Revision 102fa15c3f14565f2edb9f08f08ea3f2bf123dc9 authored by Ralf Baechle on 16 February 2007, 17:18:50 UTC, committed by Ralf Baechle on 18 February 2007, 21:31:35 UTC
Add R2 optimized variants of clear_bit, set_bit and test_and_clear_bit. With gcc 4.1.1 this saves 1592 bytes on a defconfig (minus IPv6) kernel. Turns out that R2 bitop instructions are no gain for the other bitop functions. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
