2009-06-14sh: Tidy up duplication in irq/swab/timex.h.Paul Mundt
The asm-generic versions have some helper definitions that we can use instead, drop our definitions and use those instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-10sh: Fix up R0 dependence in __arch_swab16/32.Paul Mundt
There is nothing in these routines that inherently depends on R0 use. Given that these routines are inlined, it is rather easy to blow up the compiler by exhausting the spill class when performing a 64-bit swab. This presently manifests itself as the following: CC fs/ocfs2/suballoc.o fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits': fs/ocfs2/suballoc.c:638: error: unrecognizable insn: (insn 2793 1230 1231 103 arch/sh/include/asm/swab.h:33 (set (reg:HI 853) (subreg:HI (reg:SI 149 macl) 2)) -1 (expr_list:REG_DEAD (reg:SI 149 macl) (nil))) fs/ocfs2/suballoc.c:638: internal compiler error: in extract_insn, at recog.c:1991 This patch switches over to using an arbitrarily assigned register instead. While the same issue does not exist in the SH-5 case, there is likewise no harm in having an alternate register used for the byterev/shari pair. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
