Hello!

2011-05-18  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.md (*tls_global_dynamic_32_gnu): Split asm template.
	(*tls_global_dynamic_64): Ditto.
	(*tls_local_dynamic_base_32_gnu): Ditto.
	(*tls_local_dynamic_base_64): Ditto.
	(tls_initial_exec_64_sun): Ditto.

No functional changes.

Patch was tested on x86_64-pc-linux-gnu {,-m32}, committed to mainline SVN.

Uros.
