problem.
I've recompiled my toolchain now with plain gnu software and the following
patches
from ftp.mvista.com and glibc-src package:
glibc22-27.patch glibc22-getaddrinfo.dpatch
glibc22-disable-static.dpatch glibc22-nss-upgrade.dpatch
glibc22-eo_EO.dpatch glibcbug.dpatch
But the problem is still there.
I couldn't find 'the cacheline patch'. Is it the one mentioned here:
http://lists.linuxppc.org/listarcs/linuxppc-embedded/200003/msg00073.html
It contains for example this lines:
--- dl-machine.c.ORIG Fri Mar 5 00:26:43 1999
+++ dl-machine.c Sat Nov 6 14:33:47 1999
@@ -250,7 +250,11 @@
PowerPC processors have line sizes of exactly 32 bytes. */
size_modified = lazy ? rel_offset_words :
PLT_INITIAL_ENTRY_WORDS;
+#ifdef PPC_CACHELINESIZE_32
for (i = 0; i < size_modified; i+= 8)
+#else
+ for (i = 0; i < size_modified; i+= 4)
+#endif
But this increment is already at +4 in my nupatched glibc.
