commit db922eaf0d7df3b917b6b693081219ca6065ec9e
Author: Zack Weinberg <zackw@panix.com>
Date: Wed Dec 27 12:56:04 2017 -0500
Fix problems found by build-many-glibcs.
Most of these have something to do with either old stdio or ldbl-opt.
The changes surrounding PLT bypass for ldbl-affected symbols are a bit
of a bodge but at least they seem to preserve the ABI expectations.
* include/libc-symbols.h (hidden_weak_ver, libc_hidden_weak_ver):
New macros.
* sysdeps/generic/math_ldbl_opt.h (ldbl_hidden_weak): New macro.
* sysdeps/ieee754/ldbl-opt/math_ldbl_opt.h: Also add it.
* libio/iovsprintf.c: Use ldbl_hidden_weak to define vsprintf.
* libio/iovsscanf.c: Use ldbl_hidden_weak to define __vsscanf.
* libio/vasprintf.c: Use strong_alias + ldbl_hidden_def to define
__vasprintf.
* libio/vsnprintf.c: Use ldbl_hidden_weak to define __vsnprintf.
* libio/iolibio.h: Add a multiple inclusion guard. Use FILE
instead of _IO_FILE, __fpos_t instead of _IO_fpos_t, __fpos64_t
instead of _IO_fpos64_t, size_t instead of _IO_size_t, BUFSIZ
instead of _IO_BUFSIZ, and __gnuc_va_list instead of _IO_va_list.
Move the definitions of _IO_pos_BAD, _IO_fileno, _IO_clearerr,
_IO_fseek, and _IO_rewind...
* libio/libioP.h: ...here.
* conform/data/stdio.h-data: Use __gnuc_va_list instead of _G_va_list.
* sysdeps/ieee754/ldbl-opt/nldbl-compat.c: Include libioP.h.
* sysdeps/ieee754/ldbl-opt/nldbl-compat.h: Use va_list instead
of _G_va_list. Declare __nldbl__IO_vfscanf by hand.
* sysdeps/ieee754/ldbl-opt/nldbl-iovfscanf.c: Use __gnuc_va_list
instead of _IO_va_list.
