commit r15-8464-g56145ae79b89b823f306c2c241f6a1fe5d604816
Author: Richard Biener <rguent...@suse.de>
Date: Wed Mar 19 15:02:23 2025 +0100
Make function_decl_type a scoped enum
The enum currently has a member named NONE which pollutes the global
namespace unnecessarily. Use a scoped enum instead.
gcc/
* tree-core.h (function_decl_type): Make a scoped enum.
* tree.h (set_function_decl_type): Adjust.
(DECL_IS_OPERATOR_NEW_P): Likewise.
(DECL_SET_IS_OPERATOR_NEW): Likewise.
(DECL_IS_OPERATOR_DELETE_P): Likewise.
(DECL_SET_IS_OPERATOR_DELETE): Likewise.
(DECL_LAMBDA_FUNCTION_P): Likewise.
(DECL_SET_LAMBDA_FUNCTION): Likewise.
* lto-streamer-out.cc (hash_tree): Hash all of
FUNCTION_DECL_DECL_TYPE.
* tree-streamer-out.cc (pack_ts_function_decl_value_fields):
Adjust.
* config/aarch64/aarch64-simd-pragma-builtins.def (vcombine_mf8):
Use literal zero instead of NONE.
gcc/cp/
* module.cc (trees_out::core_bools): Convert scoped enum
explicitly.
