* Detect and select i586/i686 implementation at run-time fedora/masterH.J. Lu2015-08-277-3/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We detect i586 and i686 features at run-time by checking CX8 and CMOV CPUID features bits. We can use these information to select the best implementation in ix86 multiarch. HAS_I586/HAS_I686 is true if i586/i686 instructions are available on the processor. Due to the reordering and the other nifty extensions in i686, it is not really good to use heavily i586 optimized code on an i686. It's better to use i486 code if it isn't an i586. USE_I586/USE_I686 is true if i586/i686 implementation should be used for the processor. USE_I586 is true only if i686 instructions aren't available. If i686 instructions are available, we always choose i686 or i486 implementation, in that order, and we never choose i586 implementation for i686-class processors. * sysdeps/i386/init-arch.h: New file. * sysdeps/i386/i586/init-arch.h: Likewise. * sysdeps/i386/i686/init-arch.h: Likewise. * sysdeps/x86/cpu-features.c (init_cpu_features): Set bit_I586 bit if CX8 is available.

| | | | | | | | | | | | | | Linux commit b4b56f9ecab40f3b4ef53e130c9f6663be491894 introduced a new HWCAP2 bit to indicate that the kernel now aborts a memory transaction when a syscall is made.

* Adjust _Unwind_Word in unwind.h to version in libgcc.Stefan Liebler2015-08-262-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building glibc on s390-32 with gcc option -mzarch produces the error due to sysdeps/s390/jmpbuf-unwind.h:37:10: (void *) (_Unwind_GetCFA (_context): cast to pointer from integer of different size [-Werror=int-to-pointer-cast] Building on s390-32 in esa-mode or s390-64 is fine. _Unwind_GetCFA returns an _Unwind_Word which is an unsigned with a size of 4 bytes on s390-32 (esa-mode) and 8 bytes on s390-64. On s390-32 (zarch-mode), _Unwind_Word has a size of 8 bytes, too. _Unwind_Word is defined in sysdeps/generic/unwind.h as typedef unsigned _Unwind_Word __attribute__((__mode__(__word__))); In libgcc unwind header (<gcc-src>/libgcc/unwind-generic.h) this typedef has changed to "typedef unsigned _Unwind_Word __attribute__((__mode__(__unwind_word__)));" in June 2008. With this mode, _Unwind_Word has a size of 4 bytes on s390-32 (zarch-mode). The same change applies to _Unwind_Sword. Thus this patch updates the unwind header according to these changes. Afterwards, the int-to-pointer-cast-warning is gone away on s390-32 (zarch-mode) and the testsuite runs with the same test-failures as s390-32 (esa-mode) plus FAIL: c++-types-check. Here register_t is expected to has a size of 4 bytes, but it has a size of 8 bytes due to: posix/sys/types.h:205:typedef int register_t __attribute__ ((__mode__ (__word__))); The libgcc-patch for gcc 4.4 can be found here: "[PATCH, spu, unwind] Remove attribute ((mode (word))) from unwind.h" https://gcc.gnu.org/ml/gcc-patches/2008-06/msg00969.html ChangeLog: * sysdeps/generic/unwind.h (_Unwind_Word): Use __mode__(__unwind_word__) instead of __mode__(__word__).

