* powerpc64: strrchr optimization for power8Rajalakshmi Srinivasaraghavan2017-04-181-0/+464
| | | | | | | P7 code is used for <=32B strings and for > 32B vectorized loops are used. This shows as an average 25% improvement depending on the position of search character. The performance is same for shorter strings. Tested on ppc64 and ppc64le.

* powerpc64: Add POWER8 strnlenWainer dos Santos Moschetta2017-04-051-0/+433
| | | | | | | | | | | | | | | | | | | | | | | | Added strnlen POWER8 otimized for long strings. It delivers same performance as POWER7 implementation for short strings. This takes advantage of reasonably performing unaligned loads and bit permutes to check the first 1-16 bytes until quadword aligned, then checks in 64 bytes strides until unsafe, then 16 bytes, truncating the count if need be. Likewise, the POWER7 code is recycled for less than 32 bytes strings. Tested on ppc64 and ppc64le. * sysdeps/powerpc/powerpc64/multiarch/Makefile (sysdep_routines): Add strnlen-power8. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c (strnlen): Add __strnlen_power8 to list of strnlen functions. * sysdeps/powerpc/powerpc64/multiarch/strnlen-power8.S: New file. * sysdeps/powerpc/powerpc64/multiarch/strnlen.c (__strnlen): Add __strnlen_power8 to ifunc list. * sysdeps/powerpc/powerpc64/power8/strnlen.S: New file.
* powerpc: Improve strcmp performance for shorter stringsRajalakshmi Srinivasaraghavan2017-02-071-22/+8
| | | | | | | | | | For strings >16B and <32B existing algorithm takes more time than default implementation when strings are placed closed to end of page. This is due to byte by byte access for handling page cross. This is improved by following >32B code path where the address is adjusted to aligned memory before doing load doubleword operation instead of loading bytes. Tested on powerpc64 and powerpc64le.

* powerpc64: strchr/strchrnul optimization for power8Rajalakshmi Srinivasaraghavan2016-12-282-0/+391

* powerpc: Fix return code of strcasecmp for unaligned inputsRajalakshmi Srinivasaraghavan2016-07-051-3/+14
| | | | | | | If the input values are unaligned and if there are null characters in the memory before the starting address of the input values, strcasecmp gives incorrect return code. Fixed it by adding mask the bits that are not part of the string.
* powerpc: Add a POWER8-optimized version of sinf()Anton Blanchard2016-06-301-0/+519
| | | | | This uses the implementation of sinf() in sysdeps/x86_64/fpu/s_sinf.S as inspiration.
* powerpc: Add a POWER8-optimized version of expf()Tulio Magno Quites Machado Filho2016-06-301-0/+303
| | | | | | | | This implementation is based on the one already used at sysdeps/x86_64/fpu/e_expf.S. This implementation improves the performance by ~14% on average in synthetic benchmarks at the cost of decreasing accuracy to 1 ULP.
* powerpc: strcasecmp/strncasecmp optmization for power8raji2016-06-142-0/+466
| | | | | | | This implementation utilizes vectors to improve performance compared to current byte by byte implementation for POWER7. The performance improvement is upto 4x. This patch is tested on powerpc64 and powerpc64le.
* powerpc: Fix --disable-multi-arch build on POWER8Tulio Magno Quites Machado Filho2016-06-063-6/+21
| | | | | | Add missing symbols of stpncpy and strcasestr when multi-arch is disabled. Fix memset call from strncpy/stpncpy when multi-arch is disabled.
* powerpc: Fix operand prefixesGabriel F. T. Gomes2016-05-041-4/+4
| | | | | | | | | | | | | | The file sysdeps/powerpc/sysdeps.h defines aliases for condition register operands. E.g.: 'cr7' means condition register 7. On the one hand, this increases readability, as it makes it easier for readers to know whether the operand is a condition register, a general purpose register or an immediate. On the other hand, this permits that condition registers be written as if they were general purpose, and vice-versa, thus reducing the readability of the code. This commit removes some of these unintentional misuses. The changes have no effect on the final code. Checked with objdump.
* powerpc: Zero pad using memset in strncpy/stpncpyGabriel F. T. Gomes2016-04-291-67/+56
| | | | | | | Call __memset_power8 to pad, with zeros, the remaining bytes in the dest string on __strncpy_power8 and __stpncpy_power8. This improves performance when n is larger than the input string, giving ~30% gain for larger strings without impacting much shorter strings.
* powerpc: Add optimized strcspn for P8Paul E. Murphy2016-04-252-11/+54
| | | | | A few minor adjustments to the P8 strspn gives us an almost equally optimized P8 strcspn.
* powerpc: strcasestr optmization for power8Rajalakshmi Srinivasaraghavan2016-04-223-0/+563
| | | | | | This patch optimizes strcasestr function for power >= 8 systems. The average improvement of this optimization is ~40% and compares 16 bytes at a time using vector instructions. This patch is tested on powerpc64 and powerpc64le.
* powerpc: Optimization for strlen for POWER8.Carlos Eduardo Seo2016-04-151-0/+297
| | | | | This implementation takes advantage of vectorization to improve performance of the loop over the current strlen implementation for POWER7.
* powerpc: Add optimized P8 strspnPaul E. Murphy2016-04-071-0/+179
| | | | | | | This utilizes vectors and bitmasks. For small needle, large haystack, the performance improvement is upto 8x. For short strings (0-4B), the cost of computing the bitmask dominates, and is a tad slower.

