commit 3020f72618
Author: Adhemerval Zanella Netto <adhemerval.zanella@linaro.org>
Date: Tue Dec 27 18:11:43 2022 -0300
libio: Remove the usage of __libc_IO_vtables
added
#define libio_static_fn_required(name) __asm (".globl " #name);
to link in libio functions in static binaries. But there is no relocation
in
.globl _IO_file_open
and "strip --strip-unneeded" will remove such unreferenced symbols which
breaks static binaries. Redefine libio_static_fn_required to create a
reference to the required function with
static __typeof (name) *const name##_p __attribute__((used)) = name;
This fixes BZ #33300.
