* powerpc: Fix ifuncmain6pie failure with GCC 4.9Adhemerval Zanella2015-01-241-1/+3
| | | | | | | | | | | This patch fix the elf/ifuncmain6pie failure when building with GCC 4.9+. For some reason, the compiler removes the branch taken code at resolve_ifunc (sysdeps/powerpc/powerpc64/dl-machine.h) as dead-code and thus the testcase fails because the ifunc resolves branches to an invalid memory location. It fixes by explicit adding a dependency of value based on odp variable to avoid compiler optimization. It fixes BZ#17868.
* powerpc: Fix POWER7/PPC64 performance regression on LEAdhemerval Zanella2015-01-131-588/+282
| | | | | | | | | | | | | | | | | This patch fixes a performance regression on the POWER7/PPC64 memcmp porting for Little Endian. The LE code uses 'ldbrx' instruction to read the memory on byte reversed form, however ISA 2.06 just provide the indexed form which uses a register value as additional index, instead of a fixed value enconded in the instruction. And the port strategy for LE uses r0 index value and update the address value on each compare loop interation. For large compare size values, it adds 8 more instructions plus some more depending of trailing size. This patch fixes it by adding pre-calculate indexes to remove the address update on loops and tailing sizes. For large sizes it shows a considerable gain, with double performance pairing with BE.
* powerpc: Optimized strncmp for POWER8/PPC64Adhemerval Zanella2015-01-135-5/+374
| | | | | | | | | | 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: Optimize POWER7 strcmp trailing checksRajalakshmi Srinivasaraghavan2015-01-131-114/+83
| | | | | | This patch optimized the POWER7 trailing check by avoiding using byte read operations and instead use the doubleword already readed with bitwise operations.
* powerpc: Optimized strcmp for POWER8/PPC64Adhemerval Zanella2015-01-135-3/+306
| | | | | | | 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 Zanella2015-01-138-6/+542
| | | | | | | | | | | | | 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 strncat for POWER7/PPC64Adhemerval Zanella2015-01-133-270/+31
| | | | | | | | | | | With 3eb38795dbbbd816 (Simplify strncat) the generic algorithms uses strlen, strnlen, and memcpy. This is faster than POWER7 current implementation, especially for unaligned strings (where POWER7 code uses byte-byte operations). This patch removes the assembly implementation and uses a multiarch specialization based on default algorithm calling optimized POWER7 symbols.
* powerpc: Optimized strcat for POWER8/PPC64Adhemerval Zanella2015-01-134-4/+40
| | | | | With new optimized strcpy for POWER8, this patch adds an optimized strcat which uses it along with default implementation at strings/.
* powerpc: Optimized st{r,p}cpy for POWER8/PPC64Adhemerval Zanella2015-01-137-3/+377
| | | | | | | | | | | | 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: abort transaction in syscallsAdhemerval Zanella2015-01-121-0/+16
| | | | | | | | | | | Linux kernel powerpc documentation states issuing a syscall inside a transaction is not recommended and may lead to undefined behavior. It also states syscalls does not abort transactoin neither they run in transactional state. To avoid side-effects being visible outside transactions, GLIBC with lock elision enabled will issue a transaction abort instruction just before all syscalls if hardware supports hardware transactions.

* powerpc: POWER7 strcpy optimization for unaligned stringsRajalakshmi Srinivasaraghavan2014-12-311-82/+245
| | | | | | | | | | | | | | | | This patch optimizes strcpy for ppc64/power7 for unaligned source or destination address. The source or destination address is aligned to doubleword and data is shifted based on the alignment and added with the previous loaded data to be written as a doubleword. For each load, cmpb instruction is used for faster null check. The word aligned optimization is also removed, since the new unaligned code path shows better results handling word-aligned strings. More combination of unaligned inputs is also added in benchtest to measure the improvement.The new optimization shows 2 to 80% of performance improvement for longer string though it does not show big difference on string size less than 16 due to additional checks.
* Fix strftime wcschr namespace (bug 17634).Joseph Myers2014-12-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of strftime, a C90 function, ends up bringing in wcschr, which is not a C90 function. Although not a conformance bug (C90 reserves wcs*), this is still contrary to glibc practice of avoiding relying on those reservations; this patch arranges for the internal uses to use __wcschr instead, with wcschr being a weak alias. This is more complicated than some such patches because of the various IFUNC definitions of wcschr (which include code redefining libc_hidden_def in a way that involves creating __GI_wcschr manually and so also needs to create __GI___wcschr after the change of internal uses to use __wcschr). Tested for x86_64 and 32-bit x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 2014-12-10 Joseph Myers <joseph@codesourcery.com> Adhemerval Zanella <azanella@linux.vnet.ibm.com> [BZ #17634] * wcsmbs/wcschr.c [!WCSCHR] (wcschr): Define as __wcschr.

