* String: Add hidden defs for __memcmpeq() to enable internal usageNoah Goldstein2021-10-261-0/+1
| | | | | | | | No bug. This commit adds hidden defs for all declarations of __memcmpeq. This enables usage of __memcmpeq without the PLT for usage internal to GLIBC.
* String: Add support for __memcmpeq() ABI on all targetsNoah Goldstein2021-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | No bug. This commit adds support for __memcmpeq() as a new ABI for all targets. In this commit __memcmpeq() is implemented only as an alias to the corresponding targets memcmp() implementation. __memcmpeq() is added as a new symbol starting with GLIBC_2.35 and defined in string.h with comments explaining its behavior. Basic tests that it is callable and works where added in string/tester.c As discussed in the proposal "Add new ABI '__memcmpeq()' to libc" __memcmpeq() is essentially a reserved namespace for bcmp(). The means is shares the same specifications as memcmp() except the return value for non-equal byte sequences is any non-zero value. This is less strict than memcmp()'s return value specification and can be better optimized when a boolean return is all that is needed. __memcmpeq() is meant to only be called by compilers if they can prove that the return value of a memcmp() call is only used for its boolean value. All tests in string/tester.c passed. As well build succeeds on x86_64-linux-gnu target.

* powerpc: Fix build failures with current GCCGabriel F. T. Gomes2019-05-301-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since GCC commit 271500 (svn), also known as the following commit on the git mirror: commit 61edec870f9fdfb5df3fa4e40f28cbaede28a5b1 Author: amodra <amodra@138bc75d-0d04-0410-961f-82ee72b054a4> Date: Wed May 22 04:34:26 2019 +0000 [RS6000] Don't pass -many to the assembler glibc builds are failing when an assembly implementation does not declare the correct '.machine' directive, or when no such directive is declared at all. For example, when a POWER6 instruction is used, but '.machine power6' is not declared, the assembler will fail with an error similar to the following: ../sysdeps/powerpc/powerpc64/power8/strcmp.S: Assembler messages: 24 ../sysdeps/powerpc/powerpc64/power8/strcmp.S:55: Error: unrecognized opcode: `cmpb' This patch adds '.machine powerN' directives where none existed, as well as it updates '.machine power7' directives on POWER8 files, because the minimum binutils version required to build glibc (binutils 2.25) now provides this machine version. It also adds '-many' to the assembler command used to build tst-set_ppr.c. Tested for powerpc, powerpc64, and powerpc64le, as well as with build-many-glibcs.py for powerpc targets.

* powerpc64*: fix the order of implied sysdeps directoriesGabriel F. T. Gomes2018-04-274-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The creation of the divergent sysdeps directory for powerpc64le commit 2f7f3cd8cd302bb10908c86f3f7b349df0a78e6a Author: Paul E. Murphy <murphyp@linux.vnet.ibm.com> Date: Fri Jul 15 18:04:40 2016 -0500 powerpc64le: Create divergent sysdep directory for powerpc64le. allowed float128 to be enabled for powerpc64le (little-endian) and not for powerpc64 (big-endian). Since the only intended difference between them was the presence or absence of the float128 interface, the sysdeps directory for powerpc64le explicitly reused the files from powerpc64 (through the use of Implies files). Although this works, it also means that files under the powerpc64 directory might be preferred over files under powerpc64le. For instance, on a build for powerpc64le with target set to power9, a file from powerpc64/power5 might get built, even though a file with the same name exists in powerpc64le/power8. That happens because the processor hierarchy was only defined in the sysdeps directory for powerpc64 (and borrowed by powerpc64le). This patch fixes this behavior, by creating new subdirectories under powerpc64 (i.e.: powerpc64/be and powerpc64/le) and creating new Implies files to provide the hierarchy of processors for powerpc64 and powerpc64le separately. These changes have no effect on installed, stripped binaries (which remain unchanged). Tested that installed stripped binaries are unchanged and that there are no regressions on powerpc64 and powerpc64le.

