d: Fix internal compiler error: Segmentation fault at gimple-expr.cc:88
Because complex types are deprecated in the language, the new way to
expose native complex types is by defining an enum with a basetype of a
library-defined struct that is implicitly treated as-if it is native.
As casts are not implicitly added by the front-end when downcasting from
enum to its underlying type, we must insert an explicit cast during the
code generation pass.
PR d/106623
gcc/d/ChangeLog:
* d-codegen.cc (underlying_complex_expr): New function.
(d_build_call): Handle passing native complex objects as the
library-defined equivalent.
* d-tree.h (underlying_complex_expr): Declare.
* expr.cc (ExprVisitor::visit (DotVarExp *)): Call
underlying_complex_expr instead of build_vconvert.
gcc/testsuite/ChangeLog:
* gdc.dg/torture/pr106623.d: New test.
