* malloc: handle size overflows in realloc()Mike Frysinger2009-10-161-0/+3
| | | | | | | | | | The malloc() code checks the incoming size to make sure the header adjustment doesn't cause overflow in the size storage. Add the same check to realloc() to catch stupid stuff like realloc(..., -1).

* sparc qops: unify & shrinkMike Frysinger2009-10-161-51/+40
| | | | | | | | | | We don't really need to know the exact symbol that caused a failure as long as we know where to start looking. So unify the duplicate code between all funcs and between the sparc variants. This gives us a nice code shrink of ~95%.

* sh: Align sh clone implementation with glibcCarmelo Amoroso2009-10-101-8/+7
| | | | | | | | | Align sh clone implementation with glibc one that incorporated time ago a patch provided by me slightly modified. The glibc code indeed avoids to load the r3 register if the 2nd function argument is NULL (r5). No functional change. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

* Fix building arm EABIBernhard Reutner-Fischer2009-10-082-1/+2

* sh: Add new optimisation to the SH4 memcpyGiuseppe Cavallaro2009-09-271-2/+107
| | | | | | | | | | | | | | | | | | This optimization is based on prefetching and 64bit data transfer via FPU (only for the little endianess) Tests shows that: ---------------------------------------- Memory bandwidth | Gain | sh4-300 | sh4-200 ---------------------------------------- 512 bytes to 16KiB | ~20% | ~25% from 32KiB to 16MiB | ~190% | ~5% ---------------------------------------- Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* sh: add assembly strcpy and strncpyGiuseppe Cavallaro2009-09-272-0/+71
| | | | | | | | | | | | | | | | | This patch adds the strcpy and strncpy assembly routines. Benchmarks showed the following gains: ~7% for strcpy ~30% for strncpy Note: uClibc string tests pass without any failures. These functions have been only tested on SH4, for this reason I've voluntarily added them within the sh4 sub-folder. If somebody would like to test them on other SH CPUs, these can be moved on sh common folder.

* sh: add a new memmove optimised for SH4Giuseppe Cavallaro2009-09-271-0/+119
| | | | | | | | | | | | | | | This patch adds the memmove fuction for SH4. By default, it used the generic implementation. This new code uses the memcpy for BWD copies and implements FWD copy when required (see comment within the code itself). The idea behind is to get advantage of using the optimised memcpy for SH4 and use the FPU for FWD copies (for big sizes) as well. LMBench bw_mem test showed a significant improvement on uClibc because bcopy invokes memmove, directly.

* sh: add assembly memset from Kernel and optimise it for SH4Giuseppe Cavallaro2009-09-271-0/+146
| | | | | | | | | | | This patch adds the SH memset assembly implementation currenlty included into the Kernel. It also adds, only for little endian mode, the 64bit data transfer via FPU (using single paired precision mode). Tests shows that on SH4-300 we gain ~100% for size greater than 1KiB.

* sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs2009-09-181-0/+11
| | | | | | | | | | | | | This patch makes sufficient modifications to the SH sys/user.h to be able to build and run gdbserver with Linux kernel 2.6.30. The problem is that both the kernel and library headers define the same symbols, thus making it impossible in include both headers. The patch undefines the kernel symbols in favour of the library symbols.

* daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger2009-09-181-4/+6
| | | | | | | | | | | | Make sure we declare the error properly in case a port uses it, and fix the invocation of exit(). Since clone() will be returning a pid, assume that the value will not have the MSB set (negative) to simplify the error test a bit more. If gcc supports it, force this function to always be heavily optimized in a bid to avoid stack usage as much as possible.
