From: "fw at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug libgcc/113403] New: __builtin_nested_func_ptr_created, __builtin_nested_func_ptr should be dynamically linked by default Date: Mon, 15 Jan 2024 16:42:29 +0000 [thread overview] Message-ID: <bug-113403-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113403 Bug ID: 113403 Summary: __builtin_nested_func_ptr_created, __builtin_nested_func_ptr should be dynamically linked by default Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libgcc Assignee: unassigned at gcc dot gnu.org Reporter: fw at gcc dot gnu.org Target Milestone: --- There are hidden definitions of __builtin_nested_func_ptr_created, __builtin_nested_func_ptr in libgcc.a. As a result of the default link order, the exported global definitions of these functions in libgcc_s.so.1 are never used. This is unfortunate because it means that every DSO that creates a trampoline gets its own trampoline cache (one TLS variable and two data pages for trampolines), increasing the overhead of this feature significantly.
