* guard *_chk() related stuff with UCLIBC_HAS_FORTIFYPeter S. Mazinger2011-03-092-7/+3
| | | | | | | | | | | | Guard x86_64 memset_chk/memcpy_chk be guarded by UCLIBC_HAS_FORTIFY. Compile ssp.c if one of SSP/FORTIFY is defined. Guard __chk_fail() with UCLIBC_HAS_FORTIFY and move its prototype to libc-internal.h. Disable _FORTIFY_SOURCE if UCLIBC_HAS_FORTIFY is not set. The config option itself is omitted on purpose, headers need to be reviewed and generic *_chk() functions need to be first provided. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net>

* sh: fix memcpy saving/restoring FR12-FR15 registersGiuseppe Cavallaro2010-12-141-3/+15
| | | | | | | | | | | | This patch fixes a bug in the memcpy that doesn't save/restore the FR12-FR15 registers (callee save registers in ST40 ABI) while copying many cache lines with FPU in single paired precision mode and by using all FPU registers (DR and XD).

* sh: update the memcpy adding a new loop with aggressive prefetchingSalvatore Cro2010-09-151-21/+107
| | | | | | | | | | | | | | | | After exploring different prefetch distance-degree combinations in this new update of the memcpy function, a new loop has been added for moving many cache lines with an aggressive prefetching schema. Prefetch has been removed when move few cache line aligned blocks. As final result, this memcpy gives us the same performances for small sizes (we already had!) and better numbers for big copies. In case of SH4-300 CPU Series, benchmarks show a gain of ~20% for sizes from 4KiB to 256KiB. In case of the SH4-200, there is a gain of ~40% for sizes bigger than 32KiB.

* sh: move data without fetching cache block within the memsetSalvatore Cro2010-09-151-28/+34
| | | | | | | | | | | | | | | | | | | | | | | With this patch the movca.l instruction is used within the memset. The current memset implementation only uses the FPU and there is an real gain for all the sizes. Adding the movca.l instruction numbers always are better than the generic code. There is a big gain for size greater than 64 KiB but number are worst for 4-32KiB sizes compared with the implementation without movca.l.
