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.
