Johann	4a2b684ef4	modify SAVE_XMM for potential 64bit use ... the win64 abi requires saving and restoring xmm6:xmm15. currently SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow specifying the highest register used and if the stack is unaligned.

Yunqing Wang	6614563b8f	Save XMM registers in asm functions ... XMM6/7 are used in these functions, and need to be saved. Change-Id: I3dfaddaf2a69cd4bf8e8735c7064b17bac5a14e5	2010-10-28 16:59:03 -04:00
John Koleszar	b523dd51bd	add missing GET_GOT/RESTORE_GOT pairs ... These functions made global references but did not set up the GOT, causing compilation failures in PIC mode. Change-Id: Iac473bf46733f87eb2e001cd736af4acf73fa51d	2010-10-25 23:45:02 -04:00
Yunqing Wang	4cefb4434f	Add MMWORD PTR/XMMWORD PTR in subtract_sse2.asm ... Change-Id: Ia649b500ef020225d8bbf611799d0f47658dc2ac	2010-10-21 13:42:24 -04:00
Yunqing Wang	4db2076594	Add SSE2 subtract functions ... Instead of doing 8-bit data unpack and 16-bit subtraction, use psubb to do 16 8-bit subtractions and pcmpgtb to preserve the sign information. This does not bring noticable gain since these functions are not called frequently. Change-Id: I90a0dfaa3db9d422e4ada324076596ffb178548e	2010-10-18 14:15:15 -04:00
