Subject: [PATCH 13/17] S390: Use s390-64 specific ionv-modules on s390-32, |
|
too. |
|
|
|
Upstream commit ee518b7070b1bcb41382b6db10f513e071b2c20e |
|
|
|
This patch reworks the existing s390 64bit specific iconv modules in order |
|
to use them on s390 31bit, too. |
|
|
|
Thus the parts for subdirectory iconvdata in sysdeps/s390/s390-64/Makefile |
|
were moved to sysdeps/s390/Makefile so that they apply on 31bit, too. |
|
All those modules are moved from sysdeps/s390/s390-64 directory to sysdeps/s390. |
|
|
|
The iso-8859-1 to/from cp037 module was adjusted, to use brct (branch relative |
|
on count) instruction on 31bit s390 instead of brctg, because the brctg is a |
|
zarch instruction and is not available on a 31bit kernel. |
|
|
|
The utf modules are using zarch instructions, thus the directive machinemode |
|
zarch_nohighgprs was added to the inline assemblies to omit the high-gprs flag |
|
in the shared libraries. Otherwise they can't be loaded on a 31bit kernel. |
|
The ifunc resolvers were adjusted in order to call the etf3eh or vector variants |
|
only if zarch instructions are available (64bit kernel in 31bit compat-mode). |
|
Furthermore some variable types were changed. E.g. unsigned long long would be |
|
a register pair on s390 31bit, but we want only one single register. |
|
For variables of type size_t the register contents have to be enlarged from a |
|
32bit to a 64bit value on 31bit, because the inline assemblies uses 64bit values |
|
in such cases. |
|
|
|
ChangeLog: |
|
|
|
* sysdeps/s390/s390-64/Makefile (iconvdata-subdirectory): |
|
Move to ... |
|

|
* sysdeps/s390/iso-8859-1_cp037_z900.c: ... here. |
|
(BRANCH_ON_COUNT): New define. |
|
(TR_LOOP): Use BRANCH_ON_COUNT instead of brctg. |
|
* sysdeps/s390/s390-64/utf16-utf32-z9.c: Move to ... |
|
* sysdeps/s390/utf16-utf32-z9.c: ... here and adjust to |
|
run on s390-32, too. |
|
* sysdeps/s390/s390-64/utf8-utf16-z9.c: Move to ... |
