Bug ID: 277958
Summary: libc: invalid internal linkage on feclearexcept
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: standards
Assignee: [email protected]
Reporter: [email protected]
See https://github.com/llvm/llvm-project/pull/86320 for context
> It seems FreeBSD's libc is not standard compliant.
> /usr/include/fenv.h:266
>
> __fenv_static inline int
> feclearexcept(int __excepts)
>
> and __fenv_static is defined as static. This means feclearexcept has internal linkage.
> This is not allowed by the C standard and C++ modules can't export named declarations
> with internal linkage. So this is probably something to be fixed in FreeBSD.
