| | | | | | | | * elf/elf.h (R_SPARC_WDISP10): Define. * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Handle R_SPARC_SIZE32. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Handle R_SPARC_SIZE64 and R_SPARC_H34.

* Reduce down to one definition of _ELF_DYNAMIC_DO_RELOC.David S. Miller2012-04-054-13/+0
| | | | | | | | | | | | | * elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): Reduce down to one definition. * sysdeps/powerpc/powerpc32/dl-machine.h (ELF_MACHINE_PLTREL_OVERLAP): Delete. * sysdeps/s390/s390-32/dl-machine.h (ELF_MACHINE_PLTREL_OVERLAP): Likewise. * sysdeps/sparc/sparc32/dl-machine.h (ELF_MACHINE_PLTREL_OVERLAP): Likewise. * sysdeps/sparc/sparc64/dl-machine.h (ELF_MACHINE_PLTREL_OVERLAP): Likewise.
* Fix size parameter comparisions.Michael Matz2012-04-051-6/+6
| | | | | | | | | | | | | [BZ #13592] There are several signed compares of the size argument, whereas it really is unsigned. Depending on situations e.g. a "memset(ptr, 0, -1)" segfault (but for the wrong reasons, because jumping into nirvana) or succeeds even. In normal use this is harmless, as a size with signbit set indicates more than half the address space which on x86_64 is impossible to allocate, but as the size is used to index some jump tables this potentially could have other unwanted side effects.
* Fix return value of SH fesetround.Kaz Kojima2012-04-051-3/+3

* [BZ #13553] Remove pre-ISO C supportThomas Schwinge2012-04-052-4/+4
| | | | The bits missing from a784e502472fb3a1afa4d01a47c66b52d23e00f6.
* Add __bswap_64 definition for non GCC compilers.Andreas Jaeger2012-04-033-14/+44
| | | | | | | | | [BZ#13926] Currently __bswap_64 is not defined at all for non-GCC compilers. Define it but guard it with __GLIBC_HAVE_LONG_LONG. endian.h uses __bswap_64, make the functions only available if __GLIBC_HAVE_LONG_LONG is defined.
* Call __ctype_init in early glibc startup.Thomas Schwinge2012-04-024-5/+20
| | | | This adds the bits missing from fd5bdc0924e0cfd1688b632068c1b26f3b0c88da.
* optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.SLiubov Dmitrieva2012-03-301-536/+1449
| | | | | | | | | | | | | | I've improved the following implementation of memcpy: "sysdeps/i386/i686/multiarch/memcpy-ssse3.S". The patch includes some minor style fixes, but the important part is just using prefetch loops for the case: DATA_CACHE_SIZE_HALF <= len < SHARED_CACHE_SIZE_HALF and src and dst pointers have unequal 16 byte alignments. This gives from 6% - 50% performance boost on the atom machine, about 24,73% in geometric mean.