* S390: Fix build error with gcc6 in utf8_utf16-z9.c.Stefan Liebler2015-08-262-0/+8
| | | | | | | | | | | | | | | | | | This patch fixes the build error with gcc6: array subscript is above array bounds [-Werror=array-bounds] While including loop.c to construct the SINGLE(LOOPFCT) method for converting from UTF-16 to UTF-8, the bytebuf array with length MAX_NEEDED_INPUT is used as inptr. MAX_NEEDED_INPUT defaults to MIN_NEEDED_INPUT if not defined before including loop.c. Thus bytebuf has a length of 2. This patch defines MAX_NEEDED_INPUT to MAX_NEEDED_TO, which is 4. ChangeLog: * sysdeps/s390/s390-64/utf8-utf16-z9.c (MAX_NEEDED_INPUT): New define. (MAX_NEEDED_OUTPUT): New define.
* S390: Optimize string, wcsmbs and memory functions.Stefan Liebler2015-08-262-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch set introduces optimized string, wcsmbs and memory functions for S390/S390x. The functions are accelerated by the usage of the new z13 vector instructions. The Principles of Operations manual for IBM z13 is publically available: http://publibfi.boulder.ibm.com/epubs/pdf/dz9zr010.pdf The support for these instructions in assembler was introduced by commits: -"[Committed] S/390: Add support for IBM z13." (https://sourceware.org/ml/binutils/2015-01/msg00197.html) -"[Committed] S/390: Add more IBM z13 instructions" (https://sourceware.org/ml/binutils/2015-03/msg00088.html) The first patches do preparation for the latter optimization patches. The floating point exception handling - fetestexcept(), ... - is fixed and the platform and hwcap strings are extended. The current ifunc routines memset, memcpy and memcmp are refactored and the ifunc test-framework is now enabled. A S390 specific configure-check tests if the used binutils supports the new vector instructions. The optimized functions are provided via ifunc if the binutils supports the vector instructions. Otherwise a message is dumped to configure output and only the currently used common code functions are available. The optimized functions are implemented in common for s390-32 and s390-64 and the few differences are handled via #ifdef. The ifunc-resolvers are defined in files sysdeps/s390/multiarch/<func>.c, which choose either the current implementation __<func>_c() or the vector implementation __<func>_vx() depending on the HWCAP_S390_VX flag bit in AT_HWCAP field. If the bit is set, the hardware and the kernel are supporting vector registers and instructions. If the used binutils lacks vector-support, then the default implementation in string or wcsmbs directory is included here instead. The file sysdeps/s390/multiarch/<func>-c.c includes the current implementation and defines the function name __<func>_c. The assembler files sysdeps/s390/multiarch/<func>-vx.S with the vector instructions are using the directive '.machine "z13"' to allow building glibc without option '-march=z13'. Additionally the directive '.machinemode "zarch_nohighgprs"' is needed for the 31bit glibc. This mode does not set the highgprs flag in ELF header, which would lead to an unloadable libc on a 31bit kernel. The most optimized string functions are structured in the same way: The first 16 bytes of the string is loaded unaligned via vlbb - vector load to block boundary (e.g. 4k). This instruction loads 16 bytes if possible. In case of a page cross, it only loads the last bytes of the current page without a segmentation fault. Afterwards these first part of string is processed. If e.g. for strlen the end of string is reached within this first part, the function returns. Otherwise the pointer is aligned to 16 byte, so i can load a full vector register with vl without checking for a page cross. Afterwards the first part of string is processed. If e.g. for strlen the end of string is reached within this first part, the function returns. Otherwise the pointer is aligned to 16 byte, so a full vector register can be loaded with vl - vector load - without checking for a page cross. The remaining string is processed in a four times unrolled loop, because benchmark results measured improvements compared to a non unrolled loop. The optimized wide string functions can only handle 4byte aligned string pointers. Although a wchar_t pointer should always be 4byte aligned, the most current common code wide string functions can handle non aligned strings. Thus the optimized functions will fall back to the common code functions in case of a non aligned wide string to behave the same as before this patch. Some string tests can test the string and the wide string version of a function. The remaining ones are extended and new wide string tests are added. This is the same in case of the benchtests.

| | | | | | | | | | | This patch introduces a s390 specific ifunc resolver macro for 32/64bit, which chooses <func>_vx with vector instructions if HWCAP_S390_VX flag in hwcaps is set or <func>_c if not.

* S390: configure check for vector instruction support in assembler.Stefan Liebler2015-08-264-0/+80
| | | | | | | | | | | | | | | | | | | | | | The S390 specific test checks if the assembler has support for the new z13 vector instructions by compiling a vector instruction. The .machine and .machinemode directives are needed to compile the vector instruction without -march=z13 option on 31/64 bit. On success the macro HAVE_S390_VX_ASM_SUPPORT is defined. This macro is used to determine if the optimized functions can be build without compile errors. If the used assembler lacks vector support, then a warning is dumped while configuring and only the common code functions are build. The z13 instruction support was introduced in "[Committed] S/390: Add support for IBM z13." (https://sourceware.org/ml/binutils/2015-01/msg00197.html) ChangeLog: * config.h.in (HAVE_S390_VX_ASM_SUPPORT): New macro undefine. * sysdeps/s390/configure.ac: Add test for S390 vector instruction assembler support. * sysdeps/s390/configure: Regenerated.
* S390: Add new s390 platform.Stefan Liebler2015-08-263-3/+8
| | | | | | | | | | | | The new IBM z13 is added to platform string array. The macro _DL_PLATFORMS_COUNT is incremented to 8, because it was not incremented by commit "S/390: Sync AUXV capabilities and archs with kernel". ChangeLog: * sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags): Add z13. * sysdeps/s390/dl-procinfo.h (_DL_PLATFORMS_COUNT): Increased.
