build problems on sparc64-linux

[Matthias Klose]

I see a build failure of current 6b17 from the IcedTea6 branch on sparc64-linux 
using the original hotspot, but not on sparc-linux (32bit). The build fails 
building abstractCompiler.cpp in
build/linux-sparcv9/hotspot/outputdir/linux_sparcv9_compiler2/product

.../hotspot/src/cpu/sparc/vm/assembler_sparc.hpp:1069: error: inline function 
'void Assembler::emit_long(int)' used but never defined
.../hotspot/src/cpu/sparc/vm/assembler_sparc.hpp:1083: error: inline function 
'void Assembler::add(RegisterImpl*, int, RegisterImpl*, relocInfo::relocType)' 
used but never defined
.../hotspot/src/cpu/sparc/vm/assembler_sparc.hpp:1514: error: inline function 
'void Assembler::stb(RegisterImpl*, const Address&, int)' used but never defined
.../hotspot/src/cpu/sparc/vm/assembler_sparc.hpp:1291: error: inline function 
'void Assembler::ldsb(const Address&, RegisterImpl*, int)' used but never defined
.../hotspot/src/cpu/sparc/vm/assembler_sparc.hpp:1507: error: inline function 
'void Assembler::st(RegisterImpl*, RegisterImpl*, RegisterImpl*)' used but never 
defined

these are all defined in assembler_sparc.inline.hpp. not using precompiled 
headers and -save-temps shows that assembler_sparc.inline.hpp is not included in 
the saved .ii file.

I currently fail to see how assembler_x86.inline.hpp and 
assembler_zero.inline.hpp are included (or assembler_sparc.inline.hpp on sparc 
32bit). Any hints?

patches/icedtea-sparc-trapsfix.patch is patched to include asm/traps.h
instead of asm-sparc/traps.h only for one sparc architecture. I don't see 
asm-sparc/traps.h anymore with recent kernel headers. maybe this should be build 
configure check depending on the kernel headers used?

the fedora packaging repository does have two sparc patches not found in 
IcedTea. Are these still applied? Does the fedora build acctually build and work 
in it's current state?

Thanks, Matthias
