper mangled name. * Fix GCC error in Slang generated code. --- source/slang/slang-check-decl.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'source/slang/slang-check-decl.cpp') diff --git a/source/slang/slang-check-decl.cpp b/source/slang/slang-check-decl.cpp index f9a514d23..4fa5fff17 100644 --- a/source/slang/slang-check-decl.cpp +++ b/source/slang/slang-check-decl.cpp @@ -2450,6 +2450,7 @@ namespace Slang { witnessTable = new WitnessTable(); witnessTable->baseType = DeclRefType::create(m_astBuilder, interfaceDeclRef); + witnessTable->witnessedType = type; } context->mapInterfaceToWitnessTable.Add(interfaceDeclRef, witnessTable); @@ -3021,6 +3022,7 @@ namespace Slang // RefPtr witnessTable = new WitnessTable(); witnessTable->baseType = enumConformanceDecl->base.type; + witnessTable->witnessedType = enumTypeType; enumConformanceDecl->witnessTable = witnessTable; Name* tagAssociatedTypeName = getSession()->getNameObj("__Tag"); -- cgit v1.2.3
