S390: Unify 31/64bit memset.
|
|
|
077c9d |
|
|
|
077c9d |
The implementation of memset for s390-32 (31bit) and
|
|
|
077c9d |
s390-64 (64bit) is nearly the same.
|
|
|
077c9d |
This patch unifies it for maintability reasons.
|
|
|
077c9d |
|
|
|
077c9d |
__memset_z10 and __memset_z196 differs between 31 and 64bit:
|
|
|
077c9d |
-31bit needs .machinemode "zarch_nohighgprs" and llgfr %r4,%r4
|
|
|
077c9d |
-lr vs lgr and some other instructions:
|
|
|
077c9d |
But lgr and co can be also used on 31bit as this ifunc variant
|
|
|
077c9d |
is only called if we are on a zarch machine.
|
|
|
077c9d |
|
|
|
077c9d |
__memset_default differs between 31 and 64bit:
|
|
|
077c9d |
-Some 31bit vs 64bit instructions (e.g. ltr vs ltgr.
|
|
|
077c9d |
Solved with 31/64 specific instruction macros).
|
|
|
077c9d |
-The address of mvc instruction is setup in different ways
|
|
|
077c9d |
(larl vs bras). Solved with #if defined __s390x__.
|
|
|
077c9d |
|
|
|
077c9d |
Otherwise 31/64bit implementation has the same structure of the code.
|
|
