llvm dev - Oct 2010 - [LLVMdev] run into a problem with a version of GCC not listed here

dear LLVM developer team,

referring to your notes on the web-page:
http://llvm.org/docs/GettingStarted.html

i like to report, some problems with LLVM:

problem I:
------------
on my linux machine (RHEL 4.8 ) the compilation of the LLVM compiler suit works,
but
if i start to compile my C source code with clang and llc, the compiler  (llc)
abort with: Segmentation fault

0  llc 0x0883b510
Stack dump:
0.      Program arguments: /appl/c_compiler/xpic/llvm-2.7/bin/llc -O2 -f
-march=xpic new_main.bc -o new_main.s
1.      Running pass 'xpic DAG->DAG Pattern Instruction Selection' on
function '@fib_recursive'
make[1]: *** [new_main.s] Segmentation fault

question:  what does that mean?
and
how i can get more error information?

NOTE:
- i compiled the LLVM tools with
gcc (GCC) 3.4.6 20060404 (Red Hat 3.4.6-11)
and/or
gcc (GCC) 4.2.1 (Based on Apple Inc. build 5649)

on a 32bit Intel CPU with Red Hat linux RHEL 4.8
the results are the same!

problem II:
i also try to compile the LLVM tools with GCC 4.5.0 on a RHEL 4.8 machine
the compilation about with the message:

llvm[3]: Compiling xpicDelaySlotFiller.cpp for Release build
/local/build/llvm/xpic_tools_src/llvm/lib/Target/xpic/xpicDelaySlotFiller.cpp:
In member function âbool<unname
d>::Filler::isDataDependence(llvm::MachineInstr&)â:
/local/build/llvm/xpic_tools_src/llvm/lib/Target/xpic/xpicDelaySlotFiller.cpp:149:77:

r.d.tmp': No such file or directory
make[3]: ***
[/local/build/llvm/xpic_tools_src/llvm-objects/lib/Target/xpic/Release/xpicDelaySlotFiller.o]
Error

question:  what does that mean?

some good news:
i successfully build the LLVM project on a 32bit  RHEL 5.5 machine
using gcc version:
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-48)

best regards

Did you tell clang to generate code for xpic (instead of x86?).

Error
There is no xpic target in LLVM sources. You should ask that person,
whom you obtained sources from.
