* sh: always link in helper functions extracted from libgccGeert Uytterhoeven2013-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | E.g. landisk_defconfig, which has CONFIG_NTFS_FS=m: ERROR: "__ashrdi3" [fs/ntfs/ntfs.ko] undefined! For "lib-y", if no symbols in a compilation unit are referenced by other units, the compilation unit will not be included in vmlinux. This breaks modules that do reference those symbols. Use "obj-y" instead to fix this. http://kisskb.ellerman.id.au/kisskb/buildresult/8838077/ This doesn't fix all cases. There are others, e.g. udivsi3. This is also not limited to sh, many architectures handle this in the same way. A simple solution is to unconditionally include all helper functions. A more complex solution is to make the choice of "lib-y" or "obj-y" depend on CONFIG_MODULES: obj-$(CONFIG_MODULES) += ... lib-y($CONFIG_MODULES) += ...

* sh: Decouple mcount from ftrace.Paul Mundt2009-07-11
| | | | | | | | | This adds a general CONFIG_MCOUNT in order to permit mcount generation without ftrace support. This is primarily for allowing platforms to enable aggressive stack overflow checking without having to enable ftrace support. Based on the sparc64 implementation.

* sh: Add plain udivsi3 (not _i4*) for gcc-4.1 and lower.Takashi YOSHII2008-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We chan't share code for udivsi3 and udivsi3_i4, because they have a different clobber list. Copy udivsi3 from gcc-4.1.2. As shown in arch/sh/lib/udivsi3.S (and -Os.S), .global __udivsi3_i4i .global __udivsi3_i4 .global __udivsi3 __udivsi3_i4i: ... Three symbols are sharing one code, which is actually udivsi3_i4i. But, this results unwanted code with gcc 4.1. In gcc, these three are treated as pseudo instructions that have their own clobber list apart from the usual calling convention. According to sh's machine description. The clobber list is as follows: - udivsi3_i4i : t,r1,pr,mach,macl - udivsi3_i4 : t,r0,r1,r4,r5,pr,dr0,dr2,dr4 - udivsi3 : t,r4,pr The caller of udivsi3 will be left with a broken r1 and mac*. gcc-4.1.x and older(at least to 3.4) generate udivsi3. ST's gcc-4.1.1 seems to be OK because it has _i4i. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Migrate necessary libgcc bits in to arch/sh/lib for SUPERH32.Paul Mundt2008-12-22
| | | | | | | | This moves in the necessary libgcc bits for SUPERH32 and drops the libgcc linking for the regular targets. This in turn allows us to rip out quite a few hacks both in sh_ksyms_32 and arch/sh/Makefile. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Kill off udivdi3 div64_32 wrapping.Paul Mundt2007-05-06
| | | | | | | | | | | | | Previously we've been handling udivdi3 references and wrapping them in to div64_32() automatically. This doesn't get a lot of use, however, and as akpm noted in the recent thread on l-k: http://lkml.org/lkml/2007/2/27/241 we're better off simply ripping it out and going the do_div() route if there happen to be any places that need it.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
