* sh: plug vsyscall dir in to archclean.Paul Mundt2009-06-101-0/+1
| | | | | | | | The vsyscall targets are presently not cleaned up, so just handle it in the archclean rule. Reported-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Hook up cc-cross-prefix support.Paul Mundt2009-05-101-0/+6
| | | | | | | This implements a simple case that just iterates through the common cases, looking at UTS_MACHINE for hints. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Provide a BITS definition, use it in the arch/sh/boot/ Makefiles.Paul Mundt2009-05-101-4/+4
| | | | | | | | This introduces a BITS export that can handily be picked up by Makefiles for cleaner sharing. Reflect its use in arch/sh/boot/compressed/ in preparation for unifying the Makefiles. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Tidy up the ldscript output format specifier.Paul Mundt2009-05-101-2/+6
| | | | | | | | Tie this in to the Makefile directly, where we already know what we are running on. This tidies up the linker script a bit, and is prep work for unifying the arch/sh/boot/compressed linker scripts. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off extra cflags Kconfig entry.Paul Mundt2009-05-081-3/+0
| | | | | | | There is no real reason to use this anymore, as the build system generally knows what it is doing with regards to cflags mangling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Provide sdivsi3/udivsi3/udivdi3 for sh64, kill off libgcc linking.Paul Mundt2008-12-221-3/+1
| | | | | | | This moves in the necessary libgcc bits and kills off the libgcc linking for sh64 kernels as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Consolidate rsk7203/7201 in to a new mach-rsk.Paul Mundt2008-12-221-0/+1
| | | | | | | RSK+ platforms have quite a few characteristics in common, so roll them together in to a shiny new RSK mach-type. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Re-add support for best fit ISA tuning if none is available.Paul Mundt2008-12-221-5/+20
| | | | | | | | | | | This was removed in the libgcc integration, but there are still some compilers that need this. We also relax the rules on the ISA tuning in the cases where there are no matches for the CPU tuning and adopt the -any default, which matches the intent of the isa-y target list. This compensates for mismatches where binutils supports a wide array of targets whilst the compiler is much more restricted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Migrate necessary libgcc bits in to arch/sh/lib for SUPERH32.Paul Mundt2008-12-221-18/+1
| | | | | | | | 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: SHmedia ISA tuning fixups.Paul Mundt2008-10-311-0/+4
| | | | | | | SH-5 doesn't support any elaborate ISA inheritance schemes (-dsp, -up, etc.), so only bother with that if we are building an sh32 kernel. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Simplify and lock down the ISA tuning.Paul Mundt2008-10-281-9/+1
| | | | | | | | | | | | | | | | | | | The ISA tuning as it is today can not cope with all of the different variations that are possible, so all we can do is a best attempt based on the CPU family. The DSP and FPU generation are already at odds with each other, and the nommu tuning we weren't handling at all. Additionally, for platforms that never had an FPU, the -nofpu variant never existed, meaning that we would lose out on family granular tuning completely in certain cases. With tat out of the way, we were also using -up versions, allowing for later instructions that branched off of a particular subset of the ISA, but are not actually reflected on the hardware being targetted. This leads to some confusion, and the possibility of bogus instructions on older parts. Kill that off and lock it down to the family being built for specifically.

* sh: Fix FPU tuning on toolchains with mismatched multilib targets.Paul Mundt2008-10-281-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently there is very little standing in the way of using an SH-4 toolchain for building an SH-2 kernel, and vice versa. Binutils itself has no limitations whatsoever and supports explicit ISA hinting, which we already use with varying degrees of success today. This leaves GCC as the odd one out, due to a rather dubious policy decision by the GCC folks to not include all of the CPU family variants in the default list of multilib targets in GCC4. Despite best efforts to the contrary, libgcc itself already contains awareness of the various CPU types and remains generally usable, allowing it to safely be referenced even on a mismatched target (and indeed, explicit ISA tuning by binutils keeps us honest in terms of ensuring that we do not link incompatible objects in). In order to support this, a couple of changes had to be made. Firstly, the introduction of MAYBE_DECLARE_EXPORT(), which provides a __weak extern reference for libgcc resident routines when finer-grained -m<cpu-family> based tuning is not supported by the toolchain. This fixes up the __sdivsi3_i4i and __udivsi3_i4i references when dealing with SH-2 kernels linked with an SH-4 libgcc. Secondly, in case where we are unable to find a suitable match for CPU family tuning but still have a toolchain that defaults to FP instruction generation, a suitable nofpu target must be selected. This is accomplished by selecting the first nofpu multilib target supported by the toolchain, which is also necessary for selecting the proper libgcc to link against.