* Don't use INTDEF/INTUSE with _dl_argv (bug 14132).Joseph Myers2014-11-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_argv with rtld_hidden_data_def and rtld_hidden_proto. Some places in .S files that previously used _dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly (there are plenty of existing examples of such direct use of __GI_*). A single place in rtld.c previously used _dl_argv without INTUSE, apparently accidentally, while the rtld_hidden_proto mechanism avoids such accidential omissions. As a consequence, this patch *does* change the contents of stripped ld.so. However, the installed stripped shared libraries are identical to those you get if instead of this patch you change that single _dl_argv use to use INTUSE, without any other changes. Tested for x86_64 (testsuite as well as comparison of installed stripped shared libraries as described above). [BZ #14132] * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto.

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: multiarch bzero cleanup for PPC64Adhemerval Zanella2014-09-1010-91/+15
| | | | | | | | This patch cleanups the multiarch bzero for powerpc64 by remove the multiarch objects and use instead the the memset embedded implementation presented in each multiarch optimization. The code generate is essentially the same, but the TB_TOCLESS (which is not essential).
* Remove unnecessary uses of NOT_IN_libcSiddhesh Poyarekar2014-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a IS_IN_* macro is defined, then NOT_IN_libc is always defined, except obviously for IS_IN_libc. There's no need to check for both.

* PowerPC: Fix gprof entry point for LEAdhemerval Zanella2014-07-301-0/+2
| | | | | This patch fixes the ELFv2 gprof entry point since the ABI does not define function descriptors. It fixes BZ#17213.
* PowerPC: Cleanup powerpc memmoveAdhemerval Zanella2014-07-081-1/+1
| | | | | | | Now that MEMCPY_OK_FOR_FWD_MEMMOVE should be define on memcopy.h there is no need to specialized powerpc memmove implementation. This patch moves the define set to powerpc memcopy and cleanup its definition on powerpc code.
* PowerPC: Fix compiler warningsAdhemerval Zanella2014-07-081-1/+3
| | | | | This patch fixes some compiler due trailing data in #undef directives and due missing prototypes.
* PowerPC: Align power7 memcpy using VSX to quadwordAdhemerval Zanella2014-07-071-18/+4
| | | | | | This patch changes power7 memcpy to use VSX instructions only when memory is aligned to quardword. It is to avoid unaligned kernel traps on non-cacheable memory (for instance, memory-mapped I/O).
* PowerPC: optimized memmove for POWER7/PPC64Adhemerval Zanella2014-07-079-1/+1016
| | | | | | | | | | | This patch adds an optimized memmove optimization for POWER7/powerpc64. Basically the idea is to use the memcpy for POWER7 on non-overlapped memory regions and a optimized backward memcpy for memory regions that overlap (similar to the idea of string/memmove.c). The backward memcpy algorithm used is similar the one use for memcpy for POWER7, with adjustments done for alignment. The difference is memory is always aligned to 16 bytes before using VSX/altivec instructions.

* PowerPC: strcat optimization for PPC64/POWER7Vidya Ranganathan2014-07-025-1/+99
| | | | | | This patch adds an ifunc power7 strcat symbol that uses the logic on sysdeps/powerpc/strcat.c but call power7 strlen/strcpy symbols instead of default ones.
* Fix Wundef warning for ELF_MACHINE_NO_RELASiddhesh Poyarekar2014-06-261-0/+1
| | | | | | | This patch defines ELF_MACHINE_NO_RELA on all architectures. Tested only on x86_64 to verify that the sources before and after are identical except for two instructions that pass the current line number in dl-machine.h to assert_fail.
* PowerPC: Optimized strcmp for PPC64/POWER7Vidya Ranganathan2014-06-116-1/+317
| | | | | | Optimization is achieved on 8 byte aligned strings with double word comparison using cmpb instruction. On unaligned strings loop unrolling is applied for Power7 gain.
* PowerPC: Fix optimized strncat strlen callAdhemerval Zanella2014-06-061-1/+5
| | | | | | | This patch fixes the optimized ppc64/power7 strncat strlen call for static build without ifunc enabled. The strlen symbol to call in such situation is just strlen, instead of __GI_strlen (since the __GI_ alias is just created for shared objects).
* PowerPC: Fix multiarch hypotf PPC64 pathAdhemerval Zanella2014-05-191-0/+0
| | | | This patch moves the hypotf multiarch implementation to correct path.
* PowerPC: strncpy/stpncpy optimization for PPC64/POWER7Vidya Ranganathan2014-05-0610-1/+593
| | | | | | | | The optimization is achieved by following techniques: > data alignment [gain from aligned memory access on read/write] > POWER7 gains performance with loop unrolling/unwinding [gain by reduction of branch penalty]. > zero padding done by calling optimized memset
* PowerPC: ifunc improvement for internal callsAdhemerval Zanella2014-05-056-24/+48
| | | | | | | This patch changes de default symbol redirection for internal call of memcpy, memset, memchr, and strlen to the IFUNC resolved ones. The performance improvement is noticeable in algorithms that uses these symbols extensible, like the regex functions.
* PowerPC: Fix --disable-multi-arch buildsAdhemerval Zanella2014-04-099-6/+13
| | | | | | | | | | 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.