* Do not use __ptr_t.Joseph Myers2017-08-082-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

* PowerPC: multiarch bzero cleanup for PPC64Adhemerval Zanella2014-09-101-3/+2
| | | | | | | | 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).

* PowerPC: Cleaning up uneeded sqrt routinesAdhemerval Zanella2013-12-132-108/+0
| | | | | | | | For PPC64, all the wrappers at sysdeps are superfluous: they are basically the same implementation from math/w_sqrt.c with the '#ifdef _IEEE_LIBM'. And the power4 version just force the 'fsqrt' instruction utilization with an inline assembly, which is already handled by math_private.h __ieee754_sqrt implementation.

| | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00104.html One of the things I noticed when looking at power7 timing is that rlwimi is cracked and the two resulting insns have a register dependency. That makes it a little slower than the equivalent rldimi. * sysdeps/powerpc/powerpc64/memset.S: Replace rlwimi with insrdi.

I spent some time cleaning up the 64-bit power7 memcpy, in order to avoid the extra alignment traps power7 takes for little-endian. It probably would have been better to copy the linux kernel version of memcpy. * sysdeps/powerpc/powerpc32/power4/memcpy.S: Add little endian support. * sysdeps/powerpc/powerpc32/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc32/power7/mempcpy.S: Likewise. * sysdeps/powerpc/powerpc64/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power4/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/mempcpy.S: Likewise.

* PowerPC LE memcmpAlan Modra2013-10-041-326/+715
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00102.html This is a rather large patch due to formatting and renaming. The formatting changes were to make it possible to compare power7 and power4 versions of memcmp. Using different register defines came about while I was wrestling with the code, trying to find spare registers at one stage. I found it much simpler if we refer to a reg by the same name throughout a function, so it's better if short-term multiple use regs like rTMP are referred to using their register number. I made the cr field usage changes when attempting to reload rWORDn regs in the exit path to byte swap before comparing when little-endian. That proved a bad idea due to the pipelining involved in the main loop; Offsets to reload the regs were different first time around the loop.. Anyway, I left the cr field usage changes in place for consistency. Aside from these more-or-less cosmetic changes, I fixed a number of places where an early exit path restores regs unnecessarily, removed some dead code, and optimised one or two exits. * sysdeps/powerpc/powerpc64/power7/memcmp.S: Add little-endian support. Formatting. Consistently use rXXX register defines or rN defines. Use early exit labels that avoid restoring unused non-volatile regs. Make cr field use more consistent with rWORDn compares. Rename regs used as shift registers for unaligned loop, using rN defines for short lifetime/multiple use regs. * sysdeps/powerpc/powerpc64/power4/memcmp.S: Likewise. * sysdeps/powerpc/powerpc32/power7/memcmp.S: Likewise. Exit with addi 1,1,64 to pop stack frame. Simplify return value code. * sysdeps/powerpc/powerpc32/power4/memcmp.S: Likewise.
* PowerPC LE strcmp and strncmpAlan Modra2013-10-041-8/+55
| | | | | | | | | | | | | | | | | | | | | | http://sourceware.org/ml/libc-alpha/2013-08/msg00099.html More little-endian support. I leave the main strcmp loops unchanged, (well, except for renumbering rTMP to something other than r0 since it's needed in an addi insn) and modify the tail for little-endian. I noticed some of the big-endian tail code was a little untidy so have cleaned that up too. * sysdeps/powerpc/powerpc64/strcmp.S (rTMP2): Define as r0. (rTMP): Define as r11. (strcmp): Add little-endian support. Optimise tail. * sysdeps/powerpc/powerpc32/strcmp.S: Similarly. * sysdeps/powerpc/powerpc64/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/strncmp.S: Likewise. * sysdeps/powerpc/powerpc64/power4/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/power4/strncmp.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strncmp.S: Likewise. * sysdeps/powerpc/powerpc32/power7/strncmp.S: Likewise.
