Subject: PATCH, v2: PR target/47715: [x32] Use SImode for thread pointer

Hello!

ABI specifies that TP is loaded in ptr_mode. Attached patch implements
this requirement.

2011-07-29  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.md (*load_tp_x32): New.
	(*load_tp_x32_zext): Ditto.
	(*add_tp_x32): Ditto.
	(*add_tp_x32_zext): Ditto.
	(*load_tp_<mode>): Disable for !TARGET_X32 targets.
	(*add_tp_<mode>): Ditto.
	* config/i386/i386.c (get_thread_pointer): Load thread pointer in
	ptr_mode and convert to Pmode if needed.

Testing on x86_64-pc-linux-gnu in progress. H.J., please test this
version on x32.

Uros.
