The implementation of memcpy/mempcpy for s390-32 (31bit) and s390-64 (64bit) is nearly the same. This patch unifies it for maintability reasons. __mem[p]cpy_z10 and __mem[p]cpy_z196 differs between 31 and 64bit: -31bit needs .machinemode "zarch_nohighgprs" and llgfr %r4,%r4 -lr vs lgr; lgr can be also used on 31bit as this ifunc variant is only called if we are on a zarch machine. __mem[p]cpy_default differs between 31 and 64bit: -Some 31bit vs 64bit instructions (e.g. ltr vs ltgr. Solved with 31/64 specific instruction macros). -The address of mvc instruction is setup in different ways (larl vs bras). Solved with #if defined __s390x__. __memcpy_mvcle differs between 31 and 64bit: -lr vs lgr; ahi vs aghi; Solved with 31/64bit specific instruction macros. Otherwise 31/64bit implementation has the same structure of the code. ChangeLog: * sysdeps/s390/s390-64/memcpy.S: Move to ... * sysdeps/s390/memcpy.S: ... here. Adjust to be usable for 31/64bit. * sysdeps/s390/s390-32/memcpy.S: Delete File. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Add memcpy. * sysdeps/s390/s390-32/multiarch/Makefile: Delete file. * sysdeps/s390/s390-64/multiarch/Makefile: Likewise. * sysdeps/s390/s390-64/multiarch/memcpy-s390x.S: Move to ... * sysdeps/s390/multiarch/memcpy-s390x.S: ... here. Adjust to be usable for 31/64bit. * sysdeps/s390/s390-32/multiarch/memcpy-s390.S: Delete File. * sysdeps/s390/s390-64/multiarch/memcpy.c: Move to ... * sysdeps/s390/multiarch/memcpy.c: ... here. * sysdeps/s390/s390-32/multiarch/memcpy.c: Delete File. |
