Bug ID: 113694
Summary: Allow renaming stack smashing protector symbols
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: matheus.a.m.moreira at gmail dot com
Target Milestone: ---
I'm writing freestanding Linux applications which are compiled with
-ffreestanding -nostdlib. In order to integrate with the stack smashing
protector, I need to provide the following symbols:
__stack_chk_guard
__stack_chk_fail
It would be nice if there was a compiler option to rename these symbols to
something else. I want to make them consistent with the rest of my code,
thereby improving its quality.
A couple of options would be enough:
-fstack-protector-canary=my_variable
-fstack-protector-handler=my_function
Attributes could work too:
uintptr_t my_canary __attribute__((stack_protector_canary));
__attribute__((noreturn, stack_protector_handler))
void __stack_chk_fail(void);=
