* 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 LE memcmpAlan Modra2013-10-041-336/+728
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