* PowerPC: Add comments to optimized strncpyGabriel F. T. Gomes2015-10-011-2/+38
| | | | | * sysdeps/powerpc/powerpc64/power8/strncpy.S: Added comments to some assembly instructions.
* PowerPC: Fix operand prefixesGabriel F. T. Gomes2015-10-011-6/+6
| | | | | | | | | | | | | | | | | | | | The file sysdeps/powerpc/sysdeps.h defines aliases for register operands, which add the letter 'r' as a prefix to a register name. E.g.: register 20 can be written as 'r20', instead of '20'. On the one hand, this increases readability, as it makes it easier for readers to know whether the operand is a register or an immediate. On the other hand, this permits that immediate operands be written as if they were registers, and vice-versa, thus reducing the readability of the code. This commit removes some of these unintentional misuses. This commit also increases readability of the code by adding the prefix 'cr' to some uses of the control register. Both changes have no effect on the final code. Checked with objdump. * sysdeps/powerpc/powerpc64/power8/strncpy.S: Remove or add register prefix from operands.
* powerpc: Fix powerpc64 build failure with binutils 2.22Adhemerval Zanella2015-01-241-1/+4
| | | | | | | | | | | | | | GLIBC memset optimization for POWER8 uses the '.machine power8' directive, which is only supported officially on binutils 2.24+. This causes a build failure on older binutils. Since the requirement of .machine power8 is to correctly assembly the 'mtvsrd' instruction and it is already handled by the MTVSRD_V1_R4 macro, there is no really needed of using it. The patch replaces the power8 with power7 for .machine directive. It fixes BZ#17869.
* powerpc: Optimized strncmp for POWER8/PPC64Adhemerval Zanella2015-01-131-0/+323
| | | | | | | | | | This patch adds an optimized POWER8 strncmp. The implementation focus on speeding up unaligned cases follwing the ideas of power8 strcmp. The algorithm first check the initial 16 bytes, then align the first function source and uses unaligned loads on second argument only. Aditional checks for page boundaries are done for unaligned cases (where sources alignment are different).
* powerpc: Optimized strcmp for POWER8/PPC64Adhemerval Zanella2015-01-131-0/+257
| | | | | | | This patch adds an optimized POWER8 strcmp using unaligned accesses. The algorithm first check the initial 16 bytes, then align the first function source and uses unaligned loads on second argument only. Aditional checks for page boundaries are done for unaligned cases
* powerpc: Optimized st{r,p}ncpy for POWER8/PPC64Adhemerval Zanella2015-01-132-0/+444
| | | | | | | | | | | | | This patch adds an optimized POWER8 st{r,p}ncpy using unaligned accesses. It shows 10%-80% improvement over the optimized POWER7 one that uses only aligned accesses, specially on unaligned inputs. The algorithm first read and check 16 bytes (if inputs do not cross a 4K page size). The it realign source to 16-bytes and issue a 16 bytes read and compare loop to speedup null byte checks for large strings. Also, different from POWER7 optimization, the null pad is done inline in the implementation using possible unaligned accesses, instead of realying on a memset call. Special case is added for page cross reads.
* powerpc: Optimized st{r,p}cpy for POWER8/PPC64Adhemerval Zanella2015-01-132-0/+286
| | | | | | | | | | | | This patch adds an optimized POWER8 strcpy using unaligned accesses. For strings up to 16 bytes the implementation first calculate the string size, like strlen, and issues a memcpy. For larger strings, source is first aligned to 16 bytes and then tested over a loop that reads 16 bytes am combine the cmpb results for speedup. Special case is added for page cross reads. It shows 30%-60% improvement over the optimized POWER7 one that uses only aligned accesses.

* powerpc: Fix encoding of POWER8 instructionAdhemerval Zanella2014-11-031-1/+8
| | | | | This patch adds a binary encoding for 'mtvsrd' instruction to avoid build failures when assembler does not support POWER8.
* PowerPC: memset optimization for POWER8/PPC64Adhemerval Zanella2014-09-101-0/+449
| | | | | | | | | | | | | | | | | | | This patch adds an optimized memset implementation for POWER8. For sizes from 0 to 255 bytes, a word/doubleword algorithm similar to POWER7 optimized one is used. For size higher than 255 two strategies are used: 1. If the constant is different than 0, the memory is written with altivec vector instruction; 2. If constant is 0, dbcz instructions are used. The loop is unrolled to clear 512 byte at time. Using vector instructions increases throughput considerable, with a double performance for sizes larger than 1024. The dcbz loops unrolls also shows performance improvement, by doubling throughput for sizes larger than 8192 bytes.
* PowerPC: Fix --disable-multi-arch buildsAdhemerval Zanella2014-04-092-1/+4
| | | | | | | | | | This patch fixes some powerpc32 and powerpc64 builds with --disable-multi-arch option along with different --with-cpu=powerN. It cleanups the Implies directories by removing the multiarch folder for non multiarch config and also fixing two assembly implementations: powerpc64/power7/strncat.S that is calling the wrong strlen; and power8/fpu/s_isnan.S that misses the hidden_def and weak_alias directives.
