* sparc: check for log double support in gccKonrad Eisele2010-12-271-0/+6
| | | | | | | | | To compile the quad float emulation library gcc needs __LONG_DOUBLE_128__ macro defined. Check first, if not supported then revert to the qp_ops.c stubs Signed-off-by: Konrad Eisele <konrad@gaisler.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>

* 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).

* libc_utmp: Fix getutmp and getutmpx for x86_64Carmelo Amoroso2010-11-281-2/+4
| | | | | | | | | | | | On x86_64, when WORDSIZE_COMPAT32 is enabled, the ut_tv field of 'struct utmp' and 'struct utmpx' are defined as two nested structs instead of being defined as 'struct timeval', so it is not possible to directly assign the two ut_tv values. This patch split the assignment by setting each fields (tv_sec, tv_usec) of the ut_tv filed separately It is als compatible with 'struct timeval' usage.

* mips: fix errno setting after syscallAlexander Gordeev2010-10-271-2/+4
| | | | | | | | | | | | | | | If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

* 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.
