Subject: [PATCH 10/14] S390: Use s390-64 specific ionv-modules on s390-32,
too.
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/Makefile: ... here.
* sysdeps/s390/s390-64/iso-8859-1_cp037_z900.c: 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 ...
* sysdeps/s390/utf8-utf16-z9.c: ... here and adjust to
run on s390-32, too.
* sysdeps/s390/s390-64/utf8-utf32-z9.c: Move to ...
* sysdeps/s390/utf8-utf32-z9.c: ... here and adjust to
run on s390-32, too.
