Make various error-related globals thread-local
This changes bfd_error et al to be thread-local. * Makefile.in: Regenerate. * aclocal.m4: Include ax_tls.m4. * ax_tls.m4: New file. * bfd.c: (bfd_error, input_error, input_bfd, _bfd_error_buf): Now thread-local. (bfd_asprintf): Update docs. * config.in, configure: Regenerate. * configure.ac: Call AX_TLS. * po/bfd.pot: Regenerate.

# SYNOPSIS

#
|
||||
# AX_TLS([action-if-found], [action-if-not-found])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# Provides a test for the compiler support of thread local storage (TLS)
|
||||
# extensions. Defines TLS if it is found. Currently knows about C++11,
|
||||
# GCC/ICC, and MSVC. I think SunPro uses the same as GCC, and Borland
|
||||
# apparently supports either.

|
||||
Primarily for error reporting, this function is like
|
||||
libiberty's xasprintf except that it can return NULL on no
|
||||
memory and the returned string should not be freed. Uses a
|
||||
single malloc'd buffer managed by libbfd, _bfd_error_buf.
|
||||
thread-local malloc'd buffer managed by libbfd, _bfd_error_buf.
|
||||
Be aware that a call to this function frees the result of any
|
||||
previous call. bfd_errmsg (bfd_error_on_input) also calls
|
||||
this function.
