* tls.m4 (GCC_CHECK_CC_TLS): New.
libgcc/
2007-07-06 H.J. Lu <hongjiu.lu@intel.com>
* config.host (tmake_file): Add t-tls for i[34567]86-*-linux*
and x86_64-*-linux*.
* config/t-tls: New file.
* Makefile.in (INTERNAL_CFLAGS): Add @set_have_cc_tls@.
* configure.ac: Include ../config/enable.m4 and
../config/tls.m4. Use GCC_CHECK_CC_TLS to check if assembler
supports TLS and substitute set_have_cc_tls.
* configure: Regenerated.
libbid/
2007-07-06 H.J. Lu <hongjiu.lu@intel.com>
Updated from Intel BID library:
* bid_conf.h (BID_THREAD): Defined only if both HAVE_CC_TLS
and USE_TLS are defined.
