commit r17-4683-gc94dbb388de5ecb06f61ad3972eaff4d77933f81 Author: Jose E. Marchesi <[email protected]> Date: Sun Sep 27 09:59:16 2026 +0200 a68: do not generate TYPE_DECLs with null DECL_NAMEs This code in a68-low-moids.cc was leading to struct and union types being emitted with TYPE_DECLs in their TYPE_NAMEs having null DECL_NAMEs, which is a no-no. Algol 68 struct and union modes are always anonymous, until they are given names in a mode declaration. Signed-of-by: Jose E. Marchesi <[email protected]> gcc/algol68/ChangeLog * a68-low-moids.cc (build_stub_type_decl): Remove function. (lower_struct_mode): Do not call build_stub_type_decl. (lower_union_mode): Likewise.
